Magnitude 5.5 earthquake strikes near Banda Aceh, Kota Banda Aceh, Aceh, Indonesia
5.5 quake 17 Apr 8:04 am (GMT +7)
5.5 quake 17 Apr 8:04 am (GMT +7)
An earthquake of magnitude 5.5 occurred only 16 minutes ago 61 km south of Banda Aceh, Indonesia, Indonesia's Meteorology, Climatology, and Geophysical Agency reported.
The quake hit at an intermediate depth of 88 km beneath the epicenter near Banda Aceh, Kota Banda Aceh, Aceh, Indonesia, in the morning on Saturday 17 April 2021 at 8:04 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.
A second report was later issued by the European-Mediterranean Seismological Centre (EMSC), which listed it as a magnitude 5.1 earthquake. A third agency, the German Research Centre for Geosciences (GFZ), reported the same quake at magnitude 4.7.
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 Banda Aceh (pop. 250,800) located 61 km from the epicenter, Sigli (pop. 17,500) 85 km away, Sabang (pop. 24,500) 100 km away, Reuleuet (pop. 40,400) 112 km away, and Meulaboh (pop. 35,100) 131 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
