The 2011 Tohoku-Oki earthquake (Mw9.0) ruptured a large portion of the plate boundary where the coupling was considered weak and represented by sparsely distributed small asperities. A typical asperity break produced an event of around Mw7.5 accompanied by a subsequent expansion of aftershock activity beyond the main rupture zone. Unlike previous large earthquakes, the Mw9.0 earthquake sequence does not show much spatial expansion of aftershock activity, but the areas of slip deficit in the...[Show more]
