TL;DR: In this article, a combination of high-rate GPS data, from instruments located on the nearby islands, and a tsunami field survey was used to examine the Mentawai, Indonesia, earthquake and found that the combination of small GPS displacements and large tsunami can only explain high fault slip at very shallow depths, far from the islands and close to the oceanic trench.

TL;DR: The 15 January 2022 climactic eruption of Hunga volcano, Tonga, produced an explosion in the atmosphere of a size that has not been documented in the modern geophysical record as mentioned in this paper .

TL;DR: In this article, the authors estimated the velocity structure beneath four three-component broad-band seismic stations in the Sumatra region by the joint inversion of teleseismic receiver functions and surface wave group velocities.

TL;DR: In this paper, the authors employed a 3D velocity model and 3D wave propagation code to simulate long-period ground motions in the upper Mississippi embayment, where three simulations have been conducted on each major segment, exploring the impact of different epicentral locations and rupture directions on ground motions.

TL;DR: In this article, the authors estimated the crustal thickness and velocity structure of the Republic of Singapore's seismic network by using a linearised time-domain inversion scheme and showed that the upper-crustal high-velocity zone underlain by a velocity inversion is present across Singapore.
