Finding Seafloor Faults Linked to Puerto Rico Earthquake

Map of the portion of the southwest coast of Puerto Rico affected by an earthquake sequence that began in December 2019, along with portions of the seafloor where faults involved in the earthquake sequence were suspected to exist. (A related image shows indications of seafloor faulting found on a USGS seismic research cruise led by USGS research geophysicist Uri ten Brink

Scientists find signs of undersea faults off SW Puerto Rico

Locations of multichannel seismic reflection profiles (in black), collected during cruise FA2020-14. The profiles are overlain on colored and shaded multibeam bathymetry, Lidar topography (green and white) and near-shore bathymetry (darker blue), and NOAA coastal relief model (light blue and white). Dashed purple lines – hypothesized faults from the distribution of

When wetland plants in the northeast emerged this spring, USGS scientists were working from home and unable to start many planned research activities. However, many instruments were already deployed and continued to collect information critical to USGS research. These instruments still need visits occasionally to download data and make sure there aren’t any problems.

Regional Map of Puerto Rico

Regional map of Puerto Rico. Less than two months after the largest earthquake in the seismic sequence, the USGS Woods Hole Coastal and Marine Science Center organized a rapid response seismic survey. The goal of the survey was to map the faults which ruptured during the seismic activity and understand the regional context and potential for other earthquake activity in the
