Update Fri, 11 Sep 2020, 08:15
3rd large quake within 14 days
Recent quakes above magnitude 6 in Chile (past 14 days)
Recent quakes above magnitude 6 in Chile (past 14 days)
Today's earthquake is the second within a week and the 3rd of the recent series of larger earthquakes along Chile's western coast, following the magnitude 7 quake north of Huasco on 1 Sep and the similar 6.3 quake near Tongoy on 6 Sep.
This clustering suggests that currently, stress accumulated along the continental margin where the Pacific Nazca plate descends eastwards under the South American plate is currently being released along neighboring segments. As a conclusion, if this trend continues, one could expect similar earthquakes either to the south or to the north of this region in a near future.
Update Fri, 11 Sep 2020, 08:03
Reports have started to arrive, indicating that the quake could be felt as weak shaking in more than 250 km distance. Fortunately, there are no major towns in the most affected areas and there are no reports of injuries or damages so far.
This is how a surveillance camera recorded the quake at Iquique, approx. 137 km distant from the epicenter:
