From: Unusual low-angle normal fault earthquakes after the 2011 Tohoku-oki megathrust earthquake
Comparison of waveforms between the 2014 Fukushima-oki earthquake and the 2011 low-angle normal fault aftershock. a The red triangles and yellow star indicate the global seismic stations used in this study and the epicenter of the 2014 Fukushima-oki earthquake, respectively. b Black and red lines indicate observed seismograms for the 2014 Fukushima-oki earthquake and the largest low-angle normal fault aftershock on 12 March 2011, respectively. Waveforms were band-pass filtered between 0.005 and 0.04 Hz, with a sampling rate of 2 Hz. The station code, maximum amplitudes, azimuth, and distance from the epicenter are indicated for each waveform. The figure was generated with Generic Mapping Tools (Wessel and Smith 1998)
