San Vicente is a department of El Salvador in the center of the country. The capital is San Vicente. On October 4, 1834, San Vicente City of Austria and Lorenzana was made the capital of State of El Salvador during the Federal Republic of Central America. In 1840, it was no longer the capital of the State of El Salvador, but it continues to be the capital of the department. The department was created on June 12, 1824. The San Vicente department is 1,184 km2 (457 sq mi) and has a population in excess of 174,500. The forest Bosque La Joya is found in San Vincente.
The Poás Volcano, is an active 2,697-metre (8,848 ft) stratovolcano in central Costa Rica and is located within Poas Volcano National Park. It has erupted 40 times since 1828, with a strong eruption on April 2017—causing the evacuation of visitors and residents. The volcano and surrounding park were closed for nearly 17 months, with a 2.5 kilometer safety perimeter established around the erupting crater. On September 1, 2018, the park was reopened to the public only with limited access to the crater observation area. They have started to require a reservation on the National Park Website before visitation. Adjacent trails to Lake Botos, and the museum at the visitor center remained closed. The volcano erupted briefly twice in September 2019.
The Irazú Volcano is an active volcano in Costa Rica, situated in the Cordillera Central close to the city of Cartago.
Mount Griggs, formerly known as Knife Peak Volcano, is a stratovolcano, which lies 10 km behind the volcanic arc defined by other Katmai group volcanoes. Although no historic eruptions have been reported from Mount Griggs, vigorously active fumaroles persist in a summit crater and along the upper southwest flank. The fumaroles on the southwest flank are the hottest, and some of the flank fumaroles can roar so loudly that they can be heard from the valley floor. The slopes of Mount Griggs are heavily mantled by fallout from the 1912 eruption of Novarupta volcano. The summit consists of three concentric craters, the lowest and largest of which contains a recent summit cone topped by two craters. The volume of the volcanic edifice is estimated at 25 cubic kilometers (6.0 cu mi). Isotopic analysis indicates that the source of Griggs' magma is distinct from the other Katmai volcanoes.
Mount Martin is a stratovolcano, located on the Alaska Peninsula, United States, in Katmai National Park and Preserve. It is one of the volcanoes in the vicinity of the Valley of Ten Thousand Smokes. Mount Martin's cone stands only about 500 metres (1,600 ft) higher than the surrounding ridge. Although an eruption in 1953 is now considered questionable and no other confirmed eruptive activity has taken place at Mount Martin, there is intense fumarolic activity within its summit crater. The summit crater is also breached to the southeast. The 300 m (984 ft)-wide summit crater is often ice-free due to the geothermal heat and contains an intermittent acidic crater lake. The fumaroles in the summit crater produce extensive sulfur deposits.
Iliamna Volcano, or Mount Iliamna, is a glacier-covered stratovolcano in the largely volcanic Aleutian Range in southwest Alaska. Located in the Chigmit Mountain subrange in Lake Clark National Park and Preserve, the 10,016-foot (3,053 m) volcano lies approximately 134 miles (215 km) southwest of Anchorage on the west side of lower Cook Inlet. It is the 25th most prominent peak in the United States.
Turrialba Volcano is an active volcano in central Costa Rica that has been explosively eruptive in recent years including 2016 and in January, March and April 2017. Visitors used to be able to hike down into the main crater, but increased volcanic activity in 2014–17, resulting in large clouds of volcanic ash, led to the closure of the surrounding Turrialba Volcano National Park. However, with the eruptions subsiding, the park and access to the volcano reopened on December 4, 2020.
Izalco is an active stratovolcano on the side of the Santa Ana Volcano, which is located in western El Salvador. It is situated on the southern flank of the Santa Ana volcano. Izalco erupted almost continuously from 1770 to 1958 earning it the nickname of "Lighthouse of the Pacific", and experienced a flank eruption in 1966. During an eruption in 1926, the village of Matazano was buried and 56 people were killed. The volcano erupted on highly arable land which was used for the production of coffee, cacao, and sugar cane.
