“When things had quieted somewhat, I went back to the hotel to dress, and discovered that the entire wall of my room had fallen out.

“I succeeded in finding most of my clothes, and after donning them hastily went back to the work of rescue. When I got back to the street from the hotel the entire district seemed to be in flames. Fire seemed to break out of the very earth on all sides of Market street, eating up buildings as if they were so many buildings of paper. A big wholesale drug house on Seventh street exploded, throwing sparking and burning embers high into the air. These fiery pieces descended on the half-clad people in the streets, causing them to run madly for places of safety, almost crazy with the pain.

“Soon the improvised hearses began to arrive. Out of every building bodies were taken like carcasses out of a slaughter pen. Automobiles, carriages, express wagons, private equipages, and vehicles of all kinds were pressed into service and piled high with the bodies. Everywhere these wagon loads of dead bodies were being dragged through the streets, offering a spectacle to turn the most stout-hearted sick.

“With three or four sailors I went up to Seventh street to assist a number of men, women and children who had become entombed under the debris of a flat building.

“They were so tightly wedged in that we were unable to offer them any help and had to stand by and hear their cries as they were slowly roasted to death by the ever increasing flames. I can hear the cries of one of those women ringing in my ears yet – I guess I always will.

“I guess pretty nearly every bone in her body was broken. As we stood by helplessly she cried over and over again:

“‘Don’t let me die like this. Don’t let me roast. I’m cooking, cooking alive. Kill me! Shoot me – anything! For God’s sake have mercy!’

“Others joined her in the cry and begged piteously to be quickly killed before the flames reached them.

“By this time the street level had become so irregular that it was almost impossible to drag the dead wagons over them.

“Dynamite was then brought into use and the buildings were blown up like firecrackers. Flying debris was everywhere in the air, and another mad rush for safety was made, the almost naked people falling over each other in their frantic efforts to get out of the danger.

“While this excitement was at its height a man dressed only in his underclothing made his appearance among the people in a light gasoline runabout. At top speed he ran into a crowd of women, knocking them down and injuring at least a dozen. Then he turned back and charged them again. He had gone mad as a result of the scenes of death and destruction.

“Some one called for a gun, hoping that they might stop the fellow by shooting him. None was to be had, and after a desperate fight with sailors who succeeded in getting into the machine he was overpowered and turned loose.

“Everybody in the crowd, I believe, was temporarily crazy. Men and women ran helter-skelter in nothing but their night gowns, and many of them did not have on that much.”

Mrs. J. B. Conaty, of Los Angeles, was in Oakland at the time of the shock and felt the vibrations. “The suddenness with which it came upon the people,” she said, “was the most appalling thing. When I looked across the bay at ’Frisco from the Oakland shore the city seemed peacefully at sleep, like a tired baby beside its mother. With my next glance at the city I was turned almost sick.

“The ground was shaking beneath me and I thought that the end of the world was at hand. Buildings were falling to the right and left. The earth was groaning and rocking, and flames were shooting high into the sky. Soon the sound of the dynamiting reached us and buildings began to fly in the air like fireworks.

“The sea lashed itself into a fury and beat upon the shores as if it too sought to escape nature’s wrath. Over across the bay all was disorder. In the glare of the blood red flames reflected against sky and sea, white robed, half naked men and women could be seen wildly running about.

“Some of them ran to the water’s edge and threw themselves in and others less frantic had to battle with them to haul them out.

“It seemed as if every man, woman and child in ’Frisco was running toward the ferry docks. When the boat arrived on our side of the shore it was packed with men and women, none of whom seemed to be in their right senses. Many of them jumped from the boat as soon as it was made fast and ran at top speed through the streets of Oakland until forced to fall through sheer exhaustion.

“One woman in the crowd had nothing on but a night gown. In her arms she carried a 3-year-old girl who was hanging tightly to a rag doll and seemed to be the only one in the vast crowd that was unafraid. Where all these people went to I have no idea.

