Turrialba Volcano is an active volcano in central Costa Rica that has been explosively eruptive in recent years including 2016{{cite web|url=http://www.ticotimes.net/2016/09/19/turrialba-volcano-explosion|title=UPDATE: Eruption of Turrialba Volcano closes airport, launches ash, rocks 4 km high|date=19 September 2016}} and in January, March and April 2017.{{cite web|url=http://www.ticotimes.net/2017/03/29/turrialba-volcano-ash|title=Ashes from Turrialba Volcano's explosions reach San José, Heredia|date=30 March 2017}}{{cite web|url=http://www.ticotimes.net/2017/01/05/turrialba-update|title=UPDATE: Green alert declared as Turrialba Volcano ashfall intensifies|date=5 January 2017}}{{cite web|url=http://www.ticotimes.net/2017/01/30/turrialba-volcano-costa-rica-3|title=Costa Rica's Turrialba Volcano resumes vapor, ash explosions|date=31 January 2017}}{{cite web|url=http://news.co.cr/turrialba-volcano-near-cartago-costa-rica-back-action-calm-spell/58805/|title=Turrialba Volcano Near Cartago, Costa Rica Back in Action After Calm Spell - Costa Rica Star News|date=3 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.{{cite news|last1=Zúñiga|first1=Alejandro|title=Costa Rica announces reopening of Turrialba Volcano National Park|url=https://ticotimes.net/2020/11/19/costa-rica-announces-reopening-of-turrialba-volcano-national-park|access-date=19 November 2020|work=The Tico Times|date=19 November 2020}}{{Cite web|url=https://ticotimes.net/2020/12/05/after-eight-years-turrialba-volcano-national-park-reopens-to-the-public|title = After eight years, Turrialba Volcano National Park reopens to the public -|date = 5 December 2020}}

The stratovolcano is {{convert|3340|m|ft|0|abbr=on}} high and is about 45 minutes from the Atlantic slope town of Turrialba. The summit has three craters, the largest of which has a diameter of {{convert|50|m|abbr=on}}.{{cite web|last=Stater|first=Adam|title=The Turrialba Volcano's Craters|url=http://www.anywherecostarica.com/attractions/national-park/turrialba-volcano}}

Turrialba is adjacent to Irazú and both are among Costa Rica's largest volcanoes. Turrialba has had at least five large explosive eruptions in last 3500 years. The volcano is monitored by the Deep Earth Carbon Degassing Project.{{cite web|title=DECADE Installations at Turrialba and Poás|url=https://deepcarbon.net/feature/decade-installations-turrialba-and-poás#.V-ltH2MomXh|website=Deep Carbon Observatory|access-date=26 September 2016}}

On clear days both the Pacific Ocean and Caribbean Sea can be seen from the summit. Below the summit is a mountain range and montane forest, with ferns, bromeliads, lichens and mosses. Most of the forest is either primary or secondary forest.{{cite web|last=Stater|first=Adam|title=Forest Types, Turrialba Volcano|url=http://www.anywherecostarica.com/attractions/national-park/turrialba-volcano}}

The volcano is named after its canton, Turrialba, in Costa Rica's Cartago Province. There is no clear consensus on the origin of the name Turrialba, but historians disagree with attempts to attribute the name to the patronym Torrealba (from Aragon in Spain) or from the Latin Turris alba (white tower). The general consensus is that Turrialba derives from the local Indian (Huetar language), but there is no agreement on its actual roots.

Activity

  • During the 19th century, the volcano erupted and emitted ash several times (1847, 1853, 1855, 1859, 1866), producing pyroclastic flows.
