Estimation of Seismic Centroid Moment Tensor Using Ocean Bottom Pressure Gauges as Seismometers
TL;DR: In this article, the authors examined the dynamic pressure change at the seafloor to estimate the centroid moment tensor solutions of the largest and second largest foreshocks (Mw 7.2 and 6.5) of the 2011 Tohoku-Oki earthquake.

Tsunami Coda across the Pacific Ocean Following the 2011 Tohoku‐Oki Earthquake
TL;DR: A tsunami coda lasting more than 5 days was clearly recorded across the Pacific Ocean following the 2011 Tohoku-Oki earthquake as discussed by the authors, which is similar to that of a seismic coda in the sense that the coda energy is distributed uniformly in space.

Estimation of seismic velocity changes at different depths associated with the 2014 Northern Nagano Prefecture earthquake, Japan ( M W 6.2) by joint interferometric analysis of NIED Hi-net and KiK-net records
TL;DR: In this paper, the authors estimate the seismic velocity changes at different depths associated with a large earthquake, applying passive image interferometry to two types of seismograms: KiK-net vertical pairs of earthquake records and Hi-net continuous borehole data.

Rupture directivity, stress drop, and hypocenter migration of small earthquakes in the Yamagata-Fukushima border swarm triggered by upward pore-pressure migration after the 2011 Tohoku-Oki earthquake
TL;DR: In this paper, the authors examined a relationship between rupture propagation directions and the distribution of fault strength by analyzing seismological data from the earthquake swarm on the Yamagata-Fukushima border, NE Japan.

Stress Release Process Along an Intraplate Fault Analogous to the Plate Boundary: A Case Study of the 2017 M5.2 Akita-Daisen Earthquake, NE Japan
Keisuke Yoshida,Taka'aki Taira,Yoshiaki Matsumoto,Tatsuhiko Saito,Kentaro Emoto,Toru Matsuzawa +5 more
TL;DR: In this paper, stress accumulation and release in the crust remains poorly understood compared to that at the plate boundaries, and spatiotemporal variations in foreshock and aftershock activities can provide key con...
