Whereas system 2 showed increasing larger magnitudes with time along with smaller magnitudes varying with the pumping stages...

... ABSTRACT: The moment magnitude is the preferred magnitude to characterize the earthquake source. Moment magnitudes ( M w ) are calculated from moment tensor inversion. In contrast, the regional short period surface-wave magnitude ( M blg ) and local magnitude ( M L ) are calculated using...
