However, the state agency said these new tremors that struck Siargao Island, Surigao del Norte province did not inflict any damage or injury.

The series of earthquakes that continuously shake Surigao del Norte province put the team commanders of various disaster risk reduction and management councils to “standby mood” their respective personnel for any major tremor that may hit their respective areas.

Surigao del Norte Gov. Sol F. Matugas alerted all personnel of the province’s DRRMCs following the series of earthquakes.

The new tremor had a shallow depth of only 1 km.

The epicenter was traced 94 km northeast of the same town and island, again with a shallow depth of 1 km.

On Monday (Sept. 10), a 5.0 magnitude tremor was recorded at 7:57 p.m. and its epicenter was traced 86 km northeast of that same town of Burgos, Siargao Island, Surigao del Norte province, with a shallow depth of 1 km, Phivolcs said.

Intensity IV was registered at the town proper of Burgos of that same island and province- Burgos, Surigao Del Norte, Intensity III in Santa Monica town of that same province, Intensity II in Surigao City and Intensity I in Palo, Leyte, the state agency said.

At 3:05 p.m. on the same day (Sept. 10), a magnitude 4.3 earthquake was also registered and its epicenter was pinpointed 43 km northeast of that same town, island and province, with a shallow depth of only 2 km, it said.
