Abstract We explored the submarine portions of Enriquillo–Plantain Garden Fault zone ( EPGFZ ) and Septentrional–Oriente SOFZ along Northern Caribbean plate boundary using high‐resolution multibeam echo‐sounding shallow seismic reflection. The bathymetric data shed light on poorly documented or previously unknown fault zones running over 200 km between Haiti Jamaica 300 Dominican Republic Cuba ). primary plate‐boundary structures are a series strike‐slip segments associated with pressure...
Understanding processes that may be at the origin of major earthquakes in subduction zones is highly challenging, especially case slowly converging areas. Here we compile several studies about spatiotemporal variation seismicity along boundary Caribbean plate, which evolving from westward Lesser Antilles to southward Greater and oblique collision against Bahamas platform Cuba. Analysis clusters associated with computing focal mechanisms show that:- There an increase rate cumulative seismic...
The northern margin of Hispaniola is characterised by a complex morpho-structure shaped the interplay geodynamic, tectonic, and sedimentary processes. Haiti Seismic Investigation (HAITISIS) Caribbean plate boundary reveals evidence oblique convergence. It elucidates relationships among fault-driven tectonic activity, seafloor morphology, effects transpressional deformation. markedly different morpho-structural characteristics sedimentation patterns in Eastern Western domains originated...
Transpressive deformation at the northern Caribbean plate boundary is accommodated mostly by two major strike-slip faults, but amount and location of accommodation compressional component are still debated. We collected marine geophysical data including multibeam bathymetry multichannel seismic reflection profiles along this around Hispaniola, in Jamaica Passage, Gulf Gonâve. The set allows us to image offshore active faults as well structures. confirm that Enriquillo-Plantain-Garden Fault...
Abstract Oblique convergence of the Caribbean and North American plates has partitioned strain across a major transpressional fault system that bisects island Hispaniola. The devastating M W 7.0, 2010 earthquake struck southern Haiti, rupturing an unknown fault, highlighted our limited understanding regional segmentation its link to plate boundary deformation. Here we assess seismic activity structures Haiti using data from 33 broadband stations deployed for 16 months. We use traveltime...
Abstract Volcano observatories (VOs) around the world are required to maintain surveillance of their volcanoes and inform civil protection aviation authorities about impending eruptions. They often work through consolidated procedures respond volcanic crises in a timely manner provide service community aimed at reducing potential impact an eruption. Within International Airways Watch (IAVW) framework Civil Aviation Organisation (ICAO), designated State Observatories (SVOs) asked operate...
Abstract The boundary between the Caribbean and North American plates in Hispaniola region is northwestern termination of plate subduction evolving from westward Lesser Antilles to southward Greater oblique collision against Bahamas platform Cuba. We analyze P waveforms recorded by 27 broadband seismic temporary stations deployed during Trans-Haiti project. Seismicity network June 2013 2014 used locate earthquakes. A total 514 events were identified with magnitudes ranging 1 4.5. Twenty-six...
We determine the lateral variations in seismic velocity of lithospheric mantle beneath Gulf Aden and its margins by inversion Pn (upper high-frequency compressional P wave) traveltimes. Data for this study were collected several temporary networks from global catalogue. A least-squares tomographic algorithm is used to solve lithosphere. In order separate shallow deeper structures, we use inversions shorter longer ray path data. High velocities (8.2–8.4 km/s) are observed uppermost Yemen that...
ABSTRACT Understanding the processes that may be at origin of major earthquakes in subduction zones is highly challenging, especially case slowly converging areas such as Lesser Antilles zone. Our study reveals a recorded increase seismicity rate and cumulative seismic moment over last two decades offshore Martinique island and, particularly, presumed rupture area historical 1839 earthquake. This sustained shared between extensive intermediate depth activity since 2007 Mw 7.4 earthquake...
Abstract Haiti, on the island of Hispaniola, is situated across North American‐Caribbean plate boundary at transition point between oblique subduction in east and a transform west. Here we use shear wave splitting measurements from S waves local (0–50 km) intermediate depth (50–150 earthquakes as well SK(K)S phases teleseismic to ascertain good spatial vertical resolution azimuthal anisotropic structure. This allows us place new constraints pattern deformation crust mantle beneath this...
Abstract Between 2008 and 2014, the Institut de Physique du Globe Paris (IPGP) University of West Indies, Seismic Research Centre (UWI-SRC) designed built a regional seismic network across Lesser Antilles. One goals is to provide real-time data tsunami warning centers in framework Intergovernmental Coordination Group working toward establishment other coastal hazards early system (ICG-CARIBE-EWS) for Caribbean adjacent regions (McNamara et al., 2016). In an area prone hurricanes,...
