Figure

Figure S1. (a) 2-8 Hz band-pass-filtered envelope functions showing the moveout of tremor east of GTBY during the teleseismic surface waves of 2011 M_w9.0 Tohoku-Oki earthquake. The red lines mark the hand-picked peaks of 6 tremor bursts. (b) Broadband velocity seismograms recorded at station GTBY. The top, middle and bottom traces are transverse, radial and vertical components, respectively. (c) 2-8 Hz band-pass-filtered envelope functions showing the moveout of tremor southwest of GTBY during the teleseismic surface waves.

Movies

Movie S1 [H.264-encoded MPEG4 Movie; 1.4 MB]. Tremor in Cuba recorded at station CU.GTBY triggered by the 2010 M_w8.8 Chile earthquake. (Top) Broadband transverse-component seismogram recorded at the station GTBY. (Middle) 5 Hz high-pass-filtered transverse-component seismogram showing the earthquake and tremor signals during the teleseismic waves. (Bottom) Spectrogram of the transverse-component seismogram from station GTBY. The triggered tremor signals can be identified by the narrow vertical bands indicating richness in high-frequency energy. The sound is generated by speeding up the seismic data by 100 times.

Movie S2 [H.264-encoded MPEG4 Movie; 2.2 MB]. Tremor in Cuba recorded at station CU.GTBY triggered by the 2011 M_w9.0 Tohoku-Oki earthquake. Other symbols and notations are the same as in Movie S1.
