5.3 quake 15 Apr 7:33 pm (GMT +11)

A shallow magnitude 5.3 earthquake was reported early evening near Attu Station, Aleutians West, Alaska, USA.
According to the United States Geological Survey, the quake hit on Thursday 15 April 2021 at 7:33 pm local time at a shallow depth of 10.4 miles. 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.
Our monitoring service identified a second report from France’s Réseau National de Surveillance Sismique (RéNaSS) which listed the quake at magnitude 5.1. Other agencies reporting the same quake include the European-Mediterranean Seismological Centre (EMSC) at magnitude 5.3, and the German Research Centre for Geosciences (GFZ) at magnitude 5.0.
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 Attu Station (pop. 21) located 81 miles from the epicenter.
