MANILA, Philippines – The Philippine Institute of Volcanology and Seismology (Phivolcs) on Tuesday recorded two moderate earthquakes in Luzon and Mindanao.
The Luzon quake, measuring a magnitude of 5.3, occurred at 2:13 a.m.
The epicenter was traced 69 kilometers northwest of Itbayat town in Batanes province.
Phivolcs said the tremor, which was unfelt, had a shallow depth of five kilometers.
Meanwhile, the quake in Mindanao, which measured magnitude 4.6, was recorded at 9:51 a.m.
Phivolcs estimated its epicenter some 44 kilometers northeast of Burgos town in Surigao Del Norte province.
The tremor had a shallow depth of four kilometers.
Phivolcs said the quake was felt at Intensity 2 in the towns of Burgos and Sta. Monica in Surigao Del Norte, as well as in San Francisco, Southern Leyte.
The agency also monitored Instrumental Intensity 1 at Surigao City, Surigao Del Norte.
John Deximo, science research analyst of the Phivolcs Earthquake Monitoring Division, said there were no reported casualties or damages from both tectonic quakes and no aftershocks were expected.
Deximo said the possible source of the tremor in Batanes was the movement along an offshore fault in the province, while movement from the Philippine Trench that runs roughly from waters off Aurora down to Samar and past Mindanao possibly triggered the quake in Surigao del Norte. – RBA
