Fig. 2.From: Along-dip segmentation of the 2011 off the Pacific coast of Tohoku Earthquake and comparison with other megathrust earthquakesMulti-orbit long-period surface waves for the 2011 off the Pacific coast of Tohoku Earthquake. Waveforms are vertical component with a bandpass filter from 3 to 10 mHz. Amplitudes decay systematically in time at stations in any directions from the source, representing a point-like source.Back to article page
