What type of plate boundary was the Japan earthquake of 2011? What are the major tectonic plates? Which three tectonic plates are found along the Prime Meridian? What boundary is between the Nazca Plate and the Pacific Plate? What is the largest tectonic plate called?

The August 8 event took place on theNankai subduction zone: here, the Philippine Sea plate creeps below Japan, which is attached to the Eurasian plate. This type of plate boundary is the sort capable of producing ‘megaquakes’, those of amagnitude-8.0 and higher. (The numerical difference ...
Rupture of the plate boundary fault during the 2011 Tohoku-oki earthquake with moment magnitude 9.0 is thought to have propagated to the trench. Surface exposure of the fault has not yet been confirmed because of great depths that are challenging to access and study. Using a manned submersible ...

Stratigraphy of event deposits along the Japan Trench is expected to provide spatial and temporal information related to plate boundary megathrust earthquakes as the 2011 Tohoku-oki earthquake. Evidence of historical and prehistorical huge earthquakes has often been found as onshore tsunami deposits (e...
The most important factors for the tectonics are the deformations of the subductive boundary around the triple junction for retention of the minimum curvature of subduction of the thick Pacific Plate along an irregular boundary with an uncinate process, created by the retreat of the Izu Trench on...
3). The upper boundary of the Shimajiri Group in the offshore Okinawa 1 − x well (> 5.53 Ma) is at least 3.5 Myr older than that on Miyako Jima and off its eastern coast and Okinawa Jima (ca. 2 Ma). Considering the transition from a siltstone-dominant lithology to a ...
We suggest that the thrust faults clearly imaged in the trench axis acted as the shallowest plate boundary megathrust during the Tohoku earthquake, and caused the large shallow slip proposed by seismological studies and seafloor displacement observed by the differential bathymetry. The high pore ...
A pipe is covered with a guard pipe to maintain the cool- ant level within the RV with no coolant leak into the con- tainment vessel (CV), even if a guillotine break is assumed for the primary coolant boundary piping in the frame of beyond design basis events (BDBEs). The volume ...
