Figure 4 represents the first isoseismal map (No 44 in Table 22).
It had 15 aftershocks and two foreshocks and isoseismals were drawn up (No 43 in Table 22).
Greatest intensity was reported in the surrounding area of the aftershock zone, therefore the isoseismals are distorted.
Isoseismals were drawn up Departamento de Sismologia (1990) and its focal mechanism was obtained (NEIS).

Isoseismal maps allow for the direct visualization of earthquake effects.
In Costa Rica, isoseismal lines have traditionally been drawn based on the visual interpolation of MMI data by local experts.
Although the available isoseismal maps have been carefully drawn by the interpreters, the process of drawing isoseismal lines is not standardized and the criteria used may be different from one interpreter to another.
The main goal of this study is to introduce in Costa Rica the use of an objective, homogeneous, and automatic isoseismal map drawing method using kriging interpolation, a method previously applied to seismic intensity data in Italy (Gasparini et al.
