A shallow magnitude 4.3 earthquake was reported in the morning near Sinabang, Kabupaten Simeulue, Aceh, Indonesia.
According to Indonesia's Meteorology, Climatology, and Geophysical Agency, the quake hit on Saturday 3 April 2021 at 7:51 am 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 the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 4.3 earthquake as well.
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 Sinabang (pop. 15,000) located 48 km from the epicenter.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
