Applications of Fast on Seismic Event Identification and Monitoring in Mindoro Island, Philippines

Project Details

Description

Deployments and data collections of the five broadband stations in NW Mindoro over the past few years have contributed to the understanding of regional tectonics. Dip angles of subducting slabs determined by hypocentral distributions increase southeasterly from regions of ongoing to cessation of convergence with down-dip extension dominant stress patterns. The temporal development of arc-continent collision was dynamically modelled based on a simplified representation of Mindoro Island and the southern Manila Trench. Relocations of the 2017 Mw5.9 Batangas, Philippines earthquake using additional Mindoro stations result a compact series within the Batangas Bay, suggesting aseismic nature of the Balayan Bay subjecting to the geothermal impact of the Macolod Corridor. In this proposal, we employ a novel method – Fingerprints And Similarity Thresholding (FAST) - to identify seismic events in continuous data of Mindoro stations. By creating “fingerprints” of waveforms with discriminative features for search of similarity, FAST is a blind detection method without prior knowledge of waveform signatures that scores high on detection sensitivity, general applicability, and computational efficiency. We expect the resulting applications of FAST on Mindoro stations will help on a comprehensive monitoring of regional seismic activity.
