Fig. 4From: 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 observations and nonlinear dispersive wave (NDW) simulation results for the San Francisco and San Diego tide gauge stations. Black and blue curves show the observed and simulated waveforms, respectively, after application of low- and high-bandpass filters with cut-off periods of 16 and 128 min, respectivelyBack to article page
