Maha Oya Thermal Springs, also called as Maha Oya hot water springs or thermal cluster (Sinhala: මහ ඔය උණුදිය ලිං), are in Ampara District, Sri Lanka. The site is located about 2.5 km distance from the Maha Oya town.
Hot water springs
Maha Oya springs
The Maha Oya springs occur in the boundary between Highland Complex (HC) and Vijayan Complex (VC). This boundary is a sub-horizontal ductile thrust zone where a number of geologic features are identified. They include major mineralization occurrences such as magnetite, serpentinite, gold, corundum and calcite as well as formations of hot water springs (Widanagamage, 2011). There are seven out flowing hot water wells at the Maha Oya springs site. The average temperature of the hottest well is about 58°C while the lowest is 38°C (Adikaram & Dharmagunawardhane, 2013).
