Analysis of Rupture Directivity for the 2004 Sumatra Earthquake from the Rayleigh-Wave Phase Velocity

Analysis of Rupture Directivity for the 2004 Sumatra Earthquake from the Rayleigh-Wave Phase Velocity

The rupture directivity for the 2004 Sumatra earthquake is analyzed by examining differences between the phase-de lay times of Rayleigh-waves (in the 140 - 160 sec period range) arising from the main shock and reference earth quakes. A long source-process time (~463.0 sec) and large rupture length (...
