Catalogue of Violent and Destructive Earthquakes in the Philippines / With an Appendix: Earthquakes in the Marianas Islands 1599-1909

A chronological catalogue documents violent and destructive earthquakes affecting the Philippines and the Marianas between 1599 and 1909, presenting dates, locations, intensities on the De Rossi–Forel scale, and detailed accounts of local damage, casualties, and structural effects. Entries are supplemented by an introductory discussion of source limitations, the scarcity of early records, and the influence of repeated fires and typhoons on preservation of accounts. The author traces how major shocks prompted changes in building practices, summarizes significant episodes and affected localities, and includes an appendix specifically listing seismic events in the Marianas.
