The Colombian range of volcanic mountains contains
a remarkable regional thermal anomaly. Evidence
of this anomaly are the extended periods of magmatic
activity and the existence of numerous active and
recently active volcanoes.
Surface manifestations (hot springs, hydrothermal
eruption craters, steam vents, etc.) suggest that
there is a high probably of the occurrence of hydrothermal
systems related to these potential heat sources.
Until now, geothermal resources have been applied
in Colombia only for direct use of hot spring water
for swimming and bathing in about 38 spas from 27
