This report discusses the seismic problem of Puerto Rico and describes the objectives, design, and implementation of the comprehensive Puerto Rico Seismic Program. This program is managed and conducted by the U.S. Geological Survey for the Puerto Rico Water Resources Authority (PRWRA). The principal objective of the program is the rapid assessment of regional and local seismicity of Puerto Rico and the associated seismic hazard.
The principal objectives of the South Carolina Seismic Program are to: (1) provide essential high-quality raw seismic data for earthquakes in South Carolina; (2) compute accurate estimates of event and source parameters; (3) provide a catalog of events and source parameters that will be used in further evaluation of seismic hazard; and (4) respond with rapid estimates of event parameters if a large event occurs within South Carolina during the duration of the program.
A new seismological project is now underway in Puerto Rico to provide information needed for accurate assessment of the island's seismic hazard. The project should also help to increase understanding of the tectonics and geologic evolution of the Caribbean region. The Puerto Rico Seismic Program is being conducted by the Geological Survey with support provided by the Puerto Rico Water Resources Authority, an agency responsible for generation and distribution of electric power throughout the Commonwealth. The Program will include the installation of a network of high quality seismograph stations to monitor seismic activity on and around Puerto Rico. These stations will be distributed across the island to record the seismicity as uniformly as possible. The detection and accurate location of small earthquakes, as well as moderate magnitude shocks, will aid in mapping active seismic zones and in compiling frequency of occurrence statistics which ultimately wil be useful in seismic risk-zoning of hte island.
