Lesser Antilles Volcanic Arc
The Lesser Antilles Volcanic Arc is a volcanic arc that forms the eastern boundary of the Caribbean Plate. It is part of a subduction zone, also known as the Lesser Antilles subduction zone, where the oceanic crust of the North American Plate is being subducted under the Caribbean Plate.The University of the West Indies Seismic Research CentreCaribbean Volcanoes Accessed: November 18, 2022. This subduction process formed a number of volcanic islands, from the Virgin Islands in the north to the islands off the coast of Venezuela in the south. The Lesser Antilles Volcanic Arc includes 21 'active' volcanoes, notably Soufriere Hills on Montserrat; Mount Pelée on Martinique; La Grande Soufrière on Guadeloupe; Soufrière Saint Vincent on Saint Vincent; Mount Scenery on Saba; and the submarine volcano Kick 'em Jenny which lies about north of Grenada.

Bathymetry Of The Northeast Corner Of The Caribbean Plate Showing The Major Faults And Plate Boundaries
Bathymetry (; ) is the study of underwater depth of ocean floors (''seabed topography''), lake floors, or river floors. In other words, bathymetry is the underwater equivalent to hypsometry or topography. The first recorded evidence of water depth measurements are from Ancient Egypt over 3000 years ago. Bathymetric (or hydrographic) charts are typically produced to support safety of surface or sub-surface navigation, and usually show seafloor relief or terrain as contour lines (called depth contours or isobaths) and selected depths ('' soundings''), and typically also provide surface navigational information. Bathymetric maps (a more general term where navigational safety is not a concern) may also use a Digital Terrain Model and artificial illumination techniques to illustrate the depths being portrayed. The global bathymetry is sometimes combined with topography data to yield a global relief model. Paleobathymetry is the study of past underwater depths. Seabed topography ...

La Grande Soufrière
La Grande Soufrière ( en, "big sulfur outlet"), is an active stratovolcano on the French island of Basse-Terre, in Guadeloupe. It is the highest mountain peak in the Lesser Antilles, rising 1,467 m high. The last magmatic eruption was in 1580±50 during which the current lava dome was emplaced. More recent eruptions have been phreatic in type. On February 8, 1843, an eruption of La Grande Soufrière caused by an earthquake killed over 5,000 people. Significant seismic activity in 1976 led to a mass evacuation of the island's 72,000 residents. There was a bitter, and well-publicized, controversy between scientists Claude Allègre and Haroun Tazieff on whether evacuation should occur. Allègre held that inhabitants should be evacuated, just in case, while Tazieff held that the ''Soufrière'' was harmless. The prefect decided to evacuate, erring on the side of covering his back. The volcano erupted on August 30, 1976, but much less severely than predicted by the Allègre side ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Grenada
Grenada ( ; Grenadian Creole French: ) is an island country in the West Indies in the Caribbean Sea at the southern end of the Grenadines island chain. Grenada consists of the island of Grenada itself, two smaller islands, Carriacou and Petite Martinique, and several small islands which lie to the north of the main island and are a part of the Grenadines. It is located northwest of Trinidad and Tobago, northeast of Venezuela and southwest of Saint Vincent and the Grenadines. Its size is , and it had an estimated population of 112,523 in July 2020. Its capital is St. George's. Grenada is also known as the "Island of Spice" due to its production of nutmeg and mace crops. Before the arrival of Europeans in the Americas, Grenada was inhabited by the indigenous peoples from South America. Christopher Columbus sighted Grenada in 1498 during his third voyage to the Americas. Following several unsuccessful attempts by Europeans to colonise the island due to resistance from res ...

