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.

根据地貌、历史地震和古地震资料，我们确定了菲律宾断层地震行为的沿走向变化，从大的地表破裂地震到无震蠕动。我们在1：50000比例尺的地形图上绘制了菲律宾断层的地表痕迹，并在菲律宾火山学和地震学研究所的主页上向公众提供。面对菲律宾和马尼拉海沟的海岸沿着出现的全新世珊瑚礁表明，巨型逆冲断层和相关断层在菲律宾周围产生了大型俯冲带地震，导致沿海地区隆起数米。
