Here is the first event of 09 October 2022. #FocalMechanism determined with #SCARDEC method from #Geoscope #NationalService. This is a very deep earthquake, among the deepest that are detected (~650 km). These events occur at the depth where the subduction plane hits the boundary between upper and lower mantle. The event was actually a sequence of three ~M.6.5 events, which is already remarkable. Source: http://geoscope.ipgp.fr/index.php/en/catalog/earthquake-description?seis=us7000ingh
