The populated islands of Visayas were struck by an earthquake of magnitude w y 7.6.http://www.phivolcs.dost.gov.ph/html/update_SOEPD/2012_Earthquake_Bulletins/August/2012_0831_1247_B5F.html 2012_0831_0540 28 December 2016 The earthquake occurred at a depth of 45 km (27.9 miles). A tsunami warning was announced within the Pacific area and was lifted after two hours. The Philippine archipelago is located in the Pacific Ring of Fire, where earthquakes and volcanic activity are common. Geology The Philippine Mobile Belt is between the Eurasia plate and the Philippine Sea plate. The Philippine Sea plate is subducting along the Philippine Trench in this region. At the latitude of the earthquake, the Philippine Sea plate moves in the WNW direction at a velocity of approximately 100 mm/yr with respect to the Sunda plate. This event was an intraplate earthquake greater than 50 kilometers to the east of the boundary of the Philippine Sea plate. This earthquake was unusual in that it occurred as a result of reverse faulting within the oceanic lithosphere of the Philippine Sea plate. There have been approximately 40 events of M6 and above over the past 40 years, within 250 km of this earthquake. Most of those earthquakes were the result of normal faulting within the shallower oceanic lithosphere rather than deeper reverse faulting like this event.https://earthquake.usgs.gov/earthquakes/eventpage/usc000cc5m#summary M 7.6 – Philippine Islands region 28 December 2016 Earthquake Visayas right 250 Large earthquakes in Samar Strong earthquake events near the area were in April 1995 (7.2 Mw), May 1995 (7.1 Mw), June 1996 (7.1 Mw), and the Aug 2012 event (7.6 Mw).
