The Puerto Rico Strong Motion Program (PRSMP) has 114 strong motion stations and 21 seismically instrumented structures in five (5) countries. This paper explains how the PRSMP has been able to recover from the detrimental effects of Hurricane María to become a more robust, strong motion network in terms of instrumentation with 100% of the data loggers with recent technology, in terms of energy with 48/90 (53%) of the free field stations in the Island with photovoltaic systems, and in terms of communication with 51/90 (57%) transmitting its data real time and developing two data centers. In addition, the southwest Seismic Sequence, with its main event on January 7, 2020, has allowed the increment of strong motion stations and the improvement of its communication in the region that covers from Ponce to Mayagüez.

Synthetic strong motion records for the 1991, Mw 7.6, Limon, Cosa Rica earthquake were computed for several hundred different source models. The rotd50 parameter was used to compare synthetic and observed data at seven stations that recorded the event. The source model that minimized the misfit was selected to calculate new synthetic records at present-day stations. The result indicated that the fault length reached some 100 km long by 40 km deep. The largest peak ground acceleration would have been recorded in the stations located along the Caribbean coast, close to the epicenter. A post-earthquake bridge inspection calculation using our scenario earthquake predicted a high level of damage to several bridges that collapsed in 1991.

Synthetic strong motion records for the 1991, Mw 7.6, Limón, Cosa Rica earthquake were computed for several hundred different source models. The rotd50 (response spectra) was used to compare synthetic and observed data at seven stations that recorded the event.
