Parker volcano (also known as Falen locally) is a low, but steep-sided vegetated stratovolcano located 30 km west of General Santos City, near the southern tip of Mindanao Island, Philippines. The andesitic-dacitic volcano contains a 2.9 km diameter summit caldera with a lake, Lake Maughan (2 km diameter). Parker was recently identified as the source of a major explosive eruption in 1641, which caused devastating pyroclastic flows and lahars, and heavy ash fall and darkness over Mindanao Island. The 1641 eruption was one of 3 large explosions of Parker volcano within the past 3800 years. It created the present-day summit caldera. The eruption style of Parker volcano is similar to Pinatubo volcano, which had a Plinian eruption in 1991.
