Measuring ground displacements from SAR amplitude images: Application to the Landers Earthquake [PDF]

open access: yes, 1999
ERS SAR amplitude images are utilized to map ground displacements from a sub‐pixel correlation method. It yields a ground two‐dimensional displacement field with independent measurements about every 128m in azimuth and 250m in range. The accuracy depends

Fault Kinematics of the 2019–2026 Puerto Rico Earthquake Sequence: Conjugate Faulting Within a Zone of Oblique Subduction

open access: yesJournal of Geophysical Research: Solid Earth, Volume 131, Issue 3, March 2026.
Abstract The 2019–2026 southwestern Puerto Rico earthquake sequence has the characteristics of an earthquake swarm with over 9,000 events of Mw 2.5 or greater over an area of 1,500 km2, and the largest event is an Mw 6.4 on 7 January 2020. Previous studies have proposed two structural interpretations: (a) an E‐striking, N‐dipping normal fault hosting ...

Interseismic strain accumulation: Spin-up, cycle invariance, and irregular rupture sequences [PDF]

open access: yes, 2006
Using models of infinite length strike-slip faults in an elastic layer above linear viscoelastic regions, we investigate interseismic deformation. In the models we investigate, interseismic strain accumulation on mature faults is the result of the ...

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

open access: yesEarth, 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

open access: yesAnnals 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 ...

Triggered seismicity associated with the 1990 Nicoya, Costa Rica, M-w=7.0 earthquake [PDF]

open access: yes, 2009
The 25 March 1990 (M-w = 7.0) subduction megathrust earthquake that occurred offshore the Nicoya Peninsula, Costa Rica, produced a large number of aftershocks on the subduction plate interface as expected and preceded an unusual sequence of earthquakes ...

Energy partitioning during an earthquake [PDF]

open access: yes, 2006
We investigate the partitioning of energy released during an earthquake to radiated, fracture and thermal energies in an attempt to link various observational results obtained in different disciplines.

Improving InSAR geodesy using global atmospheric models [PDF]

open access: yes, 2014
Spatial and temporal variations of pressure, temperature and water vapor content in the atmosphere introduce significant confounding delays in Interferometric Synthetic Aperture Radar (InSAR) observations of ground deformation and bias estimatesof ...

Stability Analysis of GNSS Stations Affected by Samos Earthquake

open access: yesApplied 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 ...
