Magnitude 4.9 quake hits GenSan

GENERAL SANTOS CITY, Jan. 13 – A magnitude 4.9 earthquake was recorded in this city early Thursday but the Philippine Institute of Volcanology and Seismology (Phivolcs) said the temblor was hardly felt in the area.

Bedoria Abdullah, science research specialist of the Phivolcs station here, told PNA the quake registered with their seismic machine at around 12:42 a.m. but they did not issue any report on its intensity.

“It’s considered a micro earthquake that has been actually occurring on a daily basis. It was picked up by our machine but we declared it as a no intensity quake since it was not much felt in our area,” she explained.

A Phivolcs report noted that the quake was tectonic in origin and its epicenter was traced at 152 kilometers south of this city.

Its depth of focus was measured at 505 kilometers deep and occurred mainly at a portion of the seas off this city.

Abdullah said allayed concerns regarding the occurrence of the latest earthquake, which is so far the second temblor recorded this month above magnitude 4.5.

She said the earthquakes that so far occurred in the area were all tectonic in origin or caused by normal plate movements and they have yet to record any volcanic-related temblor in the area.

This city and nearby South Cotabato and Sarangani provinces lists at least two active volcanoes – Mt. Matutum in Polomolok town and Mt. Melebingoy (formerly Mt. Parker) in T’boli town, both in South Cotabato.(PNA)
