The recent improvements in the quality of seismic recordings through installation of global network of broadband stations allow for detailed studies of the source processes. The rupture histories of large deep-focus earthquakes are determined with the aim to constrain their possible mechanisms. Triangle is the Harvard CMT centroid location. Cross is the centroid location from this study. Unfilled square is the location of the rupture termination estimated by the master-event technique.
Shaded rectangle is the inferred rupture area.
Focal mechanisms are lower-hemisphere projections whose areas are proportional to the seismic moment of the subevent. Filled and unfilled areas are compressional and tensional, respectively. Triangle is the Harvard CMT centroid location. Cross denotes the centroid location from this study. The square gives the location of the rupture termination estimated by the master-event technique.