“I stood on the Oakland side watching ’Frisco devoured. In a space of time so short that it all seems to me like a dream now the whole city, slumbering peacefully but a moment before, presented a perdition beside which Dante’s inferno seems to pale into insignificance.”

The looters early began operations in the stricken city. The vandal thinking that law and order had gone in the general crash filled his pockets as he fled.

It was the relic hunter who opened the door to the looter. The spirit which sends the tourist tapping about the ruins of the Parthenon, awoke in San Francisco. Idle and curious men swarmed into the city, poking about in the ruins in the hope of finding something worth carrying away as a souvenir of the greatest calamity of modern times.

Scores of men and women were seen digging in the ruins of one store. They were disinterring bits of crockery, china and glassware. Strangely enough, a great deal of this sort of ware had been protected by a wall which stood through quake and fire. One woman came toiling out over a pile of brick, covered with ashes and dust, her hair dishevelled and hands grimy, but she was perfectly happy.

“See,” said she, “I found half a dozen cups and saucers as good as new. They are fine china and they will be worth more than ever now.”

I asked her if she needed them.

“Oh, dear no!” said she, laughing. “I live over in Oakland. I just wanted them to keep as souvenirs!”

Some hard-hearted jokers were abroad also. Humor dies hard, and perhaps it is just as well that it does, for the six men who started the bogus bread lines would have needed much of it if the soldiers had caught them.

The people of San Francisco had become accustomed to eating out of the hand. They put in long hours every day standing in line waiting for something to be given out. Many of them did not know what was being distributed, but they knew it would be good, so they fell into line and waited.

There were thousands of people in San Francisco who fell into a line every time they saw one. They had the bread line habit.

This impressed itself on these six men, for they went about the town and every time they found a promising spot they lined up and looked expectant. Men came and fell in behind. Women with baskets joined the brigade and in ten minutes these sidewalk comedians had a string a block long behind them and more coming every minute. Then the six jokers slipped away and left the confiding ones to wait. It was a mean trick.

The stranger and the wayfarer was made to feel at home anywhere in Oakland and the luxury of sleeping within four walls was not denied to any one. Only a few hardy men who were willing to sacrifice themselves for the good of the weaklings went without covering. The people stripped the portieres and hangings from their walls, tore up their carpets and brought in every spare piece of cloth which would do for a night’s covering. The women and children who preferred to stay indoors and on hard floors were taken care of in the public halls, the school buildings, and the basements of the churches. Beds were improvised of sheets and hay and the weaker refugees, who were beginning to go down under the strain, slept comfortably. Oakland did nobly. People shared their beds with absolute strangers, and while the newcomers in the park camps were dead to the world, those who came the day before cheered up considerably. One camp of young men got out a banjo and sang for the entertainment of the crowd.

CHAPTER XVIII.
DISASTER AS VIEWED BY SCIENTISTS

Scientists are Divided Upon the Theories Concerning the Shock That Wrought Havoc in the Golden Gate City – May Have Originated Miles Under the Ocean – Growth of the Sierra Madre Mountains May Have Been the Cause.

THE subterranean movement that caused the earthquake at San Francisco was felt in greater or less degree at many distant places on the earth’s surface. The scientists in the government bureaus at Washington believe that the subterranean land slide may have taken place in the earthquake belt in the South American region or under the bed of the Pacific Ocean. San Francisco got the result of the wave as it struck the continent, and almost simultaneously the instruments in Washington reported a decided tremor of the earth, and the oscillations of the needle continued until about noon.

At the weather bureau the needle was taken from the pivot and had to be replaced before the record could be continued. Other government stations throughout the country also noted the earthquake shock, and they agree in a general way that the disturbance began according to the record of the seismograph at nineteen minutes and twenty seconds after 8 o’clock. This would be the same number of minutes and seconds after 5 o’clock at San Francisco, which accords entirely with the time of the disaster on the Pacific Coast.

