A MAGNITUDE 6.0 earthquake struck the Batuan town in Masbate Thursday, the Philippine Institute of Volcanology and Seismology (Phivolcs).

The earthquake jolted the province at about 2:10 a.m., which had a depth of 10 kilometers, it said.

Prior to this, Masbate also experienced a magnitude 4.5 earthquake in the town of Dimasalang on Wednesday.

This means the magnitude 6 earthquake felt in Batuan town was the mainshock of magnitude 4.5 foreshock yesterday.

According to the United States Geological Survey, foreshocks are earthquakes that are relatively smaller in magnitude and come before the larger earthquake in the exact location in a sequence.

As of 7 a.m., there were a total of 70 recorded aftershocks, of which seven were felt in the area with a magnitude range between 1.6 to 4.2, Phivolcs said in an 8:40 a.m. bulletin report.

Due to the earthquake, Phivolcs reported the highest intensity VII in the city of Masbate, while intensity V was recorded in the towns of Dimasalang, San Fernando, and Uson, Masbate.
