Update Sun, 18 Apr 2021, 13:39Moderate 4.9 quake hits near Hakha, Chin State, Myanmar (Burma)
4.9 quake 18 Apr 7:54 pm (GMT +6:30)
A shallow magnitude 4.9 earthquake was reported early evening near Hakha, Chin State, Myanmar (Burma).
According to the German Research Centre for Geosciences (GFZ), the quake hit on Sunday 18 April 2021 at 7:24 pm local time at a shallow depth of 10 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 France's Réseau National de Surveillance Sismique (RéNaSS), which listed it as a magnitude 5.2 earthquake. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 4.9.
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 Hakha (pop. 20,000) located 55 km from the epicenter, and Falam (pop. 5,400) 71 km away.
Other towns or cities near the epicenter where the quake might have been felt as very weak shaking include Monywa (pop. 182,000) located 114 km from the epicenter.
