Modulation of Slow Slip Event Characteristics Throughout the Costa Rica Subduction Zone Earthquake Cycle

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Slow slip events (SSEs) represent an aseismic transient slip mode that repeats quasi‐periodically, near or partially overlapping with the megathrust earthquake zone. However, the process of stress interaction between SSEs and earthquake zones is not clearly understood.

Coseismic Effects Following Petrinja 2020 Earthquake

, 2021
Potres na području grada Petrinje koji se dogodio u prosincu 2020. godine, uzrokovao je, osim ljudskih žrtava i značajne materijalne štete, brojne geološke pojave različitog tipa na širem potresom zahvaćenom području. Među njima su najznačajnije pojave

Investigating Postseismic Creep in the Laboratory: Testing Dislocation‐Based Models for Transient Creep in the Upper Mantle

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Studies of postseismic creep often infer a strong reduction in upper‐mantle viscosity after large earthquakes, yet the microphysical mechanism responsible for this behavior remains subject of debate. Here, we present new gas‐medium apparatus experiments at 1100–1200°C on pre‐dried, annealed Åheim dunite (grain size of 400 μ ${\upmu }$m ...

Coherence Difference Analysis of Sentinel-1 SAR Interferogram to Identify Earthquake-Induced Disasters in Urban Areas

Remote Sensing, 2018
This study proposes a workflow that enables the accurate identification of earthquake-induced damage zones by using coherence image pairs of the Sentinel-1 satellite before and after an earthquake event.

Decadal Creep Acceleration on the Northern Japan Trench Driven by Erosion of Heterogeneously Locked Asperities

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Geodetic and seismic observations before the 2011 Mw 9.0 Tohoku‐oki earthquake indicate decadal‐scale acceleration of aseismic slip along the northern Japan Trench, but the mechanism remains debated. We show that this transient can be explained by creep‐front propagation that progressively erodes heterogeneously locked asperities.

Coseismic Effect of the 2025 Kamchatka Earthquakes

Russian Journal of Earth Sciences
We investigate the conditions under which coseismic electromagnetic disturbances arise, caused by the propagation of elastic waves from distant earthquakes with magnitudes ranging from 6.9 to 8.7.

Multi‐Scale Growth of an Mw 7.0 Earthquake via Hierarchical Cascading Rupture From an Mw 3.8 Repeating Event

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract To understand what governs earthquake size, we investigated the 2021 Mw 7.0 Japan Trench earthquake, which began near a nest of repeating earthquakes. High‐precision hypocenter relocation and P‐waveform correlation show that the mainshock initiated nearly identically to Mw 3.8 repeaters.

Cessation of Nearby Low‐Frequency Earthquake Activity Following the December 2024 Mw 7.0 Mendocino Earthquake: The Likely Role of Pore Pressure Reductions

Geophysical Research Letters, Volume 53, Issue 20, 28 October 2026.
Abstract Earthquakes affect surrounding fault systems through multiple mechanisms. Here, we examine a rare cessation of activity in 27 families of low‐frequency earthquakes (LFEs) that likely reflect fault creep at the southern edge of Cascadia subduction, near the Mendocino triple junction.
