Tenorio Volcano (Spanish: Volcán Tenorio) is an inactive andesitic stratovolcano in the southeasternmost part of the Cordillera de Guanacaste volcanic mountain range in northwestern Costa Rica.[1][2] It is the main geographical feature of the eponymous Tenorio Volcano National Park.[3]

Geology

It is composed of four volcanic peaks and twin craters Tenorio and Montezuma.[4] The formation occupies 225 square kilometres (87 sq mi).[5]

Tenorio, the principal peak, has three craters in the central cone, while Montezuma, to the north, has two.[5] Tenorio's summit is 1,916 metres (6,286 ft) high,[6] while Montezuma's is 1,513 metres (4,964 ft).[7] Lava flows descend to the northeast from Tenorio's northwestern-to-southwestern flank.[6] The Biguana lava domes lie on the northern flank[6] at 700 metres (2,300 ft).[7] The volcanic cones Cerro Barrera and Olla de Carne are at elevations of 720 metres (2,360 ft) and 454 metres (1,490 ft), respectively.[7] The southeastern flank features a number of small, inactive parasitic cones.[1]

There are no known eruptions during the Holocene epoch (about 11,700 years ago to the present).[6] Weak earthquakes were detected in 1997 and 1998, the latter consisting of 170 with magnitudes ranging from 0.9 to 3.3.[8]

Feasibility of geothermal power generation

The Instituto Costarricense de Electricidad (Costa Rican Institute of Electricity) conducted an evaluation of the country's geothermal resources between November 1987 and October 1988; Tenorio was selected as one of three high-priority areas.[9] In 1999–2000, two exploratory wells were dug to evaluate its potential as a source of geothermal power, with disappointing results.[10][11]
