Source time function properties indicate a strain drop independent of earthquake depth and magnitude

M Vallée - Nature communications, 2013 - nature.com
The movement of tectonic plates leads to strain build-up in the Earth, which can be released
during earthquakes when one side of a seismic fault suddenly slips with respect to the other …

Source mechanism of earthquakes in Peru
