I would like to bring corrections on the timeline presented at 9:11 - 40sec : JMA's EEW issuance upon M7.2 estimation (15s before S waves hit Sendai) - 3 min : JMA magnitude estimation at 7.9, major tsunami warning issued (max tsunami height forecast at 6 meters) - 28 min : Max tsunami height forecast updated to "More than 10 meters" upon buoy measurement - 35 min : Tsunami hits

16:30, discussing the vertical 5m, a video exists made of researching why. It was a slab of sediments in the scrapings by the Japan Plate on the diving Pacific, some miles wide & tens long with splay faults that let the piece rise above 2m while the plate dropped to 7m, 20km at sea a gos buoy recorded the pause between the initial rise to 2m for some seconds before rising to 7m. Done with seismic profiles alt sea, grad student lead, Tohoku Unv. irrc, can't find the video to cite, hth.

Good evening, I'm George live in Santiago, Chile, I think the strongest and continuous earthquake was Valdivia 1960, 9,7 mw 10 minutes, The 1960 Valdivia earthquake or the Great Chilean earthquake on 22 May 1960 was the most powerful earthquake ever recorded. Various studies have placed it at 9.4-9.6 on the moment magnitude scale. It occurred in the afternoon, and lasted for approximately 10 minutes.