There seems to be no reason to believe the earthquake shock in San Francisco had any direct connection with the eruption of Vesuvius. That eruption had been recorded from day to day on the delicate instruments established by the weather bureau at the lofty station on Mount Weather, high up in the Virginia hills. This eruption of Vesuvius did not disturb the seismograph even at the period of great activity, but apparently Vesuvius and Mount Weather were like the lofty poles of two wireless telegraph stations, and between them there passed electrical magnetic waves encircling the earth. The records made at Mount Weather were of the most distinct character, but they showed disturbances in the air of a magnetic type and did not indicate any earthquake.

In explaining the San Francisco trembling, C. W. Hays, the director of geology in the geological survey, explained that earthquakes are, according to modern scientific theory, caused by subterranean land slides, the result of a readjustment as between the solid and the molten parts of the earth’s interior.

“The earth,” he said, “is in a condition of unstable equilibrium so far as its insides are concerned. The outer crust is solid, but after you get down sixty or seventy miles the rocks are nearly in a fluid condition owing to great pressure upon them. They flow to adjust themselves to changed conditions, but as the crust cools it condenses, hardens, and cracks, and occasionally the tremendous energy inside is manifested on the surface.

“When the semi-fluid rocks in the interior change their position there is a readjustment of the surface like the breaking up of ice in a river, and the grinding causes the earthquake shocks which are familiar in various parts of the world. The earthquake at San Francisco was probably local, although the center of the disturbance may have been thousands of miles away from that city.”

Prof. Willis L. Moore, the chief of the weather bureau, in talking of the records of the earthquake in his department, said:

“We have a perfect record of this earthquake, although we are thousands of miles away from the actual tremor itself. There were premonitory tremblings, which began at 8:19 and continued until 8:23 or thereabout. Then there was severe shock which threw the pen off the cylinder.

“According to our observations here there was a to and fro motion of the earth in the vicinity of Washington amounting to about four-tenths of an inch at the time of its greatest oscillation. These movements kept up in a constantly decreasing ratio until nearly half an hour after noon.

“San Francisco may have been a long way away from the real earthquake and merely have been within the radius of severe action so as to produce disastrous results. It is quite likely, in fact, that the greatest disturbance may have taken place beneath the bed of the Pacific Ocean.

“If it resulted in an oscillation of the earth of only a few inches there would be no likelihood of a great tidal wave. If, however, there was produced a radical depression in the bed of the ocean, the sinking of an island, or some other extraordinary disturbance, a tidal wave along the Pacific Coast would almost certainly be one of the events of this great disaster.

“There are apparently three distinct weak spots in the United States, which are peculiarly subject to earthquake shocks, and we are likely sooner or later to hear from all of them in connection with the shock at San Francisco. There is one weak area along the southern Atlantic coast in the vicinity of Charleston, another is in Missouri, and the third includes the Pacific Coast from a point north of San Francisco down to and beyond San Diego.”

In describing the instruments at the weather bureau which make the record of earthquakes, even when the movement is so small that the ordinary person does not recognize it, Prof. Moore said:

“The apparatus we have is a pen drawing a continuous line on a cylinder which revolves once every hour and is worked continuously by clockwork in an exact record of time. It moves in a straight line when there is no disturbance, and it jumps from right to left and back again when there are serious oscillations of the earth. The extent of these movements of the pen measures the grade of the oscillation. You may think it is a fantastic statement, but this seismographic pen is adjusted so delicately that it will register your step in its vicinity.

“The instrument is mounted on a solid stone foundation and what it registers is the effect of your weight pressing upon the earth. It is easy to see, therefore, that the record we have obtained of this earthquake shows a few preliminary tremblings, which seem to be premonitions, for about four minutes, then a great crash which threw the pen off the cylinder and finally a period of nearly four hours, during which there were slight tremblings of the earth, this latter period marking the readjustment after the actual shock.”

Most of the scientists were inclined to believe that the boiling process in the interior of the earth, although it goes on continuously, is subject to periods of greater or less activity. This activity may be, however, purely local, according to the scientific theory, for otherwise there would be eruptions in all the active volcanoes of the earth at the same time, and there would be earthquakes in every one of the areas where there is liability to seismic disturbances.

