Pauahi Crater

Pauahi Crater 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 Pauahi Crater rather than just read about it. In short: Pauahi Crater is a volcanic crater measuring 2,000 ft (610 m) long, up to some 1,300 ft (400 m) across, and 300 ft (91 m) deep in Hawaii Volcanoes National Park at 19°22′6″N 155°13′21″W. It is about 3 mi (4.8 km) from the top of the Big Island of Hawaii's Chain of Craters Road, which follows a "chain" that also includes the Hiʻiaka, Puʻu Huluhulu, Kānenuiohamo, Makaopuhi and Nāpau craters.

Key takeaways

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

Reference excerpt

Pauahi Crater is a volcanic crater measuring 2,000 ft (610 m) long, up to some 1,300 ft (400 m) across, and 300 ft (91 m) deep in Hawaii Volcanoes National Park at 19°22′6″N 155°13′21″W. It is about 3 mi (4.8 km) from the top of the Big Island of Hawaii's Chain of Craters Road, which follows a "chain" that also includes the Hiʻiaka, Puʻu Huluhulu, Kānenuiohamo, Makaopuhi and Nāpau craters.

Eruptive history Three historic eruptions have occurred at or near Pauahi Crater. The first was in May 1973 when a fissure opened and erupted briefly on its floor. The second took place in November 1973 and lasted 31 days (November 10 — December 9), but most activity was concentrated during the event's initial 10 hours. The eruption created a set of echelon fissures extending over some 2 mi (3.2 km) from a point just west of the crater, across the crater floor, and on eastward almost to Puu Huluhulu. The third eruption occurred on November 16, 1979, and lasted only one day.

Worked examples

Example 1 — a first encounter with Pauahi Crater

Start with the simplest possible case. Write down what Pauahi Crater 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 Pauahi Crater 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 Pauahi Crater 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 Pauahi Crater

In research: Pauahi Crater 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 Pauahi Crater 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: Pauahi Crater is common in secondary-school and first-year university syllabi. It links to neighbouring topics 1973 in the United States, Hawaii geography stubs, Hawaiʻi Volcanoes National Park, so understanding it makes those chapters shorter.
In everyday life: Look for Pauahi Crater 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.
