Parker volcano, Philippines
Lake Maughan occupies the steep-sided walls of the 2.9-km-wide summit caldera of Parker volcano, also known locally as Falen.
This low, vegetated stratovolcano overlooks Sarangani Bay near the southern tip of Mindanao Island and is surrounded by extensive, youthful pyroclastic-flow deposits.
This volcano was unknown to most volcanologists until recent years, but it is now known to have been the source of a major explosive eruption in 1641.
Parker volcano, also known locally as Falen, is a low, vegetated stratovolcano overlooking Sarangani Bay near the southern tip of Mindanao Island.
The steep-sided, 1824-m-high andesitic-dacitic stratovolcano is surrounded by extensive, youthful pyroclastic-flow deposits that suggest parallels to Pinatubo volcano.
The summit of Parker is truncated by a 2.9-km-wide caldera with steep-sided walls that rise 200-500 m above heart-shaped Maughan Lake.
This volcano was unknown to most volcanologists until recent years, but it is now known to have been the source of a major explosive eruption in 1641 that was previously attributed to Awu volcano on Sangihe Island, Indonesia and caused darkness over the is
indanao.
The 1641 eruption included the emplacement of voluminous pyroclastic flows and lahars and resulted in the formation of the summit caldera. This was the last of three major explosive eruptions from Parker during the last 3800 years.
