The first results for the source rupture process were derived from broadband teleseismic P-waves.
The complexity is a result of the source rupture process and the induced local earthquake.
The nonlinear site effect and source rupture directivity were investigated with residual analysis.
The finite source rupture over the fault is represented in OpenSWPC using multiple sources.
First, source rupture process analysis is carried out using joint source inversion.
The numerical earthquake model includes models of source rupture and 3D wave propagation.
Several research groups have reported the source rupture process during the earthquake.
In this paper, we study the peculiar source rupture process of the earthquake, which produced the extremely large tsunami along the Sanriku coast, by making use of the OBPG records obtained above the source rupture area.
No surface rupture induced directly by source rupture can be found in the area, especially around the epicenter location.
The source rupture is expressed in OpenSWPC as the delay of the initiation time of each point source.
However, additional source rupture process information can still be retrieved from the regional full-waveform seismic data.
