| Description |
The Puerto Rico Trench (PRT) poses major earthquake and tsunami hazards. Tsunamis generated at this subduction zone may also impact the U.S. East Coast. This project supports land and sea seismic experiments across the PRT and Puerto Rico. The experiments will define the detailed seismic structure of the PRT, advance our understanding of the PRT, and improve hazard assessment. The project consists of: (1) Three wide-angle seismic reflection/refraction profiles using ocean bottom seismometers (OBS); (2) Seven multichannel seismic (MCS) reflection profiles, two parallel to and inland from the trench, and five across the trench. (3) An array of 100 short-period land nodal seismometers deployed across the Puerto Rico island. The project will provide support for training several graduate students and an early career scientist, as well as research opportunities for faculty and students at a minority serving institution. |
