Mount Saint Catherine is an extensively weathered stratovolcano mountain and tallest peak on the Caribbean island of Grenada. Its summit marks the dividing line between the parishes of St. Mark and St. Andrew and is one of the highlights of the Mount St. Catherine Forest Reserve.
The Mt. St. Catherine massif is the youngest of the five volcanoes on the island. [1] The volcano has a ~1.5-km horseshoe-shaped crater open to the east, where a complex of volcanic lava domes occur across its flanks and is monitored by the Seismic Research Center of the University of the West Indies. The volcano is considered dormant because it has likely not erupted since the last Ice Age. [2] It is considered to be the only live volcano among the five volcanic centers in Grenada on account of its relatively well preserved morphology and the presence of hot springs and fumaroles on its flanks. [3] Although violent eruptions occurred in the geological past (i.e. Pleistocene—2,588,000 to 11,700 years ago), revealed by voluminous pyroclastic-flow deposits extending northwest of the summit, this type of volcanic activity is now considered unlikely to occur in the near future. [4]
The mountain summit is accessible by three steep rugged routes crossing the forest reserve, from Mt. Horne in the southeast, Mt. Kublal in the northeast, and Tufton Hall from the northwest. Tours are available, as well as guided trips to Tufton Hall Waterfall, the highest waterfalls on the island, off the southeastern flank of the mountain.
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, forming part of the Caribbean islands or West Indies. They are distinguished from the larger islands of the Greater Antilles to the west. They form an arc which begins east of Puerto Rico at the archipelago of the Virgin Islands, swings southeast through the Leeward and Windward Islands towards South America, and turns westward through the Leeward Antilles along the Venezuelan coast.
Mount Pelée or Mont Pelée, meaning "bald mountain" or "peeled mountain" in French, 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.
Shishaldin Volcano, or Mount Shishaldin, is a moderately active volcano on Unimak Island in the Aleutian Islands chain of Alaska in the United States. It is the highest mountain peak of the Aleutian Islands and rises about 8,000 m (26,000 ft) from the bottom of the Aleutian Trench 140 mi (230 km) south of the volcano. The volcano's topographic contour lines are nearly perfect circles above 6,500 ft (2,000 m). The lower north and south slopes are somewhat steeper than the lower eastern and western slopes. Only on the volcano's west flank between about 3,500 to 6,500 ft are small areas of rough topography which are remnants of an older collapsed volcano upon which Shishaldin is built. The volcano is the westernmost of three large stratovolcanoes along an east–west line in the eastern half of Unimak Island.
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 on 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.
Guadeloupe is an archipelago of more than 12 islands, as well as islets and rocks situated where the northeastern Caribbean Sea meets the western Atlantic Ocean. It is located in the Leeward Islands in the northern part of the Lesser Antilles, a partly volcanic island arc. To the north lie Antigua and Barbuda and the British Overseas Territory of Montserrat, with Dominica lying to the south.
Mount Scenery is a dormant volcano in the Caribbean Netherlands. Its lava dome forms the summit of the Saba island stratovolcano. At an elevation of 887 m (2,910 ft), 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 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.
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.
