Active volcano in the Philippines
Physical features
Cabalian is classified by the Philippine Institute of Volcanology and Seismology (PHIVOLCS) as active with solfataric activity. Radiocarbon dating on a pyroclastic flow deposit from the volcano estimated that the last eruption was in 1820 +/- 30 years.[3][2]
The stratovolcano has an elevation of 945 metres (3,100 ft) with a base diameter of 8.5 kilometres (5.3 mi). The predominant rock type is andesite. Beside solfataras, other thermal features present are hot springs located on the east and west flank of the volcano. Mainit Hot Spring in the municipality of Anahawan, Southern Leyte has a temperature of 63.4–63.9 °C (146.1–147.0 °F).
Cabalian Lake
Cabalian Lake (Lake Danao) is a 500 m (1,600 ft) wide crater lake that occupies the summit crater of the volcano. The surface elevation of the lake is at 733 metres (2,405 ft). This lake is often confused with Lake Danao, which is located near Ormoc City in Leyte province.

[it] Monte Cabalían
Il Cabalían, anche Cantoloc , Cantocloc e Contodoc, è uno stratovulcano quiescente delle Filippine[1] alto 945 m.s.l.m. che sorge sulla punta sud-orientale dell'isola di Leyte non distante dalla città di San Juan, nella Provincia di Southern Leyte, nella parte centro-meridionale dell'arcipelago asiatico.
Il Cabalían è un complesso costituito di andesite con un diametro alla base di circa 8,5 km e un cratere largo 500 m nel quale si trova il lago Cabalian; le pendici sono moderatamente ricoperte di vegetazione e solcate da canaloni radiali piuttosto profondi; sui fianchi Est e Ovest del vulcano sono presenti alcune fonti termali fra cui le Mainit Springs[2]. L'attività vulcanica storica del Cabalian, attualmente di tipo solfatarico, riporta di una eruzione non meglio identificata intorno all'anno 1820.
