Peru Mw 8.0 August 15, 2007
Backprojection movies and snapshots.
TA = US Array ~200 stations, filtered from 0.8-2.0Hz, linear stacking
GSN = 13 GSN stations ~equally (in azimuth) distributed, filtered 0.05 - 2.0Hz, cube root stacking
TA doesnt show much directivity because the stations only go from 60-70 deg in distance and only
span about 11 deg in azimuth. P's moveout at these distances and this limited ray
parameter (distance) coverage hinders TA from seeing the southern propagation.
GSN however, only uses 13 stations and indeed sees a jump to the south.
Put your mouse over the center of the first red blob at 100 seconds
and then watch the second part of the rupture appear more to the south.
