3. Philippines in the Pacific Ring of Fire

4. Tectonic Summary
The broad-scale tectonics of the Philippine Islands are dominated by the west-northwest convergence of the Philippine Sea plate with respect to the Sunda plate. This motion, about 10 cm/year at the latitude of the earthquake of February 6, 2012, is accommodated by subduction along the east and west sides of the Philippines Archipelago and by motion of micro plates and distributed deformation within the Archipelago. The February 6 earthquake occurred as thrust-faulting within the archipelago. Several earthquakes similar in size to the February 6 earthquake occurred within the archipelago in eastern Negros, Cebu, and Bohol in the twentieth century. In 1948 a magnitude 8.1 earthquake occurred about 150 km to the west of the February 6 earthquake in a zone of shallow seismicity that is associated with subduction along the Negros Trench on west side of the Philippines Archipelago.

9. Philippines earthquake toll rises as dig continues for landslide casualties
Rescuers have found no further survivors among dozens of people buried by landslides on a central Philippine island after an earthquake. The death toll has climbed to 15, with more than 70 people missing.

10. Tsunami Information
The earthquake locations and magnitudes cited in NOAA tsunami statements and bulletins are preliminary and are superseded by USGS locations and magnitudes computed using more extensive data sets.
