| Outline of Final Research Achievements |
I successfully estimated a detailed seismic attenuation structure beneath Hokkaido. The characteristics of the obtained attenuation structure is almost the same trend in the seismic velocities structure by Kita et al. [2012, JGR]. I also estimated stress drops of intraslab earthquakes beneath Hokkaido, which promotes the understanding the cause of the intraslab earthquakes. I can also estimated a seismic attenuation structure beneath southwestern Japan, using my study experience beneath Hokkaido. Finally, three papers are published using this science fund.
