Research Abstract |
We identified an along-strike variation of seismic behavior of the Philippine fault from large surface-rupturing earthquakes to aseismic creeping based on geomorphic, historical earthquake, and paleoseismic data. We mapped the surface trace of the Philippine fault on 1 : 50, 000-scale topographic maps and made them available to the public on the homepage of the Philippine Institute of Volcanology and Seismology. Holocene raised coral reefs along the coast facing to the Philippine and Manila trenches suggest that the mega-thrust and related faults have generated large subduction zone earthquakes around the Philippines that caused uplift of the coastal areas on the order of several meters.
