Grenada is an island country located between the Caribbean Sea and Atlantic Ocean, north of Trinidad and Tobago. It is located at 12°07′N61°40′W. There are no large inland bodies of water on the island, which consists entirely of the state of Grenada. The coastline is 121 km long. The island has 15 constituencies and speaks English and Grenadian Creole. It is volcanic in origin and its topography is mountainous.
Saint Kitts, officially Saint Christopher, is an island in the West Indies. The west side of the island borders the Caribbean Sea, and the eastern coast faces the Atlantic Ocean. Saint Kitts and the neighbouring island of Nevis constitute one country: the Federation of Saint Kitts and Nevis. Saint Kitts and Nevis are separated by a shallow 3-kilometre (2 mi) channel known as "The Narrows".
Mount Ruapehu is an active stratovolcano at the southern end of the Taupō Volcanic Zone and North Island volcanic plateau in New Zealand. It is 23 km (14 mi) northeast of Ohakune and 23 km (14 mi) southwest of the southern shore of Lake Taupō, within the Tongariro National Park. The North Island's major ski resorts and only glaciers are on its slopes.
The Lesser Antilles are a group of islands in the Caribbean Sea. Most of them are part of a long, partially volcanic island arc between the Greater Antilles to the north-west and the continent of South America. The islands of the Lesser Antilles form the eastern boundary of the Caribbean Sea where it meets the Atlantic Ocean. Together, the Lesser Antilles and the Greater Antilles make up the Antilles. The Lesser and Greater Antilles, together with the Lucayan Archipelago, are collectively known as the West Indies.
Mount Pelée or Mont Pelée is an active volcano at the northern end of Martinique, an island and French overseas department in the Lesser Antilles Volcanic Arc of the Caribbean. Its volcanic cone is composed of stratified layers of hardened ash and solidified lava. Its most recent eruption was in 1932.
La Soufrière or Soufrière Saint Vincent is an active volcano on the Caribbean island of Saint Vincent in Saint Vincent and the Grenadines. It is the highest peak in Saint Vincent, and has had eight recorded eruptions since 1718. The latest eruptive activity began on 27 December 2020 with the slow extrusion of a dome of lava, and culminated in a series of explosive events between 9 and 22 April 2021.
Kick 'em Jenny is an active submarine volcano or seamount on the Caribbean Sea floor, located 8 km (5 mi) north of the island of Grenada and about 8 km (5 mi) west of Ronde Island in the Grenadines. Kick-'em-Jenny rises 1,300 m (4,265 ft) 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.
The West Indies is a subregion of North America, surrounded by the North Atlantic Ocean and the Caribbean Sea, which comprises 13 independent island countries and 19 dependencies in three archipelagos: the Greater Antilles, the Lesser Antilles, and the Lucayan Archipelago.
Mount Tendürek is a shield volcano on the border of Ağrı and Van provinces in eastern Turkey, near the border with Iran. The volcano, which is mostly known for being near the supposed wreck site of Noah's Ark, is very large; its lava flows cover roughly 650 km2 (251 sq mi) across a swath of flat land. The mountain's two main features are the main summit crater Greater Tendürek, and a smaller crater known as Lesser Tendürek which lies to the east of the main crater. The slopes are very gentle and resemble a shield, after which the type is named. Mount Tendürek is known to have erupted viscous lava like that of volcanoes on the island of Hawaii.
Caille Island is a 155-acre private island situated 4 miles off the northern end of the Caribbean island of Grenada. It’s adjacent to Ronde Island and lies between Grenada and Carriacou. Caille’s name is believed to have derived from the French word “caillou” meaning “pebble” in English, which is indicative of the stones naturally adorning the landscape. Along with sandy beaches and bays along the coastline, an abundance of green vegetation, coconut palms, and a variety of fruit trees can be found.
The following is an alphabetical list of topics related to the nation of Grenada.
A lateral eruption or lateral blast is a volcanic eruption which is directed laterally from a volcano rather than upwards from the summit. Lateral eruptions are caused by the outward expansion of flanks due to rising magma. Breaking occurs at the flanks of volcanoes making it easier for magma to flow outward. As magma is pushed upward towards the volcano it diverges towards the flanks before it has a chance to erupt from the crater. When the expanding flank finally gives it releases a flow of magma. More explosive lateral eruptions are referred to as lateral blasts. Some of the most notable examples of a lateral eruption include Mount St. Helens, Mount Pelée, and Mount Etna.
A flank eruption is a volcanic eruption which occurs on the flanks of a volcano, instead of at its summit. Such eruptions occur when the conduit connecting the summit to the magma chamber below is blocked, forcing the magma to move laterally.
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. 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 10 kilometres (5.4 nmi) north of Grenada.
The Mount St. Catherine Forest Reserve is the second largest declared terrestrial protected area in Grenada after the Grand Etang and Annandale Forest Reserves. Covering 934 ha within a 31.7 km (19.7 mi) boundary perimeter, its headwaters drain across seven of the largest watersheds on the island and supply important catchment basins for water distribution to Grenadians and agrarian landscapes downstream. The forest reserve encompasses the principal peak of the Mount Saint Catherine massif—the highest point on the island 840 m (2,760 ft), as well as other lushly forested ridges and lesser peaks, the highest waterfall in the country, the majority of the island's known hot springs, including the hottest geothermal spring and its most accessible geothermal bathing pool.
The geology of Martinique originated from volcanic eruptions, but has different rocks than nearby Lesser Antilles volcanic island arc islands all of which formed in the last 40 million years in the Cenozoic. A high-alumina basalt ranges from olivine basalt to tridymite-rich dacite. Calc-alkaline volcanic rocks are rich in hornblende and orthpyroxene andesite, hornblende andesite and quartz-hornblende dacite are also common. Mount Pelee is one of the most active Caribbean volcanoes with 20 eruptions in the last 5000 years. It also heats groundwater, generating hydrothermal eruptions at sulfur springs in 1751 and 1851.
Richard E. A. Robertson is a Professor of Geology and past Director of the University of the West Indies Seismic Research Centre. He studied Geology and Volcanology at Mona Campus of the University of the West Indies in Jamaica and Leeds University, United Kingdom.
Jan Marie Lindsay is a New Zealand geologist and Professor of Volcanology at Waipapa Taumata Rau, the University of Auckland in Aotearoa New Zealand.
Erouscilla "Pat" Joseph is a volcanologist, and Director of the University of the West Indies Seismic Research Centre, which oversees seismic and volcanic monitoring of the English-speaking Eastern Caribbean. She led the volcanological management of the 2021 La Soufriere eruptions on Saint Vincent, for which the Seismic Research Centre received global accolades.
The University of the West Indies Seismic Research Centre (UWI-SRC) is a centre for volcanological, seismic and geophysical research in Trinidad, which has the responsibility for monitoring and studying earthquakes, volcanoes and tsunamis across the Eastern Caribbean. Part of the University of the West Indies, it is also responsible for providing formal advice, and information, around the volcanic, seismic and tsunami hazards and events across the region, to reduce risk and protect lives and livelihoods. In recent years, UWI-SRC has managed ongoing volcanic unrest at the Soufriere Hills Volcano through the running of the Montserrat Volcano Observatory, and the 2020–2021 eruptions of La Soufrière on St Vincent.