One government scientist in discussing the San Francisco earthquake said: “If we could have been right here in the vicinity of Washington a few hundreds of thousands of millions of years ago, we should have seen earthquakes that were earthquakes. The Alleghanies were broken up by great convulsions of the earth, and it is probable that this North American continent of ours was rocked a foot or two at a time, causing a tremendous crash of matter and the reorganization of the world itself.

“The crust, while not necessarily thinner, is not so solid. In cooling it has cracked and left fissures or caverns or jumbled strata of softer material between harder rocks, so that it is peculiarly subject to earthquakes.”

Maj. Clarence E. Dutton, U. S. A., retired, the most famous American expert on seismic disturbances, said it was probably the greatest earthquake that has occurred in this country since 1868. He declared that it undoubtedly would be followed by disturbances of less intensity in the same quarter. He stated most emphatically that the eruption of Vesuvius had no bearing whatsoever on the disturbance on the Pacific Coast.

J. Paul Goode, a professor in geology in the University of Chicago, attributes the cause of the Frisco earthquake to the Sierra Madre mountains, but not in a volcanic way, for he also claims that lava had nothing to do with the California shock. The shocks, he showed, can be attributed to mountains without volcanoes in their midst. The Sierra Madres are growing, he said, and for this reason they have shaken the city of San Francisco. He says that the gradual growing of mountains causes the underlying blocks of the earth’s crust to slip up and down and shape the top of the earth in their vicinity when they fall any great distance.

His ideas upon the subject are: “I figure that the earthquake which caused so much damage in San Francisco came from what we call the focus of disturbance. This focus at San Francisco is seven miles below the surface of the earth. As the Sierra Madre mountains grow, a phenomenon which is constantly going on, the blocks of earth below change positions; as a large block falls a series of shocks travels, up and down much the same way as the rings in the water travel out from the point at which a pebble strikes. When the vibration reaches the surface crust a severe shaking of the country adjacent is the result.

“From the actions of the earth in April of 1892, when such a severe shock was felt in San Francisco, I have no doubt but that a second earthquake will follow closely upon the one of yesterday, as the second followed the first in 1892. In that year the first came upon the 19th of April and the second upon the 21st.”

Of 948 earthquake shocks that have been recorded in California previous to 1887, 417 were most active in San Francisco. The seismographs which record the merest tremors and determine the place of the shock show that 344 have occurred since 1888. Half of the sum total have occurred in the vicinity of the gate city and for this reason it is believed that the severe shock of April 18 was the final fall of a crust of the earth which has been gradually slipping for centuries, causing from time to time the slight shocks.

The seismic physics of San Francisco and its immediate neighborhood have engaged the careful study of physical geographers. The commonly accepted opinion is one which was formulated by Prof. John Le Conte, professor of geology in the University of California, and one of the world’s geological authorities. His explanation is based upon the mountain contours of the coast of California from the Santa Barbara channel northward to the Golden Gate. In this region are represented two peninsulas, one visible, the other to be discovered through examination of the altitudes upon the map corresponding to existing geological features. This second and greater peninsula comprises the Monte Diablo and Coast ranges, separated from the Sierra elevation by the alluvial soil of the low-lying valley of the San Joaquin. This valley is contoured by the level of 100 feet and lower for a considerable portion of its length, and practically all of it lies below the level of 500 feet. The partition thereby accomplished between the Sierra mountain mass and the coastal mountains is sufficiently pronounced to indicate what was at no remote period an extensive peninsula.

This valley of the San Joaquin lies above the line of a geological fault, at a depth which can only be estimated as somewhere about a mile. The artesian well borings which have been abundantly prosecuted in the counties of Merced, Fresno, Kings and Kern afford evidence looking toward such a determination of bedrock depth. On the ocean side the continental shelf is extremely narrow. The great peninsula presents a most precipitous aspect toward the ocean basin. It is interrupted at intervals by deep submarine gorges extending close to the shore.

The oceanic basin of the Pacific is throughout a region of volcanic upheaval and seismic disturbance.

