Seismograms of the Guadeloupe earthquake of March 26, 2021 recorded by the Resif-Epos stations of the Antilles

An earthquake of magnitude 6 occurred during the night of 25 to 26 March in Guadeloupe, at 4:51 Paris time and 0:51 local time. After analysis by an operator, the website of the National Seismic Monitoring Network confirms the magnitude and locates the epicenter about 100 km northeast of the main island, at a depth of about 18 km (2 km uncertainty). This figure shows the seismograms of the earthquake, recorded by the Resif-Epos stations located in the Antilles near the epicenter and published on the BCSF-Renass website. The code appearing above the beginning of the recording indicates first the network. GL stands for Observatoire volcanologique et sismologique de Guadeloupe (OVSG) and WI for West Indies French Seismic Network, both operated by IPGP. These two letters are followed by the station code. The distance to the epicenter is indicated below. The French seismological and geodetic network Resif is a national research infrastructure dedicated to the observation and understanding of the structure and dynamics of the Internal Earth. Resif is based on high-tech observation networks, composed of seismological, geodetic and gravimetric instruments deployed in a dense manner throughout France. The data collected make it possible to study with high spatial and temporal resolution the deformation of the ground, surface and deep structures, seismicity on a local and global scale and natural hazards, and more particularly seismic events, on French territory. Resif is part of the European (Epos - European Plate Observing System) and global systems of instruments used to image the Earth's interior as a whole and to study many natural phenomena.
