Poás is a broad volcano with a summit area containing three craters and is one of the most active volcanoes of Costa Rica. This photo from the east shows a plume rising from the active summit crater, which has been the site of frequent phreatic and phreatomagmatic eruptions since 1828, and the lake filled Botos crater to the left.

Resumen geológico

The broad vegetated edifice of Poás, one of the most active volcanoes of Costa Rica, contains three craters along a N-S line. The frequently visited multi-hued summit crater lakes of the basaltic-to-dacitic volcano are easily accessible by vehicle from the nearby capital city of San José. A N-S-trending fissure cutting the complex stratovolcano extends to the lower N flank, where it has produced the Congo stratovolcano and several lake-filled maars. The southernmost of the two summit crater lakes, Botos, last erupted about 7,500 years ago. The more prominent geothermally heated northern lake, Laguna Caliente, is one of the world's most acidic natural lakes, with a pH of near zero. It has been the site of frequent phreatic and phreatomagmatic eruptions since an eruption was reported in 1828. Eruptions often include geyser-like ejections of crater-lake water.

Resumen de Wikipedia

Resumen en inglés

The Poás Volcano, is an active 2,697-metre (8,848 ft) stratovolcano in central Costa Rica located within Poas Volcano National Park. It has erupted 40 times since 1828, with a strong eruption in 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.
