Tectonics, Volume 45, Issue 3, March 2026.Abstract Earthquakes in intraplate regions are often scattered and difficult to associate with specific geological structures, requiring detailed surveys to identify active faults. Improving knowledge of local seismicity in these areas is essential for accurate seismic hazard assessment and for safe planning of economic activities that could affect ...

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Frequency‐dependent seismic velocity variations (dv/v) provide depth‐resolved constraints on aquifer behavior under groundwater fluctuations. We analyze 17 years of dv/v time series from ambient noise interferometry in the Chiang Mai Basin, Thailand, and observe contrasting dv/v behavior below and above 1 Hz. By integrating GPS, meteorological,

Video camera and seismic monitoring of water bulge explosion at Strokkur Geyser, Iceland
VolcanicaEruptions of volcanoes and geysers share many fundamental similarities: for example, they are manifestations of Earth’s geothermal energy, involving the pressure-driven expulsion of fluids from the Earth’s interior.

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Pulse‐like infrasound accompanying volcanic phenomena sometimes suggests interaction with water at the crater. We focus on pulse‐like infrasound observed at Semisopochnoi Island in the Aleutian Arc, Alaska, during the phreatomagmatic activity on 13 July 2021.

Chigaku Zasshi (Jounal of Geography), 2008 Andrija Mohorovicic (1857-1936) is a world-famous Croatian geophysicist and the discoverer of the Earth's crust/mantle boundary known as the Moho-discontinuity. The historical seismometer used by A. Mohorovicic to detect the Moho in 1909 is still maintained in working conditions, and is displayed in the Department of Geophysics of the University of ...

Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract The Laguna del Maule volcanic field in Chile has been uplifting at exceptional rates since 2007, offering a unique opportunity to examine the interplay between crustal deformation and magma dynamics. To understand this relationship, we integrate GNSS with local seismic observations from 2013 to 2024 to model the reservoir strain field ...

Tide‐Modulated Ocean‐to‐Earth Energy Conversion Quantified With Coastal Fiber Sensing
Geophysical Research Letters, Volume 53, Issue 4, 28 February 2026.Abstract Quantifying how incident ocean waves transfer energy into seismic surface waves along the nearshore is essential for understanding coastal hazards and Earth–ocean coupling, yet time‐resolved in situ estimates have been scarce. Here we use a beach‐deployed distributed acoustic sensing array co‐located with an ocean‐bottom node to directly ...
