Catalogue of Violent and Destructive Earthquakes in the Philippines | Page 2

peculiar conditions of life in these Islands. As far as we know, only two earthquakes which took place during the period which alone can come under consideration--that is, since the discovery of the Archipelago--have claimed a considerable number of victims, and these in the capital, because outside of Manila--if we except two or three of the principal cities--the buildings which could become dangerous during an earthquake have always been few.
Moreover, in a country in which fires consume every year thousands of dwellings and where the terrible typhoons frequently destroy whole towns with heavy loss of lives, the damage done by earthquakes has rarely been so great as to impress those occurrences indelibly upon the memory. This is beyond doubt one of the reasons why prior to the beginning of the nineteenth century hardly any data can be found concerning the numerous earthquakes which during the preceding two centuries must have occurred in the Visayas and above all on the large Island of Mindanao.
The first earthquake of which the chronicles contain a mention is that of 1599. There is no reasonable doubt that during the twenty-eight years which had then elapsed since the founding of Manila by Legaspi, several strong and possibly even destructive earthquakes occurred in this part of Luzon Island, but, as the author of the "Verdadera relaci��n de la grande destrucci��n * * * del a?o 1645" tells us, "when first founded, Manila consisted of wooden houses roofed with a certain kind of palm leaves, the same which the natives use in their buildings." Hence the damage done by these earthquakes must have been insignificant. Much more terrible were the losses caused by conflagrations which within a few years twice wiped out the entire city.
The first Bishop of Manila, Domingo de Salazar, seeing the city exposed to such general destructions by fire like the one of February 14, 1583, gave the first impulse to the construction of stone buildings and worked indefatigably in this direction. In person he explored the surroundings of Manila in quest of stone quarries and by the middle of the year 1591 he had nearly finished his palace and the cathedral, when financial difficulties caused a temporary suspension of the work. At the same time a great number of public and private buildings were under construction. The enthusiasm for structures of stone or brick with tile roofs did not diminish during the next fifty years. The chroniclers tell us that "the Spaniards began to build their houses of stone and tiles without the so necessary precautions against earthquakes. * * * Beautiful structures and dwelling houses were reared, so high and spacious that they resembled palaces; magnificent churches with lofty and graceful towers, within the walls of Manila as well as outside of them: all of which made the city very beautiful and gay and contributed equally to health and pleasure." The disaster of 1645, commonly called the earthquake of St. Andrew, as it occurred on the feast of this apostle, November 30, razed nearly every one of these buildings to the ground, and since then the style and appearance of buildings has changed greatly throughout the Archipelago, with a correspondingly great saving of lives in the subsequent earthquakes.
Masonry arches were henceforth banished from the churches; the heavy walls of the latter were further strengthened by massive buttresses; and the towers were given truly enormous substructures. But even with these precautions there is at present hardly one out of the hundreds of churches built during the seventeenth and eighteenth centuries which did not some time or other require important repairs of its masonry work or even partial reconstruction owing to earthquake damages. The only structure of this class which thus far has withstood all convulsions, is the church of St. Agustin, Manila. Nevertheless, as we have stated before, the chroniclers hardly mention all this destruction, except in a very general and cursory manner. I do not hesitate to say: they were accustomed to see similar havoc created nearly every year in one part of the Archipelago or the other by some severe typhoon, accompanied by far greater loss of lives and property, and consequently much more felt by the people than the destruction of a church, convento, municipal building ("tribunal"), one or two bridges, or other masonry structure.
In the present catalogue our aim has been to present all that is known of the various violent and destructive earthquakes on record. The first column of each page contains the ordinal number of the disturbance for purposes of reference. In the second, the date is given as accurately as it could be ascertained, Roman numerals being used to designate the months. Unfortunately, of some earthquakes only the year is known; of others, the year and month. Of one (No. 32) the approximate hour has been recorded,
