Lake Maughan

Mount Mélébingóy, formerly known as Parker Volcano, is an active volcano on Mindanao island in the Philippines (6°06.8' N, 124°53.5' E). It is located in the province of South Cotabato, west of General Santos City and south of Koronadal City.

The volcano's English name is taken from an American, General Frank Parker, who spotted the mountain and claimed to have "discovered" it during a flight he piloted in 1934. Parker led an expedition up to the lake in the mountain's crater with other US colonial and Filipino government officials, including Vice-Governor-General Joseph Ralston Hayden and Provincial Governor Gutierrez, in the fall of 1934.J. R. Hayden to Captain C. Morera, September 4, 1934 AND Hayden to Gov. Gutierrez, January 15, 1935, Joseph Ralston Hayden Papers, Box 27, Folder 32, Bentley Historical Library, University of Michigan.

Physical features

The elevation is given as by some sources and as by others. The volcano has a base diameter of . It has a wide caldera with steep walls that rise 200-500m above the lake that is now called Lake Maughan. The lake, which is officially called Lake Hólón, was named after another American who was with Parker when he crashed.

Mélébingóy is considered one of the sacred places of the Tboli tribe. It hosts a rare species, '' Parantica dannatti reyesi'', a butterfly related to the monarch, which was discovered by the late Professor Josue de los Reyes of Notre Dame of Marbel University and published in the entomological journal of Senckerburg Research Institute in December 1994.

Government officials have also confirmed sightings of the Philippine tarsier, ''Tarsius syrichta,'' which can supposedly be found in the barangays surrounding Lake Hólón.

Eruptions

Mount Parker is believed to have erupted thrice over the past 3,800 years, the last one on January 4, 1641. The 1641 eruption caused the formation of the crater lake.

On September 6, 1995, local officials reported what they believed was volcanic activity at Lake Maughan. The alleged activity caused landslides and flooding along Ga-o River that drains Lake Maughan and joins Allah River in the north. Due to this phenomenon, the Philippine Institute of Volcanology and Seismology installed monitoring equipment that established that the so-called activity was man-made.

Less than a year after the 1995 activity, a temporary dam was formed at about 250 m from the outlet of Lake Maughan, alarming the residents within the area due to fear of flash floods. The deposited debris dammed the flowing Ga-o River and caused the lake level to rise by about 6 meters.
