A tectonic earthquake shook Bislig City anew this Monday morning, the Philippine Institute of Volcanology and Seismology (Phivolcs) said.
In its bulletin, Phivolcs said a 3.1 magnitude tremor was recorded at 2:06 a.m. Monday and its epicenter was plotted 39 kilometers northeast of Bislig City, Surigao del Sur.
The earthquake has a depth of only 11 km, the state agency said.
No aftershock or tsunami alerts was raised by the state agency.
Bislig City and Surigao del Sur disaster risk reduction and management councils also reported no damage or injury there.
On June 16, a 4.9 magnitude earthquake also rattled residents in this same southern-tip city of Bislig. The epicenter was traced 55 km, with a shallow depth of only 6 km, Phivolcs added.
Disaster councils there also reported no damage or injury in that last week tremor that registered at 9:44 a.m. of that day.
