Invitation to the one day Workshop on Earthquake and Stress

We plan to have a one day workshop on “earthquake and stress” just prior to the RS2013, sponsored by KANAME and RS2013.

KANAME: Research project on super deep drilling to seismogenic zone in Japan

After the 2011 Tohoku M 9.0 earthquake, numerous studies from the analysis of seismological, geodetic data and numerical simulations have been reported. From these studies, we have been recognizing the role of stress (stress level before the earthquake, stress drop, pore pressure distribution and evolution) as one of the key parameters for large earthquake generation.
   In the meantime, there are several seismogenic zone drilling programs, which may potentially enable us to reach to rupture zone and recover fault materials and make in-situ measurements and long term monitoring. The studies with remote data urges the scientists and engineers community to seriously establish strategy for and re-examine the necessity of for in-situ stress tests under seismogenic zone drilling programs to better understand earthquake generation.
   We have to note that remote seismological and geodetic observations have great advantages over in situ measurements, because they give us information on wide range of space-time frame, where as in situ measurements are limited to very few measurements.
   In the mining applications, it is crucial to control earthquake generation not only to “understand” them from scientific “curiosity”. The research in South Africa is one of the good examples of such purposes, where integrated studies with in-situ measurements and monitoring, numerical simulations and laboratory experiments have been pursued to reduce seismic hazard. Triggered earthquake issue in several applications is also the case.
   During this workshop, we expect enthusiastic presentations and discussions on the following topics;

# Reviews of the Tohoku earthquake and other large earthquake, earthquake cycle model
# Integration of numerical simulation, in situ measurements and laboratory experiments
# Evidences to show the role of stress by in-situ observations and laboratory experiment
