AI Thread Summary
The coast of Chile has experienced significant seismic activity, including a Mw 6.8 main shock and a Mw 6.3 aftershock within a short timeframe, followed by a Mw 6.5 aftershock later that day. The main shock occurred on September 1, 2020, approximately 85 km northwest of Vallenar, at a depth of 23 km. The aftershocks followed closely, with the Mw 6.3 occurring just 20 minutes later and the Mw 6.5 recorded later that evening. Despite the intensity of these earthquakes, there was no tsunami threat reported following the events. Additional minor earthquakes were also noted in the region during this period.
