The Philippines lies within the zone of complex interaction between several tectonic plates, involving multiple subduction zones and one large zone of strike-slip, all of which are associated with major earthquakes. Many intraplate earthquakes of smaller magnitude also occur very regularly due to the interaction between the major tectonic plates in the region. The largest historical earthquake in the Philippines was the 1918 Celebes Sea earthquake with Mw8.3.
