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.

Wenchuan Ms8.0 earthquake coseismic slip distribution inversion

, 2015
By using GPS and gravity data before and after the Wenchuan Ms8.0 earthquake and combining data from geological surveys and geophysical inversion studies, an initial coseismic fault model is constructed.

The effect of seamount subduction on the formation of Holocene marine terraces

Earth, Planets and Space
Marine terraces have long been a subject of paleoseismology, revealing the rupture history of megathrust earthquakes. However, the crustal deformation mechanisms responsible for their formation remain inadequately explained by conventional kinematic ...

An Innovative Approach for Estimating Coseismic Surface Uplifts Using Ionospheric Observations From Remote GNSS Stations: First Application for the 2025 Myanmar Earthquake

Geophysical Research Letters, Volume 53, Issue 19, 16 October 2026.
Abstract The Mw 7.7 Myanmar earthquake on 28 March 2025 ruptured ∼480 km of the Sagaing Fault. Its fault slip distribution remains poorly constrained by three‐dimensional surface displacement data due to sparse GNSS‐coverage near the fault. Satellite‐based synthetic aperture radars capture meters of right‐lateral displacements but isolating vertical ...

The survey and mapping of sand-boil landforms related to the Emilia 2012 earthquakes: preliminary results

Annals of Geophysics, 2012
Sand boils, which are also known as sand blows or sand volcanoes, are among the most common superficial effects induced by high-magnitude earthquakes. These generally occur in or close to alluvial plains when a strong earthquake (M >5) strikes on a ...

Coseismic Shallow Slip Deficit Accounted for by Diffuse Off-Fault Deformation

International audienceEarthquake ruptures produce fault slip and kilometer-wide diffuse deformation of the host rocks. However, the origin of the diffuse deformation and its role in the rupture process are debated. We produce a refined slip model for the

The 21 August 2017 Md 4.0 Casamicciola Earthquake: First Evidence of Coseismic Normal Surface Faulting at the Ischia Volcanic Island

, 2018
On 21 August 2017, a shallow earthquake of Md 4.0 struck the CasamicciolaTerme village in the north of Ischia volcanic island (Italy). It caused two fatalities and heavy damage in a restricted area of a few square kilometers.

Sustained supershear rupture during the 2025 Mandalay, Myanmar earthquake

Communications Earth & Environment
The 2025 Mw 7.8 Myanmar earthquake ruptured the Sagaing fault, where sparse near-fault seismic observations limit source characterization. Here, we integrate optical imagery, InSAR, finite-fault slip inversion, back-projection (BP), and dynamic rupture ...
