Moderate-magnitude 4.9 earthquake strikes in the morning 78 km southeast of Pondaguitan, Philippines
4.9 earthquake on 12 October 7:30 a.m. (GMT +8)
According to preliminary data, the earthquake was located at a moderately shallow depth of 56 km. The exact magnitude, epicenter and depth of the quake could be revised in the coming hours or minutes, as seismologists review the data and refine their calculations, or when other agencies release their report.
A second report was then published by the Euro-Mediterranean Seismological Center (EMSC), which classified it as a 5.0 magnitude earthquake. A third agency, the German Research Center for Geosciences (GFZ), reported the same 4.9 magnitude earthquake.
Based on preliminary seismic data, the quake should not have caused significant damage, but was likely felt by many as a slight vibration in the epicenter area.
Weak tremors could have been felt in Pondaguitan (2,100 inhabitants) located 78 km from the epicenter, Surup (2,100 inhabitants) at 83 km, Nangan (3,400 inhabitants) at 90 km and Tiblawan (2,800 inhabitants) at 91 km.
Other cities close to the epicenter where the earthquake could have been felt as very weak tremors include Luzon (3,200 inhabitants) located 95 km from the epicenter and Magdug (2,300 inhabitants) 97 km away.
