Peuët Sagoë

Peuët Sagoë 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 Peuët Sagoë rather than just read about it. In short: Peuet Sague is a volcanic complex in the northwestern part of Sumatra, Indonesia. The name peuet sagoe in Acehnese means four square.

Key takeaways

Peuët Sagoë 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 Peuët Sagoë to a quantity you can measure, compute or draw — that is where exam questions come from.
Reproduce the core statement of Peuët Sagoë from memory before moving on to harder problems.

Reference excerpt

Peuet Sague is a volcanic complex in the northwestern part of Sumatra, Indonesia. The name peuet sagoe in Acehnese means four square. The location of the volcanic complex is isolated that needs several journeys on foot from the nearest village to reach the mountain. There are four summits in the complex that all of them are located in Pidie Regency, Aceh Province. One of the lava dome is called Mount Tutung and it has 70 metres (230 feet) diameter and 80 meters (262.5 feet) deep of an active crater.

Eruptive history The first recorded eruption took place between 1918 and 1921. Due to its remoteness, the volcanic complex is infrequently visited. Little is known about its eruption history prior the 20th century. In the morning of 26 April 1998, an ash eruption was spotted by a pilot of the Garuda Indonesia airline. The pilot saw the ash around 3 km (9,840 feet) altitude when he flew over 7 km (23,000 feet) altitude. The local Indonesia Air Force chief confirmed the eruption from a fighter pilot who also spotted fire and thick smoke from the nearby forest. This was actually the second eruption from the first one on 19 April 1998, but the first eruption was obscured by a thick smoke from forest fires. Officials from the Ministry of Mines and Energy reported a phreatic eruption. The active crater was near Mount Tutung, 2 km (1.2 mi) west of the Peuet Sague's peak. Nobody was injured from this eruption because the nearest village is 8 km (5.0 mi) west of the mountain. From 9 March 1999 until 24 May 1999, volcanic activity in the Peuet Sague complex increased. Local people heard explosion noises about 20 times per day. Tectonic events increased and an eruption emitted white-gray ash up until 200 metres (656 feet) height. A white plume was observed between 10 and 20 metres (30–65 feet) height. All activities were then diminished. The 1999 activity was later discovered to be continued until late of December 2000, although at a decreased level. The activity monitoring at that time was stopped due to a malfunctioning seismograph. Plumes continued to rise in June up to heights of 20 metres. Rumbling was heard on 18 occasions, and plumes continued to rise through 14 June 1999. A renewed activity began on 25 December 2000 with three explosions. Ash was spread over a relatively large area. Reports of ashfall occurred on Geumpang, Lutung, Mane and Bangke villages, up to 20 km (12 mi) away. A glowing lava flows at night was also reported. The 2000 eruption was estimated at scale 2 on Volcanic Explosivity Index.

Worked examples

Example 1 — a first encounter with Peuët Sagoë

Start with the simplest possible case. Write down what Peuët Sagoë 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 Peuët Sagoë 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 Peuët Sagoë 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 Peuët Sagoë

In research: Peuët Sagoë 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 Peuët Sagoë 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: Peuët Sagoë is common in secondary-school and first-year university syllabi. It links to neighbouring topics Complex volcanoes, Landforms of Aceh, Mountains of Sumatra, so understanding it makes those chapters shorter.
In everyday life: Look for Peuët Sagoë 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.
