Costa Rica Poas Volcano

Poas Volcano

The Poas Volcano, located in the National Park of the same name, is one of the most active volcanoes in Costa Rica. You can lodge nearby in hotels and lodges that take advantage of the great weather near this protected area. The volcano stands 8,884 feet high, and contains three craters and several lake-filled vents. The summit crater, which is the most widely visited, contains two lakes: Botos, which is cold and has clear water, and another, geothermally heated one, which is one of the most acidic lakes in the world. There are historical records of Poas volcano’s action that go as far back as 1828 (of course, this does not include the volcanic activity that occurred thousands of years ago), but the last known eruption happened in 1996. The densely vegetated cone presents geyser-like eruptions of crater-lake water, as well as plumes of steam. Looking to the left of the Poas Volcano Costa Rica crater, you can see the detrimental effects of the volcanic gases that cause a localized form of acid rain. For several kilometers downwind from the crater, the vegetation is brown and dying.

With a diameter of 1.5 km., Poas Volcano’s crater is reportedly one of the widest in the world. If it is clear enough to see to the bottom of the 984 foot deep crater, you may observe some type of activity, ranging from fumaroles, to bubbling emissions on the surface of the small rain-filled lake, to actual geyser-type eruptions, but it is constantly changing. During the early 1990s, there was enough geyser activity to cause the lake to lose its water by the end of the dry season; this resulted in increased gaseous emanations that forced the protected area to close on a few occasions. More recently, the opposite has occurred at this historical site in Costa Rica. Intense rainfall during the first months of 2005 raised the level of the hot lake by 13 feet (a record since starting to track the level of this lake in 1978), and increased its area by 20 percent. This caused some fumaroles to be covered by water, which started presenting constant bubbling at the Poas, Costa Rica.
