Bismarck Archipelago
The Bismarck Archipelago (, ) is a group of islands off the northeastern coast of New Guinea in the western Pacific Ocean and is part of the Islands Region of Papua New Guinea. Its area is about . History The first inhabitants of the archipelago arrived around 30,000–40,000 years ago. They may have traveled from New Guinea, by boat across the Bismarck Sea or via a temporary land bridge, created by an uplift in the Earth's crust. Later arrivals included the Lapita people, the direct ancestors of the Austronesian peoples of Polynesia, eastern Micronesia, and Island Melanesia. The first European to visit these islands was Dutch explorer Willem Schouten in 1616. The islands remained unsettled by western Europeans until they were annexed as part of the German protectorate of German New Guinea in 1884. The area was named in honour of the Chancellor Otto von Bismarck. On 13 March 1888, a volcano erupted on Ritter Island causing a megatsunami. Almost the entire volcano fell int ...

New Britain
New Britain () is the largest island in the Bismarck Archipelago, part of the Islands Region of Papua New Guinea. It is separated from New Guinea by a northwest corner of the Solomon Sea (or with an island hop of Umboi Island, Umboi the Dampier Strait (Papua New Guinea), Dampier and Vitiaz Straits) and from New Ireland (island), New Ireland by St. George's Channel (Papua New Guinea), St. George's Channel. The main towns of New Britain are Rabaul/Kokopo and Kimbe. The island is roughly the size of Taiwan. When the island was part of German New Guinea, its name was Neupommern ("New Pomerania"). In common with most of the Bismarcks it was largely formed by volcanic processes, and has active volcanoes including Ulawun (highest volcano nationally), Langila, the Garbuna Group, the Sulu Range, and the volcanoes Tavurvur and Vulcan (volcano), Vulcan of the Rabaul caldera. A major eruption of Tavurvur in 1994 destroyed the East New Britain provincial capital of Rabaul. Most of the to ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protectorate
A protectorate, in the context of international relations, is a State (polity), state that is under protection by another state for defence against aggression and other violations of law. It is a dependent territory that enjoys autonomy over most of its internal affairs, while still recognizing the suzerainty of a more powerful sovereign state without being a possession. In exchange, the protectorate usually accepts specified obligations depending on the terms of their arrangement. Usually protectorates are established de jure by a treaty. Under certain conditions—as with History of Egypt under the British#Veiled Protectorate (1882–1913), Egypt under British rule (1882–1914)—a state can also be labelled as a de facto protectorate or a veiled protectorate. A protectorate is different from a colony as it has local rulers, is not directly possessed, and rarely experiences colonization by the suzerain state. A state that is under the protection of another state while retai ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Empire Of Japan
The Empire of Japan, also known as the Japanese Empire or Imperial Japan, was the Japanese nation state that existed from the Meiji Restoration on January 3, 1868, until the Constitution of Japan took effect on May 3, 1947. From Japan–Korea Treaty of 1910, 1910 to Japanese Instrument of Surrender, 1945, it included the Japanese archipelago, the Kuril Islands, Kurils, Karafuto Prefecture, Karafuto, Korea under Japanese rule, Korea, and Taiwan under Japanese rule, Taiwan. The South Seas Mandate and Foreign concessions in China#List of concessions, concessions such as the Kwantung Leased Territory were ''de jure'' not internal parts of the empire but dependent territories. In the closing stages of World War II, with Japan defeated alongside the rest of the Axis powers, the Japanese Instrument of Surrender, formalized surrender was issued on September 2, 1945, in compliance with the Potsdam Declaration of the Allies of World War II, Allies, and the empire's territory subsequent ...

League Of Nations Mandate
A League of Nations mandate represented a legal status under international law for specific territories following World War I, involving the transfer of control from one nation to another. These mandates served as legal documents establishing the internationally agreed terms for administering the territory on behalf of the League of Nations. Combining elements of both a treaty and a constitution, these mandates contained minority rights clauses that provided for the rights of petition and adjudication by the Permanent Court of International Justice. The mandate system was established under Article 22 of the Covenant of the League of Nations, entered into force on 28 June 1919. With the dissolution of the League of Nations after World War II, it was stipulated at the Yalta Conference that the remaining mandates should be placed under the trusteeship of the United Nations, subject to future discussions and formal agreements. Most of the remaining mandates of the League of Na ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Australian Naval And Military Expeditionary Force
The Australian Naval and Military Expeditionary Force (AN&MEF) was a small volunteer force of approximately 2,000 men, raised in Australia shortly after the outbreak of World War I to seize and destroy German wireless stations in German New Guinea in the south-west Pacific. The German wireless installations were ordered to be destroyed because they were used by ''Vizeadmiral'' (Vice Admiral) Maximilian von Spee's East Asia Squadron of the Imperial German Navy, which threatened merchant shipping in the region. Following the capture of German possessions in the region, the AN&MEF provided occupation forces for the duration of the war. New Zealand provided a similar force for the occupation of German Samoa. History ] Formation The Australian Naval and Military Expeditionary Force (AN&MEF) began forming following a request by the British government on 6 August 1914.Grey 2008, p. 86. The objectives of the force were the German stations at Yap in the Caroline Islands, Nauru and at ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
World War I
World War I or the First World War (28 July 1914 – 11 November 1918), also known as the Great War, was a World war, global conflict between two coalitions: the Allies of World War I, Allies (or Entente) and the Central Powers. Fighting took place mainly in European theatre of World War I, Europe and the Middle Eastern theatre of World War I, Middle East, as well as in parts of African theatre of World War I, Africa and the Asian and Pacific theatre of World War I, Asia-Pacific, and in Europe was characterised by trench warfare; the widespread use of Artillery of World War I, artillery, machine guns, and Chemical weapons in World War I, chemical weapons (gas); and the introductions of Tanks in World War I, tanks and Aviation in World War I, aircraft. World War I was one of the List of wars by death toll, deadliest conflicts in history, resulting in an estimated World War I casualties, 10 million military dead and more than 20 million wounded, plus some 10 million civilian de ...

