Seismically active areas
Based on the distribution of earthquake epicenters, the most seismically active part of the Philippines is eastern Mindanao, Samar and Leyte, with at least 16 perceptible earthquakes per year caused by the subduction of the Philippine Trench.
The other “relatively active” areas of the country are those near Dingalan Bay, Casiguran, Lubang Island and Mindoro, according to Phivolcs.
Note: Not to cause panic but a reminder for everybody to prepare
