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 ...

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 ...

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 ...

Stability Analysis of GNSS Stations Affected by Samos Earthquake

Applied Sciences
An earthquake cycle can cause meters of displacement on the surface and at Global Navigation Satellite System (GNSS) stations. This study focuses on the identification of GNSS stations that have significant displacement because of a Mw 7.0 earthquake ...

Crustal deformation in Hong Kong: Insights from GNSS observations and geophysical models

International Journal of Applied Earth Observations and Geoinformation
This study investigates crustal deformation in Hong Kong using the Global Navigation Satellite System (GNSS) observations from 19 stations and a range of geophysical models. We examine horizontal and vertical land motions (VLM) recorded by GNSS from 2001

A research framework for seismic slip distribution inversion considering atmospheric effects and deformation field downsampling

International Journal of Digital Earth
Traditional Interferometric Synthetic Aperture Radar (InSAR) methods have difficulties in capturing deformation information of small and medium-sized earthquakes due to small surface deformation and atmospheric interference.

Unlocking the hidden secrets of the 2023 Al Haouz earthquake: Coseismic model reveals intraplate reverse faulting in Morocco derived from SAR and seismic data

International Journal of Applied Earth Observations and Geoinformation
The 2023 Mw 6.8 Al Haouz earthquake struck Morocco’s Atlas Mountains on September 8, causing over 3000 fatalities and extensive damage, revealing hidden seismic hazards in this slowly deforming region. Despite its impact, Al Haouz earthquake has received