Kick 'em Jenny
Kick 'em Jenny (also: Kick-'em-Jenny or Mt. Kick-'Em-Jenny) is an active submarine volcano or seamount on the Caribbean Sea floor, located north of the island of Grenada and about west of Ronde Island in the Grenadines. Kick-'em-Jenny rises above the sea floor on the steep inner western slope of the Lesser Antilles ridge. The South American tectonic plate is subducting the Caribbean tectonic plate to the east of this ridge and under the Lesser Antilles island arc. Etymology The volcano was unknown before 1939, although "Kick 'em Jenny" appeared on earlier maps as either the name of a small island now called Diamond Rock (or Île Diamante), or the name of the strait between Grenada and Ronde Island (or Île de Ronde). The name itself may be a reference to the waters sometimes being extremely rough. Activity The first record of the volcano was in 1939, although it must have erupted many times before that date. On 23–24 July 1939 an eruption broke the sea surface, sending ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Submarine Volcano
Submarine volcanoes are underwater vents or fissures in the Earth's surface from which magma can erupt. Many submarine volcanoes are located near areas of tectonic plate formation, known as mid-ocean ridges. The volcanoes at mid-ocean ridges alone are estimated to account for 75% of the magma output on Earth.Martin R. Speight, Peter A. Henderson, "Marine Ecology: Concepts and Applications", John Wiley & Sons, 2013. . Although most submarine volcanoes are located in the depths of seas and oceans, some also exist in shallow water, and these can discharge material into the atmosphere during an eruption. The total number of submarine volcanoes is estimated to be over 1 million (most are now extinct) of which some 75,000 rise more than 1 km above the seabed. Only 119 submarine volcanoes in Earth's oceans and seas are known to have erupted during the last 11,700 years. Hydrothermal vents, sites of abundant biological activity, are commonly found near submarine volcanoes. Effe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Saba (island)
Saba (; , ) is a Caribbean island which is the smallest special municipality (officially “public body”) of the Netherlands. It consists largely of the active volcano Mount Scenery, which at is the highest point of the entire Kingdom of the Netherlands. The island lies in the northern Leeward Islands portion of the West Indies, southeast of the Virgin Islands. Together with Bonaire and Sint Eustatius it forms the BES islands.

Mount Scenery
Mount Scenery is an active volcano in the Caribbean Netherlands. Its lava dome forms the summit of the Saba island stratovolcano. At an elevation of , it is the highest point in both the Kingdom of the Netherlands, and, since the dissolution of the Netherlands Antilles on 10 October 2010, the highest point in the Netherlands proper. The Saba volcano is potentially dangerous; the latest eruption was in or around the year 1640 and included explosions and pyroclastic flows. On 2 September 2019, Mt. Scenery Nature Park was elevated to the status of national park. It has a hiking trail to its summit, which is one of Saba's biggest tourist attractions. Along the way up the mountain can be found all of the climate zones on Saba, including a cloud forest at the summit.

Saint Vincent (island)
Saint Vincent is a volcanic island in the Caribbean. It is the largest island of the country Saint Vincent and the Grenadines and is located in the Caribbean Sea, between Saint Lucia and Grenada. It is composed of partially submerged volcanic mountains. Its largest volcano and the country's highest peak, Soufrière (volcano), La Soufrière, is active, with the latest episode of volcanic activity having begun in December 2020 and intensifying in April 2021. There were major territory wars between the indigenous population of the Black Caribs, also called the Garifuna, and Great Britain in the 18th century, before the island was ceded to the British in 1763 and again in 1783. Saint Vincent and the Grenadines gained independence from the United Kingdom on 27 October 1979 and became part of the British Commonwealth of Nations thereafter. Approximately 130,000 people currently live on the island, and the population saw significant migration to the UK in the early 1900s and between t ...

Volcanic Arc
A volcanic arc (also known as a magmatic arc) is a belt of volcanoes formed above a subducting oceanic tectonic plate, with the belt arranged in an arc shape as seen from above. Volcanic arcs typically parallel an oceanic trench, with the arc located further from the subducting plate than the trench. The oceanic plate is saturated with water, mostly in the form of hydrous minerals such as micas, amphiboles, and serpentine minerals. As the oceanic plate is subducted, it is subjected to increasing pressure and temperature with increasing depth. The heat and pressure break down the hydrous minerals in the plate, releasing water into the overlying mantle. Volatiles such as water drastically lower the melting point of the mantle, causing some of the mantle to melt and form magma at depth under the overriding plate. The magma ascends to form an arc of volcanoes parallel to the subduction zone. Volcanic arcs are distinct from volcanic chains formed over hotspots in the middle of a te ...
