Fig. 7From: Time difference between the 1854 CE Ansei–Tokai and Ansei–Nankai earthquakes estimated from distant tsunami waveforms on the west coast of North AmericaComparison of observed and simulated waveforms of the 1854 CE Ansei–Nankai tsunami recorded at the a San Francisco and b San Diego tide gauge stations. Black, blue, red, and green curves show the observations, simulations, and simulations shifted by − 0.4 h and + 1.3 h, respectivelyBack to article page
