The Earthquake Engineering Laboratory at the University of Costa Rica (LIS-UCR for its acronym in Spanish) started operations in 1983. That year, the United States Agency for International Development (USAID), donated several SMA-1 Kinemetrics strong-motion accelerographs to Costa Rica. They were located along the Pacific coast and the highly populated Central Valley. That was known as the Faculty of Engineering's Accelerographic Network. It was an analog network, which meant that after a strong earthquake took place, the collection and processing of the information took several days to weeks to get ready for analysis.

In 1989 the name was changed to LIS-UCR. New digital instruments were acquired and the geographic coverage of the stations increased. At the time of writing this document, the LIS-UCR has more than 160 digital, 24-bit strong-motion units located in free-field conditions, boreholes, and inside buildings. The LIS-UCR is in charge of recording, processing and storing all acceleration records for academic and research purposes. Further information can be found in: Moya- Fernández, A., L. A. Pinzón, V.
