Seismic monitoring of the Indian Ocean tsunami [PDF]
Geophysical Research Letters, 2005 The 26 December 2004 Sumatra‐Andaman earthquake of Mw 9.3 triggered a massive tsunami in the Indian Ocean. We here report on observations of the Indian Ocean tsunami at broadband seismic stations located on islands in the area. The tsunami induces long‐period (>1000 s) signals on the horizontal components of the sensor. Frequency‐time analysis shows
