RESUMEN
On the ocasion of the Spitak earthquake (December 7, 1988) irregularities in several geophysical and geochemical parameters were revealed. In this paper data on anomalies in the water level in deep wells and in the helium content in thermal waters are presented. Data were collected from sites located in Georgia. The presented anomalies can be attributed to the processes that preceded and accompanied the earthquake; the presence of a time delay in the onset of the helium content anomalies at different sites could be an indication of the stress propagation.(AU)
