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

"Catalogue of Violent and Destructive Earthquakes in the Philippines" by Rev. Miguel Saderra Masó is a scientific publication written in the early 20th century. The work serves as a comprehensive list and analysis of significant earthquakes that affected the Philippines from 1599 to 1909, detailing their intensity, damage, and geographical areas impacted. This catalog not only provides historical insights into the seismic activity in the region but also aims to contribute to the broader scientific understanding of earthquakes globally. The opening of the text outlines the rationale for its creation, explaining how it responds to a request from the seismologist Prof. John Milne for a consolidated list of destructive earthquakes to include in an international catalog. Saderra Masó discusses the challenges of compiling an accurate historical record due to the general lack of detailed accounts from earlier chroniclers regarding earthquake events. He emphasizes the differences in documentation between significant seismic occurrences before and after 1800 and proposes a systematic classification of earthquakes based on their impact to provide a clearer understanding of their effects on the region. The text sets the stage for a thorough examination of the earthquakes that have shaped the Philippine landscape throughout history.
