Historical Context
The establishment and evolution of the Red Sísmica de Puerto Rico Seismic Network (PRSN) have been pivotal in understanding and mitigating seismic risks in Puerto Rico and the surrounding regions. Initially installed in 1974 by the United States Geological Survey (USGS) for the Puerto Rico Electric Power Authority (PREPA), the network aimed to assess local seismicity crucial for the construction of the Aguirre and Islote nuclear power plants. This marked the beginning of a comprehensive approach to seismic monitoring in the area.
- 1974: Installation of PRSN by USGS for PREPA.
- 1987: Transfer of operation to the University of Puerto Rico in Mayagüez.
- 1997 & 2000: Modernization of data acquisition systems with IASPEI, SOUFRIERE, and ViSeis systems.
Puerto Rico’s geographical location at the boundary between the Caribbean and North American plates subjects it to frequent seismic activities. Historical records indicate earthquakes dating back to the early 17th century, with significant events shaping the island’s approach to seismic preparedness and response.
- Significant Earthquakes:
- 1670: First recorded earthquake, mainly impacting the San German area.
- 1787: An 8.0 magnitude earthquake causing extensive damage.
- 1918: A 7.5 magnitude earthquake in Aguadilla, generating a deadly tsunami.
The Red Sísmica de Puerto Rico’s continuous monitoring and data collection efforts have been crucial in understanding the seismicity of Puerto Rico and the Virgin Islands, akin to seismic activities observed in California and the Western United States. This historical context underscores the importance of the PRSN in promoting earthquake preparedness and enhancing safety measures in the region.
