The Kriging method is documented for the first time to draw isoseismal maps of Costa Rican earthquakes. This method is recommended to replace the visual interpolation technique that has traditionally been used in Costa Rica. Kriging is demonstrated using macroseismic data from four significant events: the 6 Mw) earthquakes. Isoseismals that best fit the observed intensity data field are calculated by modeling a simple linear variogram. Earthquake effects and Peak Ground Acceleration (PGA)

The Puriscal and Bijagua earthquakes produced minor damage in the epicentral areas, where the Modified Mercalli Intensity (MMI) observed was V and VI, respectively. The Burica and Christmas earthquakes produced moderate damage in localities of the Panama-Costa Rican border region, where the MMI was VII and VIII, respectively.
