Mount Melibengoy

Mount Melibengoy is a earth science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Mount Melibengoy rather than just read about it. In short: Mount Melibengoy, formerly known as Parker Volcano, is an active volcano on Mindanao island in the Philippines. It is located in the province of South Cotabato, 30 km (19 mi) west of General Santos and 44 km (27 mi) south of Koronadal.

Key takeaways

Mount Melibengoy belongs to earth science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Mount Melibengoy to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Mount Melibengoy from memory before moving on to harder problems.

Reference excerpt

Mount Melibengoy, formerly known as Parker Volcano, is an active volcano on Mindanao island in the Philippines. It is located in the province of South Cotabato, 30 km (19 mi) west of General Santos and 44 km (27 mi) south of Koronadal. 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.

Physical features

The elevation is given as 1,784 metres (5,853 ft) by some sources and as 1,824 metres (5,984 ft) by others. The volcano has a base diameter of 40 kilometres (25 mi). It has a 2.9-kilometre (1.8 mi) wide caldera with steep walls that rise 200-500m above the lake that is now called Lake Maughan. The lake, which is commonly called Lake Holon, was named after another American who was with Parker when he crashed. Melibengoy is considered one of the sacred places of the T'boli 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 Holon.

Eruptions

Mount Melibengoy 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. It also led to the collapse of the Ming Dynasty in China in 1644 by exacerbating an already multi year drought in the region. 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 (820 ft) 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 m (20 ft).

Worked examples

Example 1 — a first encounter with Mount Melibengoy

Start with the simplest possible case. Write down what Mount Melibengoy claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In earth science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Mount Melibengoy before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Mount Melibengoy ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Mount Melibengoy

In research: Mount Melibengoy appears in earth science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Mount Melibengoy in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Mount Melibengoy is common in secondary-school and first-year university syllabi. It links to neighbouring topics 17th-century volcanic events, Active volcanoes of the Philippines, Landforms of South Cotabato, so understanding it makes those chapters shorter.
In everyday life: Look for Mount Melibengoy outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
