“Episodic tremor and slip, inland and in-slab seismicity on the Kii Peninsula, Japan.” -- by Dr. Saeko Kita, UC Berkeley
We examined time variations in seismicity rates, b-values, and stress regimes in the slab associated with times of episodic tremors and slip (ETS) during 17 years beneath Kii peninsula. At 1 month before the ETS times, seismic rate and b-value become high, which is similar to characteristics of fluid-induced seismicity. Sigma 1 axis in the oceanic crust beneath the ETS zone rotated larger than that updip of the zone just after the ETS times. The results show that monitoring of in-slab earthquakes would be a new technique to detect time change of plate coupling degree and slow slip events.
