BUTUAN CITY – A 4.1 magnitude earthquake jolted Siargao Island on Tuesday, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.
In its bulletin, Phivolcs said the earthquake struck at 11:40 p.m. on Tuesday, April 30, and its epicenter was plotted 43 kilometers (km) southeast of Pacific Ocean facing town of General Luna, Siargao Island, Surigao del Norte province.
The new earthquake had a depth of 10 km.
At 11:53 p.m. on April 30, a 4.0 magnitude tremor was again registered and its epicenter was traced 54 km southeast of General Luna, with a depth of 13 km, Phivolcs said.
The two tremors were tectonic in origin and no aftershock alert was raised by the agency.
The province and municipal disaster risk reduction and management councils (DRRMCs) there reported no damage and injury.
Six mild tectonic earthquakes were also recorded on Wednesday morning, May 1, 2019, Phivolcs said.
Rescue teams and personnel of the DRRMCs are still on standby due to the series of tremors the past two weeks.
The Philippines lies in the Pacific “Ring of Fire” where colliding plates in the Earth’s crust cause frequent earthquakes and volcanic activity.
