Barva Volcano is an andesitic stratovolcano complex in central Costa Rica, 22 kilometres (14 mi) north of San José, in Heredia Province.[1] It is the highest point in Braulio Carrillo National Park at 9,534 feet (2,906 m).[2][3] One source states that it is the largest volcano in Central America by area and volume, being about 40 kilometres (25 mi) in diameter.[4]
Geology
[edit]The volcano rests on the Panama tectonic microplate.[5]
It has multiple peaks, with the three principal summits visible from the Central Valley given the name "Las Tres Marías" ("The Three Marys") by the locals.[1] There is a 2-by-3-kilometre (1.2 by 1.9 mi) crater[1] and "at least a dozen eruptive centers on its summit and several satellite cones on its northern and southern flanks."[6] The central and northwestern summits are made up of four cones, while the southwestern peak has at least four.[7] It has a slope angle of around 20°.[4]
One of the main craters has a lake called Laguna de Barva (Barva Lagoon) at an altitude of 8,228 feet (2,508 m), an area of 9,000 square metres (97,000 sq ft), a depth of around 7.7 metres (25 ft)[1] and spanning 70 metres (230 ft).[8] To its north, there is another volcanic crater lake, Lake Danta, spanning 500 metres (1,600 ft),[8] at around the same altitude.[9]
There are lava flows on the southern side of the volcano, with the latest, the Los Angeles flow originating from the Cerro Redondo cone,[9] almost reaching the city of Heredia.[10] The lava consists of andesites, olivine basalts, and dacites.[9][7]
Cacho Negro Volcano is part of the Barva Volcano complex.[1]
The last confirmed eruptive activity at Barva Volcano has been dated to 6,050 ± 1000 years ago.[1] There were reports of eruptions in the 1760s and in 1867, but investigations at the summit did not find evidence to confirm the reports.[1]
