Geophysical and Sea level data availability in Puerto Rico

The Puerto Rico Seismic Network (PRSN) and the Puerto Rico Strong Motion Program Network (PRSMP) form the PR network, the regional authority for seismic activity in Puerto Rico and Virgin Islands. The mission of the PR network is to monitor and rapidly determine the location and size of all earthquakes and to support the Tsunami Service Provider (PTWC) to determine the Tsunami alert level in the Area of Responsibility (AOR), and to disseminate this information to concerned agencies and stakeholders, media, scientists, and public. The PR network compiles and maintains an extensive seismic database of earthquake parameters, continuous waveforms (ground motion and sea level) and their effects which serve as a foundation for geoscience & oceanographic research in the region. The network also conducts education and outreach to the local population to mitigate the impact of a significant earthquake or tsunami.

With funds from both local and federal sources, the Puerto Rico Seismic Network, staffed 24/7 since March 2008, has been expanding its operations for both regional earthquake monitoring and tsunami early-warning. The integrated network consists of 22 broadband, 6 intermediate, and 4 short periods seismic stations, 15 permanent GNSS stations one of which is equipped with Trimble's RTX capability, and 17 tide gauge stations. A GSN station is also located in Cayey, Puerto Rico. The PR network also operates more than 100 free-field, 1-4G, strong motion stations throughout Puerto Rico, the Virgin Islands and Dominican Republic. The GPS stations are co-located with broadband and strong motion sensors and closely-spaced with tide gauge stations.

The PR network is currently in the process of digitizing 30 years of analog seismograms, continuous data from 2002 onward and from 1987 >45k parametric data from earthquake events are in the database; between 1992 to 2002 only event triggered digital data was collected. Geodetic data is available from 2012 and sea level data is available from 2006. All the PR data are available via RT connectors like seedlink or EW/export. The goal of this abstract is to describe the PR data set, including the real time earthquake and tsunami monitoring and data sharing as well as the specific protocols used to broadcast earthquake/tsunami messages; regional cooperation will be also discussed.
