The effect of seamount subduction on the formation of Holocene marine terraces
Earth, Planets and SpaceMarine 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 ...

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 ...

, 1999 International audienceWe study the effect of a superficial layer overlying a half-space on the surface displacements created by a dip-slip dislocation on a planar rectangular fault using a 2-D finite element model. The effect of the density and Poisson’s

Impact of topography on coseismic modeling and earthquake static slip inversions
, 2020 After an earthquake occurs, slip models of the event may be produced by inverting geodetic data for slip on a finite fault. This process generally requires coseismic Green's functions, which must be calculated in advance.

Sustained supershear rupture during the 2025 Mandalay, Myanmar earthquake
Communications Earth & EnvironmentThe 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 SciencesAn 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 ...

, 2019 Field studies characterized early on natural faults as rough, i.e. non-planar at all scales. Fault roughness induces local stress perturbations, which dramatically affect rupture behavior, resulting in slip heterogeneity.

Material point method for large deformation analyses of coseismic landslides
, 2021 Estimation of coseismic landslides is of particular importance for seismic hazards assessment and mitigation strategies. To realitically and efficiently simulate the complete landslide process during earthquake from triggering to post-failure large ...

Crustal deformation in Hong Kong: Insights from GNSS observations and geophysical models
International Journal of Applied Earth Observations and GeoinformationThis 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
