Global rupture parameters for deep and intermediate-depth earthquakes

We investigate the global rupture parameters for deep and intermediate-depth earthquakes. From measurements of rupture duration and radiated seismic energy we estimate stress drop, apparent stress, and radiation efficiency and obtain a detailed earthquake energy budget. From scaling of the source pa...