Geophysical Journal International
''Geophysical Journal International'' (GJI) is a monthly Peer review, peer-reviewed scientific journal in the field of geophysics. It is published by Oxford University Press on behalf of two learned societies: the Royal Astronomical Society (RAS) and the Deutsche Geophysikalische Gesellschaft (German Geophysical Society, DGG), who select and peer-review the contents. GJI was formed in 1988 by the merger of three earlier geophysics journals, the oldest of which was established in 1922. The editor-in-chief is Joerg Renner (Ruhr University Bochum). The journal publishes original research papers, research notes, letters, and book reviews. Its topical scope includes research on all aspects of theoretical, computational, applied and observational geophysics. History GJI was formed by a complex series of mergers between previous geophysical journals. Its origins can be traced to 1919, when the RAS absorbed the Geophysical Committee (which had previously been part of the British Assoc ...

Megatsunami
A megatsunami is an incredibly large wave created by a substantial and sudden displacement of material into a body of water. Megatsunamis have different features from ordinary tsunamis. Ordinary tsunamis are caused by underwater tectonic activity (movement of the earth's plates) and therefore occur along plate boundaries and as a result of earthquakes and the subsequent rise or fall in the sea floor that displaces a volume of water. Ordinary tsunamis exhibit shallow waves in the deep waters of the open ocean that increase dramatically in height upon approaching land to a maximum run-up height of around in the cases of the most powerful earthquakes. By contrast, megatsunamis occur when a large amount of material suddenly falls into water or anywhere near water (such as via a landslide, meteor impact, or volcanic eruption). They can have extremely large initial wave heights in the hundreds of metres, far beyond the height of any ordinary tsunami. These giant wave heights occur ...

Ritter Island
Ritter Island is a small crescent-shaped volcanic island north-east of New Guinea, situated between Umboi Island and Sakar Island. There are several recorded eruptions of this basaltic-andesitic stratovolcano prior to a spectacular lateral collapse which took place in 1888. Before that event, it was a circular conical island about high. 1888 eruption At about 5:30 am local time on 13 March 1888 a large portion of the island, containing perhaps of material slid into the sea during a relatively minor, possibly VEI 2, phreatic eruption. Eyewitnesses at Finschhafen, to the south, heard explosions and observed an almost imperceptible ash fall. Tsunami A tsunami ( ; from , ) is a series of waves in a water body caused by the displacement of a large volume of water, generally in an ocean or a large lake.

Volcano
A volcano is commonly defined as a vent or fissure in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and because most of Earth's plate boundaries are underwater, most volcanoes are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes resulting from divergent tectonic activity are usually non-explosive whereas those resulting from convergent tectonic activity cause violent eruptions."Mid-ocean ridge tectonics, volcanism and geomorphology." Geology 26, no. 455 (2001): 458. https://macdonald.faculty.geol.ucsb.edu/papers/Macdonald%20Mid-Ocean%20Ridge%20Tectonics.pdf Volcanoes can also form where there is str ...

1888 Ritter Island Eruption And Tsunami
On 13 March 1888, a section of Ritter Island, a small volcanic island off the coast of New Guinea, collapsed into the sea in a sector collapse. The collapse triggered tsunami waves that struck nearby and distant islands such as New Guinea, Umboi, Sakar and New Britain. It caused heavy damage and deaths in coastal settlements. While no confirmed death toll exists, it is estimated that between 1,500 and 3,000 people died. Background Ritter Island in the Bismarck Archipelago is an active stratovolcano located off the northeast coast of Papua New Guinea. It is one of the many active volcanoes in Papua New Guinea as a result of subduction of the Solomon Sea plate beneath the Bismarck Plate along the New Britain Trench. Before the eruption of 1888, the island was a steep-sided and almost-circular volcanic cone which was recognisable to sailors passing through the Dampier Strait (Papua New Guinea), Dampier Strait. It had an estimated height of . Based on sketches from the 1830s, the si ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