Conditioned on the one side by the known fault of the San Joaquin Valley and on the other by the volcanic activity of the Pacific basin, the greater peninsula of San Francisco in particular has always been subject, so far as the memory of white settlers can go, to frequent shocks of earthquake. In the last score or more of years seismographic observatories have been maintained at several points about San Francisco bay, and the records have been sufficiently studied to afford data for comprehension of the varied earth waves which have made themselves felt either to the perception of the citizens of the Golden Gate or to the sensitive instruments. Such observations have been conducted by Prof. George Davidson, for many years in charge of the Coast and Geodetic Survey upon the Pacific Coast; by Prof. Charles Burckhalter, of the Chabot Observatory, in Oakland, and by the staff of the Lick Observatory on Mount Hamilton.

Careful inspection of these records shows that two systems of earthquake disturbances act upon San Francisco. Those of the lighter series show a wave movement beginning in one of the easterly quadrants and more commonly in the southeastern. This series of light shocks is attributed to the slip along the line of the San Joaquin fault. While they may occur at any season of the year, they are more frequently observed when the San Joaquin river is running bank high under the influence of the melting snows in the foothills of the Sierra. That such a condition has recently existed is made clear by the report within less than a month of floods in the interior valleys of the State. Assuming, as the geologists do, that the fault in the valley lies near the roots of the Monte Diablo range, on the western edge of the alluvial plain, it will be seen that the physical factors involving the slip are very simple. There is a wide, flat plain bounded on the west by a line of weakness in the rock supports. When this plain is carrying an abnormal weight of water the tendency is to break downward at the line of the fault. This tendency will produce a jar in the mountain mass which will be rapidly communicated to its farthest extremity.

The earthquakes which have their origin in the disturbances to which the oceanic basin is subject always approach San Francisco from the direction of the southwest quadrant. These have been uniformly more violent than those whose origin is attributed to the San Joaquin fault. While the records of San Francisco earthquakes up to the present have exhibited a mild type, the damage to property having hitherto been slight, it would appear from the extent and violence of the present temblor that both causes had for once united.

The possibility of such simultaneous action of the two known seismic factors of the greater peninsula had been foreseen by Prof. Le Conte. He stated that if at any time an earthquake wave of only moderate violence should come in from the oceanic basin in sufficient strength to jar the coastal mountain masses at a period when the San Joaquin Valley was bearing its maximum weight of water the conditions would be ripe for simultaneous shocks from the southwest and from the southeast. In such a condition, while neither of the shocks by itself would be capable of doing any great amount of damage to buildings in San Francisco, the combination of two distinct sets of waves might prove too much for any work of man to withstand.

In spite of the declarations of some scientists that there can be no possible connection between the eruption of Mount Vesuvius and the earthquake of San Francisco, others are inclined to view certain facts in regard to recent seismic and volcanic activity as, to say the least, suggestive.

There is one very remarkable circumstance in regard to all this activity. All the places mentioned – Formosa, Southern Italy, Caucasia and the Canary Islands – lie within a belt bounded by lines a little north of the fortieth parallel and a little south of the thirtieth parallel. San Francisco is just south of the fortieth parallel, while Naples is just north of it. The latitude of Calabria, where the terrible earthquakes occurred last year, is the same as that of the territory affected by yesterday’s earthquake in the United States.

There is another coincidence, which may be only a coincidence, but which is also suggestive. The last previous great eruption of Vesuvius was in 1872, and the same year saw the last previous earthquake in California which caused loss of life.

Camille Flammarion expressed the opinion that the earthquake at San Francisco and the eruption at Vesuvius are directly connected. He also sees a connection between the renewed activity of Popocatepetl, Mexico’s well-known volcano, and the disturbance on the Western coast. He says that, though the surface of the earth is apparently calm, “there is no real equilibrium in the strata of the earth,” and that the extreme lateral pressure which is still forming mountains and volcanoes along the Western coast brought about an explosion of gases and the movement of superheated steam several miles below San Francisco, resulting in an earthquake.

