Puterman, I think your hunch concerning the 10 km depths being reworked as the seismologists get caught up is right on the money.
Remember back on the 11 and 12 April 2012, after the (2) Sumatra mag 8's, how there seemed to be an outbreak of triggered seismicity around the globe?
Magnitude 6.9 GULF OF CALIFORNIA April 12, 2012
Magnitude 6.5 MICHOACAN, MEXICO April 11, 2012
Magnitude 5.9 OFF THE COAST OF OREGON April 11, 2012
We haven't seen anything similar following the Solomon Islands unleashing. In fact, the only Mag 5.0+ eq since the Mag 8.0 that isn't related to
Indo-Australian plate movement is this 5.0
on the northern Mid-Atlantic
It's as if the rest of the world has taken a nap. Just an observation...
One last thing. Did anyone notice the fault mechanism ascribed to the
Mag 7.0 01:54:15 UTC
aftershock? (It's the big yellow dot just
north of Lata)
Strike-slip rupture at only 9.8 km depth. Whereas, the mainshock was a really shallow-dipping thrust fault with a hypocenter nearly 3 times as
I can't fathom the contorted stresses necessary to cause all these different mechanisms and depths; those rocks are tortured.
ETA: Thanks for linking that PDF, Puterman.
