Arenal Volcano is an active andesitic stratovolcano in north-western Costa Rica around 90 km (56 mi) northwest of San José, in the province of Alajuela, canton of San Carlos, and district of La Fortuna. The Arenal volcano measures at least 1,633 metres (5,358 ft) high. It is conically shaped with a crater 140 metres (460 ft) in diameter. Geologically, Arenal is considered a young volcano and it is estimated to be less than 7,500 years old. It is also known as "Pan de Azúcar", "Canaste", "Volcan Costa Rica", "Volcan Río Frío" or "Guatusos Peak".
A volcanic field or crater row is an area of Earth's crust that is prone to localized volcanic activity. The type and number of volcanoes required to be called a "field" is not well-defined. Volcanic fields usually consist of clusters of up to 100 volcanoes such as cinder cones. Lava flows may also occur. They may occur as a monogenetic volcanic field or a polygenetic volcanic field.
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, including April 2017 when visitors and residents were evacuated. 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 reopened with limited access only to the crater observation area and required a reservation to be made on the National Park Website. Adjacent trails to Lake Botos as well as the museum at the visitor center remained closed. The volcano erupted briefly twice in September 2019.
Masaya is a caldera located in Masaya, Nicaragua, 20 km (12 mi) south of the capital Managua. It is Nicaragua's first and largest national park, and one of 78 protected areas of Nicaragua. The complex volcano is composed of a nested set of calderas and craters, the largest of which is Las Sierras shield volcano and caldera. Within this caldera lies a sub-vent, which is Masaya Volcano sensu stricto. The vent is a shield type composing of basaltic lavas and tephras and includes a summit crater. This hosts Masaya caldera, formed 2,500 years ago by an 8 km3 (1.9 cu mi) basaltic ignimbrite eruption. Inside this caldera a new basaltic complex has grown from eruptions mainly on a semi-circular set of vents that include the Masaya and Nindiri cones. The latter host the pit craters of Masaya, Santiago, Nindiri and San Pedro. Observations in the walls of the pit craters indicate that there have been several episodes of cone and pit crater formation.
The Irazú Volcano is an active volcano in Costa Rica, situated in the Cordillera Central close to the city of Cartago.
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.
Juan Castro Blanco National Park is a national park, that is part of the Arenal Huetar Norte Conservation Area, in northern Costa Rica.
Arenal Volcano National Park is a Costa Rican national park in the central part of the country, part of the Arenal Huetar Norte Conservation Area. The park encompasses the Arenal Volcano, the most active in the country, which was believed to be dormant until a major eruption in 1968. It neighbors Lake Arenal, which is the site of the country's largest hydroelectricity project, the Lake Arenal Dam.
Poás Volcano National Park is a national park in Costa Rica that covers an area of approximately 65 square kilometres ; the summit of Poás Volcano located within the park is at an elevation of 2,700 metres (8,900 ft). The park was established on 25 January 1971. Depending on conditions, visitors can walk all the way to the edge of the main crater, but on 13 April 2017 the park was closed to visitors due to an explosive eruption on the evening of 12 April. Still further eruptions, including on Easter, 16 April, caused the park to be closed until August 2018.
Irazú Volcano National Park, or in Spanish the Parque Nacional Volcán Irazú, is a National Park in the Central Conservation Area of Costa Rica that encompasses the area around the Irazú Volcano in Cartago Province which incorporates what used to be the Ruben Torres Rojas Forest Reserve now called the Prusia Forest Reserve. The volcano is still active although the last major eruptions were between 1963 and 1965, with occasional minor eruptions and some small lava flows since that time.
A complex volcano, also called a compound volcano or a volcanic complex, is a mixed landform consisting of related volcanic centers and their associated lava flows and pyroclastic rock. They may form due to changes in eruptive habit or in the location of the principal vent area on a particular volcano. Stratovolcanoes can also form a large caldera that gets filled in by a lava dome, or else multiple small cinder cones, lava domes and craters may develop on the caldera's rim.
Cosigüina is a stratovolcano located in the western part of Nicaragua. It forms a large peninsula extending into the Gulf of Fonseca. The summit is truncated by a large caldera, 2 x 2.4 km in diameter and 500 m deep, holding a substantial crater lake. This cone has grown within an earlier caldera, forming a somma volcano. The earlier caldera rim is still exposed on the north side, but has been buried by the younger cone elsewhere.
Barva Volcano is an andesitic stratovolcano complex in central Costa Rica, 22 km north of San José, in Heredia Province. On the eastern side of the mountain is a lake in what was the volcanic crater, called "Laguna de Barva", and on the western side it has three hills on the top which are called "Las Tres Marías". It is located in the small agricultural community of Sacramento.
Rincón de la Vieja is an active andesitic complex volcano in north-western Costa Rica, about 23 km (14 mi) from Liberia, in the province of Guanacaste.
Platanar Volcano is located in the Cordillera Central mountain range. It is part of a complex that covers 900 square kilometres and is dominated by Porvenir Volcano at 2,267 m (7,438 ft). It is located within the Juan Castro Blanco National Park.
A volcanic crater lake is a lake in a crater that was formed by explosive activity or a collapse during a volcanic eruption.
Lake Cote, originally known as Lake Cóter, is a fresh water crater lake located in the northern highlands of Costa Rica. It is currently the largest natural lake in Costa Rica at 1.98-square-kilometre (0.76 sq mi). Its depth varies between 6 and 18 meters.
The Cacho Negro Volcano, in Spanish the Volcán Cacho Negro, which translates as Black Horn Volcano, is an inactive volcano in Costa Rica, situated in the Cordillera Central range near the Barva Volcano and within the Braulio Carrillo National Park.
Lake Hule, which translates to Lake of Rubber, due to the abundance of rubber trees nearby, is a fresh water crater lake located in the northern highlands of Costa Rica. It is part of a complex of lakes comprising Lake Hule, Lake Congo and Lake Bosque Alegre. The lakes are part of the Bosque Alegre Wildlife Refuge.
Lake Botos, is a crater lake located inside the Poás Volcano National Park.
