Mild tectonic earthquakes continue to shake Surigao provinces, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.
However, the state agency said these new tremors that struck the provinces of Surigao del Sur and Surigao del Norte did not inflict any damage or injury.
The series of mild earthquakes that continuously shake Surigao provinces put the various disaster risk reduction and management councils to “standby mode” their respective personnel for any major tremor that may hit their respective areas.
In its latest bulletin, Phivolcs said a 3.8-magnitude tremor was registered today (January 23) at 1:21 a.m.
The epicenter was plotted 23 kilometers (km) southeast of Cagwait town, Surigao del Sur province.
The new tremor had a depth of 39 km, it said.
At 1:29 a.m. a magnitude 3.1 earthquake was also recorded on the same day, Phivolcs said.
The epicenter was traced only 10 km southwest from the town proper of Socorro in Siargao Island, Surigao del Norte province.
The tremor had a depth of 26 km.
Another 2.3 magnitude tremor was registered today at 7:20 a.m.
The epicenter was located 70 km northeast of Lingig town, Surigao del Sur, with a depth of 51 km, Phivolcs said.
All the new tremors that struck the Surigao provinces today were tectonic in origin and no aftershocks and tsunami alert were raised by the state agency.
The provincial disaster risk reduction and management councils there also reported no damage or injury.
It was recalled that three mild tectonic earthquakes also jolted the said province on Saturday but no reported damage or injury.
