"Minor to moderate-magnitude earthquakes may be expected to occur in the vicinity of the epicentral area and may persist for several days to weeks, with the possibility of some being felt at various intensities," Phivolcs said.

As previously advised, people are reminded to be cautious of structures that are visibly weakened by ground shaking during the 16 October 2019 M6.3, the 29 October 2019 M6.6 and the 31 October 2019 M6.5 earthquakes.

Preparedness of communities is highly encouraged and people are enjoined to protect themselves by doing the “drop, cover and hold” procedure during a strongly felt earthquake.

DOST-PHIVOLCS Quick Response Team (QRT) is currently investigating the geologic impacts, assessing structural damages, establishing additional portable seismic stations in the vicinity of the earthquake epicenters to augment existing seismic monitoring network, to monitor and study ongoing occurrence of earthquake events.
