The shock was most severe in the northern part of the town, nearest to the mountain of La Silla, which rises like a vast dome, with steep cliffs in the direction of the sea. The churches of the Trinity and Alta Gracia, the latter of which was more than one hundred and fifty feet high, and the nave of which was supported by pillars twelve or fifteen feet thick, were reduced to a mass of ruins not more than five or six feet high. The subsidence of the ruins was such that scarcely a vestige of pillar or column could be found. The barracks of San Carlos disappeared altogether, and a regiment of infantry, under arms to take part in a procession, was swallowed up with the exception of a few men.

Nine-tenths of the town was annihilated. The houses which had not collapsed were cracked to such an extent that their occupants did not dare to re-enter them. To the estimate of 10,000 victims caused by the earthquake, must be added the many who succumbed, weeks and months afterward, for want of food and relief. The night of Holy Thursday to Good Friday presented the most lamentable spectacle of desolation and woe which can well be conceived. The thick layer of dust, which, ascending from the ruins, obscured the air like mist, had again settled on the ground; the earthquake shocks had ceased, and the night was calm and clear. A nearly full moon lighted up the scene, and the aspect of the sky was in striking contrast with that of a land strewn with corpses and ruins.

Mothers might be seen running about with their children whom they were vainly trying to recall to life. Distracted families were searching for a brother, a husband, or some other relative, whose fate was unknown to them, but who, they hoped, might be discovered in the crowd. The injured lying half buried beneath the ruins were making piteous appeals for help, and over 2,000 were extricated. Never did human kindness reveal itself in a more touching and ingenious fashion than in the efforts made to relieve the sufferers whose cries were so heart-breaking to hear. There were no tools to clear away the rubbish, and the work of relief had to be performed with the bare hands.

The injured and the sick who had escaped from the hospitals were carried to the banks of the river Guayra, where their only shelter was the foliage of the trees. The beds, the lint for binding up wounds, the surgical instruments, the medicines and all the objects of immediate necessity were buried beneath the ruins, and for the first few days there was a scarcity of everything, even of food. Water was also very scarce inside the town, as the shock had broken up the conduits of the fountains and the upheaval had blocked the springs that fed them. In order to get water it was necessary to descend to the river Guayra, which had risen to a great height, and there were very few vessels left to get it in.

It was necessary, also, to dispose of the dead with all dispatch, and in the impossibility of giving decent burial to so many thousand corpses, detachments of men were told off to burn them. Funeral pyres were erected between the heaps of ruins, and the ceremony lasted several days.

The fierce shocks which had in less than a minute occasioned such great disasters could not be expected to have confined their destructive effects to one narrow zone of the continent, and these extended to a great part of Venezuela, all along the coast and specially among the mountains inland. The towns of La Guayra, Mayquetia, Antimano, Baruta, La Vega, San Felipe, and Merida were entirely destroyed, the number of deaths exceeding 5,000 at La Guayra and San Felipe.

In November, 1822, the coast of Chile began to be violently convulsed by a succession of shocks, the first of which was of great severity. The heavings of the earth were quite perceptible to the eye. The sea rose and fell to a great extent in the harbor of Valparaiso, and the ships appeared as if they were first rapidly forced through the water, and then struck on the ground. The town of Valparaiso and several others were completely overthrown. Sounds like those produced by the escape of steam accompanied this earthquake, and it was felt throughout a distance of 1,200 miles along the coast, a portion of which—extending to about 100 miles—was permanently raised to a height varying from two to four feet. At Quintero the elevation was four feet, and at Valparaiso three feet; but about a mile inland from the latter place the elevation was as much as six or seven feet; while the whole surface raised is estimated at nearly 100,000 square miles.

The year 1868 proved very disastrous in South America. On the 13th of August of that year a series of shocks commenced which were felt over a large extent of country, stretching from Ibarra on the northwestern border of Ecuador to Cabija on the coast of Bolivia, a distance of about 1,400 miles. The effects were most severe about the southern portion of the Peruvian coast, where the towns of Iquique, Arica, Tacna, Port Ilay, Arequipa, Pisco, and several others were destroyed, and in the northern parts of Ecuador, where the town of Ibarra was overthrown, burying nearly the whole of the inhabitants under its ruins. A small town in the same quarter, named Cotocachi, was engulfed, and its site is now occupied by a lake. The total loss of lives is estimated at upward of 20,000.

On May 15, 1875, earthquake shocks of a serious character were experienced over large areas of Chile. At Valparaiso the shock lasted for forty-two seconds, with a vertical motion, so that the ground danced under foot. Two churches and many buildings were damaged. Another earthquake occurred at Valparaiso, July 8, when there were six shocks in succession. The inhabitants took refuge in the streets, several people were killed, and much damage was done to property.

About the middle of May, 1875, a most disastrous earthquake visited New Granada, the region of its influence extending over an area 500 miles in width. It was first felt perceptibly at Bogota; thence it traveled north, gaining intensity as it went, until it reached the southeast boundary line of Magdalena, where its work of destruction began. It traveled along the line of the Andes, destroying, in whole or in part, the cities of Cucuta, San Antonio, and Santiago, and causing the death of about 16,000 persons. On the evening of May 17, a strange rumbling sound was heard beneath the ground, but no shock was felt. This premonitory symptom was followed on the morning of the 18th by a terrific shock. “It suddenly shook down the walls of houses, tumbled down churches, and the principal buildings, burying the citizens in the ruins.” Another shock completed the work of destruction, and shocks at intervals occurred for two days. “To add to the horrors of the calamity, the Lobotera volcano, in front of Santiago, suddenly began to shoot out lava in immense quantities in the form of incandescent balls of fire, which poured into the city and set fire to many buildings.”
