Tsunami warning maps and coastline amplitude predictions for the 2011 Tohoku-oki, Japan. Magenta star is the event hypocenter. Next to each warning map are the tsunami amplitude predictions at the coastline at 1 km intervals (black curves). The blue stars are the observed maximum amplitudes at tide gauges (TG) and the grey bars the prediction from the tsunami model at the tide gauge locations. Warning map and amplitude curves from the rapid magnitude tsunami models. For the rapid magnitude…

Maximum tsunami amplitude and timeline of events for the 2015 Mw 8.3 Illapel earthquake in Chile. (a) The maximum amplitudes are those predicted by the joint inversion of GPS, strong motion, and tide gauge data. The insets are 75 minutes of tide gauge records at the closest sites after removing tides and relative to the earthquake origin time. The amplitudes are in meters above nominal sea level. (b) Timeline of events, on the left-hand side is what would be achievable with the approach…
