Abstract
[...] In this thesis, data from seismic and infrasound stations were analyzed in order to see effects of tsunamis of the great Sumatra-Andaman 2004 and Tohuku-Oki 2011 earthquakes. Data used are from seismic stations of the Global Seismic Network (GSN) around the Indian and Pacific oceans and from infrasound stations of the International Monitoring System of the Comprehensive Test Ban Treaty Organization (IMS/CTBTO). In both data sets, seismic and infrasound, tsunami signals are observed in the period range of 500to2000s. These data may add to two new very useful observables for tsunami early warning systems.
