The seismicity of the northeastern Caribbean region is monitored jointly by the Puerto Rico Seismic Network (PRSN) and the Puerto Rico Strong Motion Program (PRSMP) of the University of Puerto Rico at Mayagüez. From ten Brink, 2004
Objectives and Goals The objectives of the two networks are to record, process, analyze, and research local, regional and teleseismic earthquakes. The ultimate goals are to produce high quality data and information in order to be able to respond to the needs of emergency management and the industrial, academic and research communities, as well as the general public.
PRSN • Operation of a real time network of almost 25 short period, broad band and joint strong motion stations. • Monthly seismicity reports issued locally • Felt earthquake memos • Web site • Education and Outreach program • Puerto Rico and Virgin Islands Tsunami Warning System • Host to MIDAS • Seismological research
