Slip History for Short-Term Slow Slip Events With Low

Slow slip events (SSE) which coincide with nonvolcanic deep low-frequency tremor have been detected in southwest Japan subduction zone (Obara et al., 2004). This coupling phenomenon has similar characteristics to the similar to the episodic tremor and slip (ETS) in the Cascadia subduction zone (Rogers and Dragert, 2003). The SSEs have been found not only in the western Shikoku region (Obara etGet price

Monitoring of coupling distribution and small Short-term SSEs

In the south-western part of Japan, there occur episodic tremor and slip beneath Nankai trough. These short-term slow slip events (S-SSEs) especially in Tokai region are known to be very small and hard to detect by GPS. Our study is a trial for monitoring these S-SSEs by GPS data. We applied geodetic inversion to three dimensional daily GPS positioning data for 15 years from 1996 to 2010 whichGet price

Coupling and tremor rate in the transition zone around the

Especially, the coupling along the transient zones in southwestern Japan shows temporal fluctuations. The major ones are detected as long-term SSEs in the Bungo-Channel (BC) area in 1997, 2003, and 2010-11, and small fluctuations are also detected in other region along the zone.On the other hand, episodic tremors also occur in the transient zone.Get price

Temporal change in plate coupling and long-term slow slip

Dec 01, 2015 · After the long-term SSE terminates, the interplate coupling rapidly recovers to the full coupling. Although three long-term SSEs in 1997, 2003, and 2010 released part of the stress accumulated by the interplate coupling, the effect of the SSEs was limited and the entire Nankai area including the SSE patch has continued to experience stressGet price

Recurrent slow slip event reveals the interaction with

It remains enigmatic how slow slip events (SSEs) interact with other slow seismic events and large distant earthquakes at many subduction zones. Here we model the spatiotemporal slip evolution of the most recent long-term SSE in 2009-2011 in the Bungo Channel region, southwest Japan using GEONET GPS position time-series and a Kalman filter-based, time-dependent slip inversion method.Get price

Reexamination of the interplate coupling in the Tokai region

Dec 21, 2004 · Our results clearly show that the maximum of the SSE and back‐slip do not overlap each other for the present event. However, the largest forward slip region (approx. 3.0 cm/yr) corresponds to moderate coupling (approx. 1 cm/yr) region in 1997–2000.Get price

Possible Long-term SSEs in the Tokai Area, Central Japan

The long-term slow slip event (LSSE) in the Tokai area, central Japan, from mid-2000 to mid-2005 [Suito and Ozawa (2009)], had continued five years, which was much longer than other LSSEs around the world [e.g. Schwartz and Rokosky (2007)]. After the termination of the SSE in 2005, no obvious long-term SSE was detected and that makes difficult to discuss a recurrence interval of the events. InGet price

Integration of transient strain events with models of plate

SSE and tremor are not always linked, for example, in Hawaii and New Zealand, repeating SSEs are accompanied by microseismicity but not any detectible tremor (Segall et al. 2006; Delahaye et al. 2009; Montgomery-Brown et al. 2009). In southwest Japan, there is a strong coincidence between S-SSEs, tremor, LFE and VLF (Ito et al. 2007).Get price

In deeper areas of the plate boundary, back-slip rates are decreasing and cease to exist at depth of 30–40 km. This depth corresponds to the transition zone of the interplate coupling. 3.2.

Predicting the geodetic signature of MW 8 slow slip events

Estimation of interplate coupling in the Nankai trough, Japan

In SW Japan, both horizontal and vertical crustal motion seem to be consistent with the back-slip model prediction (Aoki Scholz 2003; Heki 2007).
