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.

Mount Cagua, a 1133-m-high stratovolcano, lies just below and to the left of the center of this NASA Space Shuttle image. Palui Island lies off the tip of the peninsula, which forms the NE tip of Luzon and is about 30 km wide at its broadest point. Cagua, locally known as the "Mountain of Fire," has a circular summit crater 1.5 km in diameter. Its only known historical eruption consisted of a phreatic explosion in 1860 that may have been accompanied by a pyroclastic flow. Thermal areas are located on the NW to NNE flanks.

The northernmost active volcano in Luzon is Mount Cagua, a 1133-m-high stratovolcano at the NE tip of Luzon. 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.
