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

This catalog offers a rare window into three centuries of seismic catastrophe in the Philippines. Saderra Masó, a Jesuit priest and volcanologist, systematically documents every destructive earthquake from 1599 to 1909, transforming dry data into an unsettling chronicle of a nation built on fire. He ranks quakes by intensity and damage, reconstructing the violent earth that shaped Philippine history in ways its colonial administrators could not ignore. The work originated as a contribution to international seismology, responding to Professor John Milne's call for a global earthquake catalog. But what emerges is far more than scientific record-keeping. Saderra Masó honestly confronts the limits of his sources: before 1800, chroniclers offered only fragmentary accounts, their descriptions vague and inconsistent. After 1800, documentation improves dramatically, and the catalog gains terrible specificity. We see cities leveled, churches collapsed, coastlines reshaped. For anyone curious about Philippine history, disaster studies, or the colonial-era scientific mind at work, this catalog is a singular artifact. It maps destruction across centuries, revealing how often the ground itself proved as dangerous as any colonizer.