San Miguel is a stratovolcano in central-eastern El Salvador, approximately 15 kilometres (9.3 mi) southwest of the city of San Miguel. On January 16, 2002, a minor eruption of steam, gas, and ash occurred from the summit crater, lasting 3 hours but causing no real damage to life or property. Carbon dioxide emissions had been monitored since November 2001, and their steady increase continued to build up until the eruption.
Azufral is a stratovolcano located in the department of Nariño in southern Colombia, 12 km (7 mi) west of the town of Túquerres. It is the only volcano of the Western Ranges of the Colombian Andes. Its name derives from the Spanish word for sulfur, azufre. The volcano is considered semi-dormant but there are numerous fumaroles in the summit crater. The summit of the volcano has an altitude of 4,070 metres (13,350 ft), and the north-western side of the crater contains a crescent-shaped lake named Laguna Verde at 3,970 m (13,025 ft). The lake is 1,100 m (0.68 mi) long and 600 metres (2,000 ft) wide. and its bright green color is a result of the sulfur and iron-based deposits in the crater. There are also two other much smaller lakes in the crater, Laguna Negra and Laguna Cristal.
Mount Myōkō is an active stratovolcano in Honshu, Japan. It is situated at the southwest of Myōkō city, Niigata Prefecture, and a part of Jōshin'etsu-kōgen National Park. Mount Myōkō is listed as one of 100 Famous Japanese Mountains, and together with Mount Yahiko, it is well known as the "famous mountain" of Niigata Prefecture.
San Pedro is a Holocene composite volcano in northern Chile and at 6,155 metres (20,194 ft) in elevation one of the highest active volcanoes in the world. Part of the Chilean Andes' volcanic segment, it is part of the Central Volcanic Zone of the Andes, one of the four tracts of the Andean Volcanic Belt. This region of volcanism includes the world's two highest volcanoes Ojos del Salado and Llullaillaco. San Pedro, like other Andean volcanoes, was formed by the subduction of the Nazca Plate beneath the South America Plate. It has a neighbouring volcano, San Pablo, and is itself formed by two separate edifices usually known as the Old Cone and the Young Cone. These edifices are formed by rocks ranging from basaltic andesite over andesite to dacite and are emplaced on a basement formed by Miocene volcanic rocks.
The volcano Tacaná is the second highest peak in Central America at 4,060 metres (13,320 ft), located in the Sierra Madre de Chiapas of western Guatemala and southern Mexico. It is also known in Mexico as Volcán Tacina.
Volcán Putana, sometimes referred to as Jorqencal or Machuca, is a stratovolcano located In the Central Volcanic Zone (CVZ) of the Andes on the border between Bolivia and Chile and close to the Sairecabur volcanic complex. Its summit is 5,884 metres (19,304 ft) above sea level and contains a summit crater with two smaller craters nested within it. Beneath the summit, the volcano features a number of lava domes and lava flows, some of which originated in flank vents.
Mount Binuluan is a remote volcano in the Kalinga province of the Cordillera Administrative Region of the Philippines. The 2,329-metre-high (7,641 ft) mountain is part of the Cordillera Central mountain range on Luzon island, the largest island in the country. Binuluan exhibits active volcanism through numerous fumarole fields, solfataras and hot springs on its slope. There were reports of possible eruptions in 1952 and 1986, but they are unverified.
Euchlorine (KNaCu3(SO4)3O) is a rare emerald-green sulfate mineral found naturally occurring as a sublimate in fumaroles around volcanic eruptions. It was first discovered in fumaroles of the 1868 eruption at Mount Vesuvius in Campania, Italy by Arcangelo Scacchi. The name 'euchlorine' comes from the Greek word εΰχλωρος meaning "pale green" in reference to the mineral's color, other reported spellings include euclorina, euchlorin, and euchlorite.
The 1917 San Salvador earthquake occurred on June 7 at 18:55 local time near the Salvadoran capital. The hypocenter of the Mw 6.7 was at a shallow depth of 15 km (9.3 mi), and occurred along a shallow crustal fault near San Salvador. The earthquake caused significant destruction of the city and left approximately 1,050 dead. It was followed by an eruption on San Salvador that killed another 1,100. Only behind the earthquake of 1986, it is the second deadliest in El Salvador's history.
