TL;DR: In this paper, centroid moment tensors of earthquakes that occurred from 2003 to 2011 in and around the focal area of the 2011 Mw 9.0 megathrust earthquake in eastern Japan were estimated.

TL;DR: In this paper, the authors observed temporal change in the stress field of the upper plate associated with the Tohoku-Oki earthquake, indicating that strain accumulation is possible even in the near-trench area at shallow depths.

TL;DR: The MOWLAS as discussed by the authors (Monitoring of Waves on Land and Seafloor) is a land and seafloor data collection system developed by the National Research Institute for Earth Science and Disaster Resilience (NIED).

TL;DR: Yoshida et al. as mentioned in this paper estimated the stress fields in inland areas of eastern Japan before and after the 2011 Tohoku-oki earthquake by inverting focal mechanism data, and they found that the stress field did not change in central and south-central Japan after the earthquake.

TL;DR: Ocean-bottom monitoring of offshore seismicity off southern Kyushu, Japan, recorded a complete episode of low-frequency tremor, lasting for 1 month, that was associated with very-low-frequency earthquake (VLFE) activity in the shallow plate interface, suggesting that both the shallow and deep tremor and VLFE may be triggered by the migration of episodic slow slip events.
