On 14 August 2021, the moment magnitude ( M w ) 7.2 Nippes earthquake in Haiti occurred within same fault zone as its devastating 2010 7.0 predecessor, but struck country when field access was limited by insecurity and conventional seismometers from national network were inoperative. A of citizen installed 2019 provided near-field data critical to rapidly understand mechanism mainshock monitor aftershock sequence. Their real-time defined two clusters that coincide with areas coseismic slip...
Summary The central Pamir plateau moves northward and collides into Eurasia at a rate that varies significantly over its 600 km-wide extension. However, the active structures accounting for such internal shear strain remain enigmatic. In this study, we use Interferometric Synthetic Aperture Radar (InSAR) data to investigate coseismic postseismic deformation of ${M}_w6.9$ Sarez earthquake on 23 February 2023. Using Bayesian framework, find most likely seismogenic fault geometry explore full...
The plate boundary between the Caribbean and North American plates exhibits a striking-complexity significant width with multiple microplates moving relative to each other, resulting in seismic hazard on island of Hispaniola. This region has experienced several major earthquakes recent decades, particularly along left-lateral fault systems Enriquillo-Plantain Garden (EPGF) Septentrional-Oriente faults. These accomodate eastward motion at rate approximately 20 mm/year. oblique convergence...
Large continental strike-slip earthquakes usually present a complex rupture trace composed of several segments separated by discontinuities. Fault geometry may interact with stress concentration and propagation have an influence on the distribution coseismic slip termination ruptures. However, other factors can propagation, such as rheology fault bulk, which be affected crustal damage from earthquakes, initial state, notably depends history. Here we characterize these interactions in case...

Abstract On 14 August 2021 the Mw 7.2 Nippes earthquake struck southern Haiti, rupturing a segment of Enriquillo‐Plantain Garden Fault system (EPGF), 300 km‐long strike‐slip fault that accommodates half highly oblique convergence displacement between Caribbean and North American plates. We use coseismic surface displacements from Interferometric Synthetic Aperture Radar Global Navigation Satellite System (GNSS) to estimate geometry rupture through systematic parametric exploration, determine...
Over the past two decades, InSAR evolved from occasional processing of single interferograms over arid terrains to monitoring continuous time series SAR acquisitions at continental scale. Challenges, including atmospheric phase screen mitigation, automatic careful image co-registration, ionospheric corrections, or discontinuous acquisition planning, were met through various technical and methodological advances by many research groups globally. The resulting methodologies now allow us a vast...
