The Poas Volcano - PHOTOGRAPHER COMMENT

Volcán Poás, as it is known locally, has been erupting for the past 11 million years, most recently between 1952 and 1954. The 300 metre deep crater is filled with bluish water and continually spews out steam and boiling sulphurous gases. Claimed by the Costa Ricans to be the world's largest geyser, it is one of the most visited volcanos in Costa Rica. This is the view from the public viewing platform, and when conditions are considered safe, it is sometimes possible to follow a route around the crater.

The Poas Volcano - FURTHER INFORMATION

The Poás Volcano is in central Costa Rica in Poas National Park (Parque Nacional Volcán Poás). The volcano is one of the largest active craters in the world, about one mile in diameter. Thousands of people every year come to the Poás Volcano, making it one of the most popular tourist attractions in the Alajuela Province of Costa Rica. The eruptions of the Poás Volcano are 'Phreatic Eruptions'. This means that they are explosive volcanic eruption caused by the interaction of water and heated volcanic rocks. The resulting explosions can eject material about 1,500 feet (500 m) above the lake. These kind of eruptions do not involve magma, unlike the volcanoes on Hawaii Island. This panoramic photograph was taken from the public viewing platform at the edge of the crater.

The main crater is 950 feet (289 m) deep. This crater is still active with frequent geyser and lava eruptions. The last major eruptions were between 1952-54, though Poas has erupted at least 39 times since 1828 and remains in a continuous state of moderate activity. Near the active crater of the Poás Volcano are lakes of molten sulfur, the only examples of their kind in the world.

The park also has two more craters, Von Frantzuis crater, which is extinct, and the Botos crater. The Botos crater has not errupted for about 7500 years and now contains a crater lake.
