List Of Earthquakes In Vanuatu
Earthquakes in Vanuatu are frequent and are sometimes accompanied by tsunami, though these events are not often destructive. The archipelago, which was formerly known as New Hebrides, lies atop a complex and active plate boundary in the southwestern Pacific Ocean. Overall, the population in this region resides in structures that are highly vulnerable to earthquake shaking, though some resistant structures exist. Most buildings in Vanuatu are constructed with lumber. Tectonic setting The primary tectonic feature of the island chain is the New Hebrides Trench, the convergent boundary of the Australian and Pacific Plates. Along the Wadati–Benioff zone, earthquake activity has been observed as shallow, intermediate, and deep-focus events at depths of up to . Volcanic activity is also present along this north-northwest trending and northeast- dipping oceanic trench. While much of the island arc experiences intermediate-depth earthquakes along a Wadati–Benioff zone that dips st ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
New Hebrides
New Hebrides, officially the New Hebrides Condominium (french: link=no, Condominium des Nouvelles-Hébrides, "Condominium of the New Hebrides") and named after the Hebrides Scottish archipelago, was the colonial name for the island group in the South Pacific Ocean that is now Vanuatu. Native people had inhabited the islands for three thousand years before the first Europeans arrived in 1606 from a Spanish expedition led by Portuguese navigator Pedro Fernandes de Queirós. The islands were colonised by both the British and French in the 18th century, shortly after Captain James Cook visited. The two countries eventually signed an agreement making the islands an Anglo-French condominium that divided New Hebrides into two separate communities: one Anglophone and one Francophone. That divide continued even after independence, with schools teaching in either one language or the other, and with different political parties. The condominium lasted from 1906 until 1980, when New He ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
United States Geological Survey
The United States Geological Survey (USGS), formerly simply known as the Geological Survey, is a scientific agency of the United States government. The scientists of the USGS study the landscape of the United States, its natural resources, and the natural hazards that threaten it. The organization's work spans the disciplines of biology, geography, geology, and hydrology. The USGS is a fact-finding research organization with no regulatory responsibility.

1999 Ambrym Earthquake
The 1999 Ambrym earthquake occurred on November 26 at with a moment magnitude of 7.4 and a maximum Mercalli intensity of VII (''Very strong''). The back arc thrust event occurred within the Vanuatu archipelago, just to the south of the volcanic island of Ambrym. Vanuatu, which was previously known as New Hebrides, is subject to volcanic and earthquake activity because it lies on an active and destructive plate boundary called the New Hebrides Subduction Zone. While the National Geophysical Data Center classified the total damage as moderate, a destructive local tsunami did result in some deaths, with at least five killed and up to 100 injured. This was one of very few events along the New Hebrides Subduction Zone that has been studied. Scientists from technical institutes in the region submitted papers to the scientific journals about the event, and while not all data on each of the aspects of the event are in agreement, what is certain is that the d'Entrecasteaux Ridge is pro ...

2002 Port Vila Earthquake
The 2002 Port Vila earthquake occurred in the early dawn of January 3, 2002, 04:22 a.m. local time (UTC+11) northwest of Port Vila, the capital of Vanuatu. It had a magnitude of 7.2 and a maximum intensity of X (''Extreme'') west of the island on the Modified Mercalli intensity scale. There are no exact estimates on the number of injured individuals, but the majority of accounts say there were "several" amounts of injured civilians. the event also caused a minor tsunami of about 0.4−0.8 m just 11 minutes after the quake. Tectonic setting The tremor was caused by the convergence of the Australian Plate and the New Hebrides microplate. Different rates of convergence are present in different regions, in the southern Tanna regions the relative movement is oriented at around N244 ±4 and has a uniform rate of 11.7±0.8 cm/yr. The rate in Efaté, near the epicenter, was at around 0.3±0.9 cm/yr, oriented N242 ±4. Both azimuths very well compare with slip vectors of the last maj ...

Efate
Efate (french: Éfaté) is an island in the Pacific Ocean which is part of the Shefa Province in Vanuatu. It is also known as Île Vate. Geography It is the most populous (approx. 66,000) island in Vanuatu. Efate's land area of makes it Vanuatu's third largest island. Its geological past was heavily volcanic, meaning that a lava shelf surrounds much of the island. Most inhabitants of Efate live in Port Vila, the national capital. Its highest mountain is Mount McDonald with a height of . History Captain James Cook named it Sandwich Island "in honour of my noble patron, the Earl of Sandwich" on his 1774 voyage on . During World War II, Efate served an important role as a United States military base. On March 13, 2015, Port Vila, the island's largest human settlement and the capital of Vanuatu, bore extensive damage from Cyclone Pam. Politics Efate became an independent commune in 1889 when residents declared the region as Franceville. However, by 1890 the commune was broke ...

2009 Vanuatu Earthquakes
The 2009 Vanuatu earthquakes were three earthquakes with magnitudes ranging from 7.4 to 7.8, constituting some of the largest earthquakes in Vanuatu's history. Tectonic Setting The Vanuatu earthquakes of October 7, 2009: M 7.7, Vanuatu, 22:03:14; M 7.8 Santa Cruz Islands, 22:18:51 UTC; and M 7.4, Vanuatu, 23:13:48; all occurred as a result of shallow reverse faulting on or near the plate boundary interface between the Indo-Australian Plate and Pacific Plates. In the region of these earthquakes, the Indo-Australian plate moves to the east-northeast with respect to the Pacific plate at a velocity of about 91 mm/yr. The Indo-Australian plate thrusts under the Pacific plate at the New Hebrides Trench and dips to the east-northeast. The locations, depths, and focal mechanism solutions for the October 7th events are all consistent with them resulting from reverse faulting associated with subduction along the Australia-Pacific plate boundary. The 7.8 earthquake of October 7, 2009 (22: ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Shefa Province
Shefa is one of the six provinces of Vanuatu, located in the center of the country and including the islands of Epi and Efate and the Shepherd Islands. The province's name is derived from the initial letters of SHepherd and EFAte. It has a population of 78,723 people and an area of 1,455 km2. Its capital is Port Vila, which is also the capital of the nation. History In the 1860s, Havanna Harbour, north Efate, was the centre of development in Shefa, with cotton plantations the focus. With dwindling prices for cotton, agricultural administrators turned to maize and coffee, before settling mainly with coconuts and cattle which are the main agricultural products today. The French and British continued to have conflicting interests in Vanuatu (then known as New Hebrides) and decided upon a Joint Naval Commission, or Condominium, in 1887, with the Joint Court opened in 1910, it is still used today. Shefa Province was a strategic location during World War II for the mainly Americ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Tafea Province
Tafea is the southernmost of the six provinces of Vanuatu. The name is an acronym for the five main islands that make up the province: Tanna, Aneityum, Futuna, Erromango and Aniwa. History Unlike the other provinces of Vanuatu, the territorial integrity of this administrative unit has been unchanged since the times of the Condominium, when it was called ''Southern District'', or ''Tanna'' after the main island. Only the capital moved from Lenakel to nearby Isangel, less than two kilometers more southeast. A secessionist movement began in the 1970s, and the Nation of Tanna was proclaimed on 24 March 1974. While the British were more open to allowing its holdings in Vanuatu independence, it was opposed by the French colonists and finally suppressed by the Anglo-French Condominium authorities on 29 June 1974. In 1980, there was another attempt to secede, declaring the Tafea Nation on 1 January 1980, its name coming from the initials of the five islands that were to be part o ...
