Philippines – M 5.1 – Moderate earthquake in the coastal waters of Mindanao

Earthquake Report comment :
The earthquake occurred at a depth of 66 km, thus widening but at the same time softening the impact.
Weak shaking has been perceived by inhabitants from Davao.

Mindanao is a seismically very active area in the Philippines. On July 23, 2010 a very powerful M 7.6 earthquake struck the in Moro Gulf  (western side of Mindanao) .  The earthquake did not generate a Tsunami and was not damaging because the hypocenter (depth) was at 612 km. This earthquake (and a number of heavy aftershocks) could be felt as far as Indonesia, Brunei, Malaysia and Singapore.

Off the coast of eastern Mindanao is the Philippine Trough, which descends to a depth of 10,430 meters. The Philippines is part of a western Pacific arc system that is characterized by active volcanoes. Among the most notable peaks are Mount Mayon near Legazpi City, Taal Volcano south of Manila, and Mount Apo on Mindanao. All of the Philippine islands are prone to earthquakes. (Source : Wikipedia)
