4.3 quake 31 Jan 8:34 am (GMT +8)
A shallow magnitude 4.3 earthquake was reported in the morning near Tandag, Surigao del Sur, Caraga, Philippines.
According to the European-Mediterranean Seismological Centre (EMSC), the quake hit on Sunday 31 January 2021 at 8:34 am local time at a shallow depth of 11 km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.
A second report was later issued by the Philippine Institute of Volcanology and Seismology (PHIVOLCS), which listed it as a magnitude 4.3 earthquake as well.
Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Aras-asan (pop. 5,100) located 56 km from the epicenter, Bacolod (pop. 2,200) 58 km away, Marihatag (pop. 3,800) 59 km away, Tago (pop. 6,300) 66 km away, Tandag (pop. 29,000) 70 km away, Bislig (pop. 67,600) 96 km away, and Bah-Bah (pop. 28,600) 105 km away.
