Tohoku, Japan Earthquake: Aftershock (and Foreshock) Sequence, M:Time History
Tohoku, Japan Earthquake: Finite Fault Model USGS V1 - 7 hrs after OT Compact rupture, mostly bilateral about epicenter, peak slip up dip of hypocenter. Rupture was likely restricted to the shallow trench, and GPS vectors suggest slip did not reach the plate boundary beneath the coastline. Peak slips closer to 40+ m, inferred from updated modeling. Box is 580 km long and 190 km wide Zone of main slip is 300 km long and ~150 wide
