Mount Cagua, a 1133-m-high stratovolcano, lies at the NE tip of Luzon. The circular summit crater is 1.5 km in diameter, with steep, 60-m-high walls. Basaltic-andesite and basaltic lava effusion characterized the initial stage of volcanism during the early Pleistocene. From about 600,000 to 300,000 years ago thick pyroclastic flows covered the entire volcano. Recent periods of phreatomagmatic activity have produced ash flows. The forested volcano is locally known as the "Mountain of Fire." A phreatic explosion in 1860 may have been accompanied by a pyroclastic flow. Strong solfataric activity occurred in 1907, and thermal areas are located near the summit crater and on the NW to NNE flanks. It has six hot springs. Maasok near the crater; Marafil in the northwest; Manaring, five kilometers north-northeast; San Jose, 10 kilometers north-northeast; Kabinlangan, three kilometers northwest and Paminta, two kilometers north-northwest.
