PHIVOLCS
Aftershocks continued to occur following the magnitude 6.9 earthquake on Sept. 30, with the Philippine Institute of Volcanology and Seismology (Phivolcs) logging more than 2,000 aftershocks as of 6 a.m., Thursday, Oct. 2.
Phivolcs reported 2,461 aftershocks, of which 498 were plotted by three or more seismic stations.
The tremors had magnitudes ranging from 1.0 to 5.0, though only 13 were felt.
Despite the high number of recorded aftershocks, most were too weak to be noticed without instruments.
Phivolcs earlier warned that aftershocks may persist for days to weeks after the main shock.
