Title: Spatial variation of slip behavior of the Philippine Fault from large surface-rupturing earthquakes to aseismic creep
Abstract:
The Philippine Fault is a strike-slip fault located at the center of the island arc, caused by the oblique subduction of the Philippine Sea Plate beneath the Luzon Arc. It extends approximately 1500 km, traversing the island arc from Luzon Island to Mindanao Island, with a left-lateral slip rate of 20–30 mm/yr. It has been the source of many major earthquakes, including the 1990 Central Luzon Earthquake (Mw7.7). On the other hand, creep displacements have been observed in the central portions of the fault, such as in Leyte Island and Masbate Island. Surveys have been conducted to quantify the extent and rate of creep. This seminar will present the results of active fault investigations, earthquake fault surveys, paleoseismic studies, and creep displacement observations, and will discuss the spatial diversity of the activity patterns of the Philippine Fault.
