Significant magnitude 5.4 quake hits 130 km northwest of Sinabang, Indonesia early morning
5.4 quake 15 Sep 3:13 am (GMT +7)
5.4 quake 15 Sep 3:13 am (GMT +7)
An earthquake of magnitude 5.4 occurred early morning on Wednesday, September 15th, 2021, at 3:13 am local time near Sinabang, Kabupaten Simeulue, Aceh, Indonesia, as reported by Indonesia's Meteorology, Climatology, and Geophysical Agency.
According to preliminary data, the quake was located 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 German Research Centre for Geosciences (GFZ), which listed it as a magnitude 5.4 earthquake as well. A third agency, the European-Mediterranean Seismological Centre (EMSC), reported the same quake at magnitude 5.4.
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 130 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.
