✓Accepted Answer

The Kanniya Hot Springs (situated 8km west of Trincomalee) comprise seven shallow square masonry wells enclosed by a low wall. Geological surveys indicate the thermal waters originate from deep meteoric water circulation descending through fractured Precambrian Highland Complex gneiss along active regional fault lines, where geothermal heating warms water temperatures between 35°C and 42°C. The varying temperatures across the seven adjacent wells are caused by differing subterranean mixing ratios between rising thermal mineral spring water and cool shallow local groundwater aquifers.

Hindu mythology attributes the wells to King Ravana, who struck the earth with his sword during funeral rites for his mother, releasing subterranean thermal streams.
