6.0 quake hits Davao Or town

A DAY following the twin earthquakes felt in Baganga, Davao Oriental, another town in the province experienced seismic activity, this time in Governor Generoso.

On the afternoon of Friday, March 8, at 5:11 p.m., a magnitude 6.0 earthquake struck Governor Generoso, as reported by the Philippine Institute of Volcanology and Seismology (Phivolcs). Earlier, it was reported as 6.1.

The epicenter of the earthquake was located 135 kilometers (km) within the town, with a depth of 143 kilometers. This tremor was tectonic, caused by the movement of an active fault near the area.

Phivolcs’ instruments recorded the quake at Malungon, Sarangani; Sarangani and Don Marcelino in Davao Occidental; and Davao City.

Intensity III was recorded in Digos City, Sta. Cruz and Matanao in Davao del Sur; Tagum City in Davao del Norte; Nabunturan and Pantukan in Davao de Oro; Glan in Sarangani; Tupi and Koronadal City in South Cotabato; and Lutayan in Sultan Kudarat.

Intensity II was reported in Magsaysay, Davao del Sur; General City; and Malapatan, Alabel, and Kiamba in Sarangani; Tampakan, Banga, Polomolok, Tantangan, Surallah, and Santo Niño in South Cotabato.

Intensity I was recorded at President Quirino, Columbio, Isulan, Lambayong, and Senator Ninoy Aquino in Sultan Kudarat; and Lake Sebu and Norala, South Cotabato.

Reported intensity is the traditional method of assessing the quake’s impact based on reports from people who felt it.

On the other hand, instrumental intensity is measured using a meter that gauges ground acceleration. (Read full story on sunstar.com.ph/davao)
