A magnitude 4.8 earthquake near Guiuan, Eastern Samar, Eastern Visayas, Philippines, was reported only 20 minutes ago by Indonesia's Meteorology, Climatology, and Geophysical Agency, considered the main national agency that monitors seismic activity in this part of the world. The earthquake occurred at a shallow depth of 10 km beneath the epicenter early morning on Friday 21 May 2021 at 1:00 am local time. 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.
Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter.
Weak shaking might have been felt in Sulangan (pop. 3,000) located 70 km from the epicenter, Santa Monica (pop. 2,300) 75 km away, Guiuan (pop. 11,000) 85 km away, Libas (pop. 3,400) 91 km away, Loreto (pop. 5,400) 91 km away, Loreto (pop. 5,400) 91 km away, Loreto (pop. 5,400) 91 km away, and Del Carmen (pop. 4,300) 93 km away.