Another theory is that the earth in revolving is flattening at the poles and swelling at the equator, and the strata beneath the surface are shifting and sliding in an effort to accommodate themselves to the new position. Other scientists scout this idea, saying that earthquakes are not caused by the adjustment of the surface of the earth, but by jar and strain as the earth makes an effort to regain its true axis.

As regards the possible connection between volcanoes and earthquakes, it is known that a violent earthquake, whose shocks lasted several days, accompanied the eruption of Vesuvius in the year 79, when Pompeii and Herculaneum were destroyed. In 1755 thousands upon thousands of people lost their lives in the memorable earthquake at Lisbon, in Portugal. At the same time the warm springs of Teplitz, Bohemia, disappeared, later spouting forth again. In the same year an Iceland volcano broke forth, followed by an uprising and subsidence of the water of Loch Lomond in Scotland. The eruption of Vesuvius in 1872 was followed soon after by a serious earthquake in California.

Coming to the present year, it is noticed that the earthquake in the island of Formosa, in which 1,000 people lost their lives, was followed by the eruption of Vesuvius on April 8. Soon after came the second great shock in Formosa, in which there was an even greater loss of life.

Later there were two earthquake shocks in Caucasia. At the same time the news of this appeared there was a report of renewed activity on the part of a volcano in the Canary Isles, which had long been dormant. In the United States two volcanoes which have been regarded as extinct for more than a century – Mount Tacoma and Mount Rainier – began to emit smoke. In regard to Tacoma, Dr. W. J. Holland, head of the Carnegie Institute at Pittsburg, says: “There is no doubt that there has been a breakdown and shifting of strata, perhaps at a very great depth, in the region of San Francisco. There certainly is great connection between this earthquake and recent private reports which have come to me of intense volcanic activity on the part of Mount Tacoma.”

On the other hand, leading scientists contend that these instances are mere coincidences. “If there is any connection between Vesuvius and the Caucasus and Canary Isles earthquakes other places would have suffered too; New York, for instance, is on the same parallel,” says Prof. J. F. Kemp, of Columbia University.

Although each of these scientists has the most absolute faith in his theory, he really knows no more about the facts than any boy on the street. No one has ever descended into the interior of the earth and investigated the heart of a volcano but Jules Verne, and he only in his mind. What is needed now is exact information. The San Francisco catastrophe will teach many lessons, and among them the necessity for the close study of both volcanoes and earthquakes. There is no reason why earthquakes and other internal disturbances cannot be observed just as closely as the weather. In fact, it is entirely probable that the time will come when a seismological bureau will exist for the study of earthquakes, just as there is a Weather Bureau for observation of the weather, and it will be the business of its officials to prophesy and warn of approaching internal disturbances of the earth, just as the weather men announce the approach of bad weather. Government observation stations will be established, exact records will be kept, and in the course of time we shall learn exactly what earthquakes are and what are their causes.

Among other lessons that the disaster has taught is that the much-maligned skyscraper is about the safest building there is. Its steel-cage structure, with steel rods binding the stone to its wall, has stood the test and has not been found wanting. Of all the mighty buildings in San Francisco those of the most modern structure alone survived. Their safety in the midst of collapsing buildings of mortar and brick argues well for like structures in other cities.

Mr. Otis Ashmore declared that the regions lying along the Pacific coast contain several of the moving strata which cause earthquakes. He said:

“While much concerning the origin of earthquakes is still a matter of doubt in the minds of scientific men, it is now generally conceded that the real cause is the sudden slipping and readjustment of the strata of rocks with the crest of the earth. As the earth is slowly cooling a very slow contraction of the earth’s crust is constantly going on, and as this crust consists very largely of stratified layers of rock, the enormous forces arising from this contraction are resisted by the solid rock.

“Notwithstanding the apparent irresistible nature of these layers of rock, they slowly yield to the enormous lateral pressure of contraction and gradually huge folds are pushed up in long mountain ranges. Usually this process goes on so slowly and gradually that the yielding of the rock masses takes place without noticeable jar, but occasionally a sudden slip occurs under the gigantic forces, and an earthquake is the result. This slip is usually only a few inches, but when two continents fall together for only a few inches enormous energy is developed.
