Seismotectonics

Using methods from a variety of geophysical fields, such as geoelectromagnetism, the heterogeneous structures in the regions of the subduction plate boundary and the lower crust of inland areas are investigated to improve the understanding and evaluation of long-term earthquake occurrences. Recent investigations include:

1) Studies of crustal heterogeneity around earthquake source regions and active faults to improve long-term evaluations of earthquake occurrence.
2) Studies of the regional and global conductivity structure of the Earth’s interior.
3) Studies on the recovery process of the Nojima fault following the Kobe earthquake.
