An earthquake of magnitude 5.5 occurred only 10 minutes ago 47 km southeast of Hengchun, Taiwan, the German Research Centre for Geosciences (GFZ) reported.
The quake hit at a shallow depth of 10 km beneath the epicenter near Hengchun, Pingtung, Taiwan, in the afternoon on Tuesday 2 March 2021 at 5:22 pm 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.
A second report was later issued by Indonesia's Meteorology, Climatology, and Geophysical Agency, which listed it as a magnitude 5.5 earthquake as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 5.7.
Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.
In Hengchun (pop. 31,300) located 47 km from the epicenter, the quake should have been felt as light shaking.
Weak shaking might have been felt in Taitung City (pop. 109,600) located 98 km from the epicenter, Donggang (pop. 48,100) 100 km away, and Kaohsiung City (pop. 1,519,700) 121 km away.
