The Poás Volcano ( Spanish : Volcán Poás ), 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.
14-467: There are two crater lakes near the summit. The northern lake is known as the Laguna Caliente ("hot lagoon") and is located at a height of 2,300 m in a crater approximately 0.3 km wide and 30 m deep. It is one of the world's most acidic lakes. The acidity varies after rain and changes in volcanic activity, sometimes reaching a pH of almost 0. The bottom of this lake is covered with

Business owners described the negative financial impacts the volcano park closure were causing, and Solis released a video in Spanish and English urging potential tourists to visit the nearby community shops and restaurants. He also promised emergency agencies would continue to make updated reports on
56-445: A layer of liquid sulfur. Acidity, lake temperature fluctuations, and a complex, toxic sulfur and iron chemistry (conjectured to be like conditions on early Earth and Mars) limits aquatic life to a specially-adapted Acidiphilium bacteria. Above ground, acid gases create acid rain and acid fog, causing damage to surrounding ecosystems and often irritation of eyes and lungs. Lake Botos , the southern lake, fills an inactive crater, with

The body feathers of both sexes are a mixture of bronze and green iridescent color, with neither sex possessing the beard typically found in wild turkeys. Tail feathers of both sexes are bluish-grey with an eye-shaped, blue-bronze spot near

In respect of it being 'an iconic and type example of an arc shield-like massive stratovolcano and type example of an active crater lake complex', the International Union of Geological Sciences (IUGS) included 'The Poás volcano' in its assemblage of 100 'geological heritage sites' around the world in a listing published in October 2022. The organisation defines an IUGS Geological Heritage Site as 'a key place with geological elements and/or processes of international scientific relevance, used as

There was also an eruptive activity in 2009 involving minor phreatic eruptions and landslides within the northern active crater. Poás eruptions often include geyser -like ejections of crater-lake water. On February 25, 2014, a webcam from the Volcanological and Seismological Observatory of Costa Rica (OVSICORI) captured

This ocellated turkey was photographed near Tikal in the Petén region of Guatemala. Photograph credit: Charles J.

140-462: The eruption. As of September 1, 2018, the National Park has re-opened with limited access and revised regulations. Visitors are required to make an online reservation to enter the park and the number of visitors and time allowed at the crater is limited. Only the main crater observation area is open as of September 2018. As of April 2023, while some adjacent trails remain closed, the trail to

On May 17, 1953, an eruption occurred that started a cycle and lasted until 1956. At least two people were reported missing in this incident. Poás was near the epicenter of a 6.1-magnitude earthquake in January 2009 that killed at least forty people and affected Fraijanes , Vara Blanca , Cinchona (the most affected area),

The Union advance made contact with Confederate troopers the next morning. The Confederates fell back to an elevation known as Reed's Mountain. Blunt continued to pursue after the Confederates abandoned Reed's Mountain, but his leading elements ran into an ambush. The Confederates then presented

Poás is one of the 9 volcanoes currently monitored by the Deep Earth Carbon Degassing Project . The project is collecting data on the carbon dioxide and sulfur dioxide emission rates from subaerial volcanoes . On April 9, 2017, National Park officials placed restrictions on visitors at Poas due to an increased volume of toxic gases at
196-480: The summit crater. An explosion on April 12 caused the decision to close the park for visitors for a "temporary” time. Some nearby residents were also evacuated because of the activity. On April 14, 2017, two eruptions at 07:39 and 07:57 created an over three kilometer ash and vapor column. Further explosions occurred after 2 days, in April 16.
