Geothermal Energy Potential in Thailand

Major fault zones and hot springs in Thailand

Location of 50 geothermal areas in northern Thailand

More than 90 hot springs with surface temperature ranging from 400 to 1000 C are scattered throughout the country. These geothermal areas are evidently associated with granitic rocks of various ages and major faults nearby. Most of them are manifested by hot pools and seepages although some are by hot springs and geysers.

Although a number of hot springs are found in other rocks, their geographic positions are never located far beyond 25 km from granitic plutons (Ratanasthien and others, 1985). It has also been suggested that these associations limit the areas of high density as well as high potential geothermal resources to northern Thailand where almost half of the total area is covered by granites and related rocks.

Exploration results indicate the existence of potentially shallow reservoir at depth less than 200 m.
