Savo Island

Savo Island 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 Savo Island rather than just read about it. In short: Savo Island is an island in Solomon Islands in the South Pacific ocean. Administratively, Savo Island is a part of the Central Province of Solomon Islands.

Key takeaways

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

Reference excerpt

Savo Island is an island in Solomon Islands in the South Pacific ocean. Administratively, Savo Island is a part of the Central Province of Solomon Islands. It is about 35 kilometres (22 mi) from the national capital of Honiara. The principal village is Alialia, in the north of the island. The indigenous language of Savo is the Savosavo language, an East Papuan language. Savo Island also has a minority of Gela speakers. The waters surrounding the island were the site of five of the seven major naval battles during the Battle of Guadalcanal in the Pacific War of World War II. As a result of these battles, many shipwrecks are located southeast of the island; the bay is known as Ironbottom Sound. The wrecks near the coast are very popular with wreck divers.

Geography Savo is approximately circular, measuring approximately 6 kilometres (3.7 mi) by 7 kilometres (4.3 mi). It is located 15 kilometres (9.3 mi) northeast of Cape Esperance, the northern tip of Guadalcanal. The highest elevation is a 485 metres (1,591 ft) stratovolcano, which last erupted between 1835 and 1847. The eruption was so strong that it wiped out all life on the island. An older eruption occurred in 1568. According to the World Organization of Volcanic Observatories (WOVO), the volcano is active every 100 to 300 years. On the island are geysers, hot mud lakes and hot springs.

The "egg fields" Savo Island is known for the "egg fields" of the megapode, a bird which lays its eggs here and buries them in the warm sand to incubate. The eggs are excavated by local people and are considered a local food specialty. The eggs are slightly larger than a duck egg and are used for preparing omelettes and other dishes.

History

European discovery and exploration The first recorded sighting of Savo Island by European explorers was by the Spanish expedition of Álvaro de Mendaña in April 1568. More precisely the sighting was due to a local exploration voyage done by a small boat, in the accounts the brigantine, commanded by maestre de campo Pedro de Ortega Valencia and having Hernán Gallego as pilot. They charted the volcanic island as Sesarga. Considering the expedition leaders Mendaña and cosmographer Pedro Sarmiento de Gamboa were both from Galicia in Spain, it was probably so named after the island of the same name in this region. On 15 March 1893, Savo Island was declared part of the British Solomon Islands protectorate. The island was occupied by the Empire of Japan in the early stages of the Pacific War.

World War II Because of its proximity to Guadalcanal Island and the hotly contested nature of the battles for control of the Solomon Islands, Savo Island figured in many of the naval engagements of the Solomon Islands campaign. It is most well known as the location of several naval battles fought in the adjacent "Ironbottom Sound" during World War II, between the Allied naval forces and the Imperial Japanese Navy.

List of World War II naval battles fought in the vicinity of Savo Island:

Battle of Savo Island, 8-9 August 1942 Battle of Cape Esperance (originally known as the "Second Battle of Savo Island"), 11–12 October 1942 Naval Battle of Guadalcanal, 13–15 November 1942 Battle of Tassafaronga, 30 November 1942 Since 1978, the island has been part of the independent state of Solomon Islands.

Worked examples

Example 1 — a first encounter with Savo Island

Start with the simplest possible case. Write down what Savo Island 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 Savo Island 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 Savo Island 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 Savo Island

In research
Savo Island 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 Savo Island 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
Savo Island is common in secondary-school and first-year university syllabi. It links to neighbouring topics Islands of the Solomon Islands, Stratovolcanoes of the Solomon Islands, Subduction volcanoes, so understanding it makes those chapters shorter.
In everyday life
Look for Savo Island 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.
