Red Sísmica de Puerto Rico: Seismic Safety & Preparedness

The Red Sísmica de Puerto Rico Seismic Network (PRSN), established in 1976 through a cooperative agreement between the University of Puerto Rico and the United States Geological Survey (USGS), plays a pivotal role in monitoring seismic activity in Puerto Rico and the surrounding regions. With a mission dedicated to providing crucial seismic information and promoting earthquake and tsunami preparedness, questions like “¿Hubo un temblor hoy?” are addressed promptly by PRSN, ensuring the community stays informed and prepared. This network’s significance underscores the importance of real-time data for safety and awareness in earthquake-prone areas.

Operating an extensive network of seismic stations across Puerto Rico and the Virgin Islands, the PRSN, affiliated with the Department of Geology at the University of Puerto Rico at Mayagüez, not only offers real-time seismic data but also enriches educational and research opportunities in the field of geology. Staffed by a team of seismologists, geophysicists, engineers, and educators, Red Sísmica de Puerto Rico efforts are fundamental in promoting comprehensive earthquake and tsunami preparedness among the local communities. As part of the National Tsunami Hazard Mitigation Program (NTHMP), PRSN’s work is crucial in enhancing safety measures and public awareness regarding seismic risks in the region.

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.
