Moment Tensor Solution derived by W-phase Source Inversion
Following is the Moment Tensor Solution derived by W-phase Source Inversion using waveform data recorded in regional scale. This method is developed by Kanamori and Rivera (2008).

Waveform recorded in the Earthquake Data Sharing system
In the Center for Geophysical Observation and Instrumentation, ERI, we provide earthquake data observed in the Kanto and Koshinetsu area, Kii peninsula and surrounding area and the western Seto Inland sea as a regional center of observational research for earthquake prediction.
