BUTUAN CITY – Three mild tectonic earthquakes jolted Surigao del Sur province Thursday morning, March 26.
In its bulletin, the Philippine Institute of Volcanology and Seismology (Phivolcs) said a 2.1-magnitude earthquake was registered at 6:30 a.m.
The epicenter was plotted 73 kilometers (km) northeast in Hinatuan town, Surigao del Sur province, and had a shallow depth of only six kms, Philvocs said.
Less than an hour later, a 2.2-magnitude earthquake was recorded at 5:34 a.m. on the same day (March 26), Phivolcs said. The epicenter was traced only seven kms southwest in nearby town of Bayabas in the same province, it said.
The tremor had a depth of 58 kms, Phivolcs also said, in its bulletin. At 12:45 a.m., a 2.9-magnitude tremor was registered and its epicenter was located 93 kms northeast of Lingig town of that same province, with a depth of 35 km, it said No aftershock or tsunami alert was raised by the agency.
The three tremors were all tectonic in origin, and no damage or injury was reported by the agency.
The Surigao del Sur disaster risk reduction and management council there also reported no damage or injury.
Earthquakes are common in the Philippines which sits on the Pacific “Ring of Fire” where continental plates collide, causing frequent seismic and volcanic activities.
