[MIS34-P12] Seismic quiescence prior to the 2016 Kumamoto Earthquakes
Keywords:seismic quiescence, Kumamoto
We applied the above RTM algorithm to 2016 Kumamoto Earthquake swarm and detected clear seismic quiescence in the western Kyushu Island. The seismic quiescence started at around beginning of 2015 and ended March 2016. The main shock of M7.3 occurred just the edge of seismic quiescence region. It is well consistent with the past examples (e.g. 1995 Kobe EQ). In the presentation, we would like to present the results of parameter search and robustness of the obtained quiescence.
The figure shows the maximum of the seismic quiescence prior to the 2016 Kumamoto Earthquakes.
