Anomalously steep dips of earthquakes in the 2011 Tohoku-Oki source region and possible explanations

The 2011Mw 9.1 Tohoku-Oki earthquake had unusually large slip (over 50m) concentrated in a relatively small region, with local stress drop inferred to be 5–10 times larger than that found for typical megathrust earthquakes. Here we conduct a detailed analysis of foreshocks and aftershocks (Mw 5.5–7....
