The Puerto Rico Strong Motion Program – a State of the Art and Records Obtained During the m6.4 January 7, 2020 Earthquake
Description:
The Puerto Rico Strong Motion Program (PRSMP), under the Department of Civil Engineering and Surveying of the University of Puerto Rico at Mayaguez (UPRM) has as primary objectives to minimize the loss of life and economic losses caused by high-intensity earthquakes in the Puerto Rico region. The PRSMP is made up of two main components. First, a network of 129 strong motion stations in Puerto Rico (100), the Dominican Republic (17), the British Virgin Islands (10), US Virgin Islands (USVI) (1), and Anguilla (1) and second, a network of Instrumented Structures that includes dams, buildings, bridges and a control tower.
The strong motion stations (sms) within Puerto Rico and the USVI consists of 70 (69%) Obsidian data loggers and 31 Etna2 (31%) for a total of 101 stations. Each sms has its own global positioning system (GPS). 68% is energized by means of a photovoltaic system; 23% have backup electric generators, and the remaining 9% depend on the Electric Power Authority and their own backup battery. In relation to communications, 51% of the stations are transmitted through Modem Cellular, 12% through microwaves, 12% through private Internet, 17% transmit data through combinations of microwaves and modems cellular or private internet and the remaining 8% are just stand alone stations. The data is transmitted both to the Primary Data Center in the Civil Engineering building on the UPRM Campus and to the Secondary Data Center located inside a bunker at Finca Montana in the town of Aguadilla that was part of the former Ramey Military Base. The data is sent to both the United States Geological Survey (USGS) and the Puerto Rico Seismic Network (PRSN), under the Department of Geology of UPRM who are in charge of sending the data to IRIS. It should be noted that 23% of sms have a Vs30 study performed. Over 40 records of the M6.4 January 7, 2020 EQ can be obtained at https://prsmp.uprm.edu/M6-4/.
