NCEI’s account, from the sources it cites.

The earthquake caused damage from Bocas del Toro, Panama, to Batan and Turrialba, Costa Rica (Bermudez Leon, 2000). There were landslides in the Cordillera de Talamanca and minor damage in Valle Central. The PDE (1991) reported that landslides blocked roads between Limon and central Costa Rica. Earthquake also felt in Nicaragua and Honduras, and on San Andres Island, Colombia. Maximum uplift of 1.4 meters was observed near Limon and sandblows and liquefaction caused subsidence of soils in the Bocas del Toro area. Ground cracks also occurred in the epicentral area. About 10,000 were homeless from the destruction. A tsunami was generated from this event.
