Irazu Volcano National Park
The Irazú Volcano (Spanish: Volcán Irazú) is an active volcano, also National Park Costa Rica, located in the Central Cordillera, near the city of Cartago. The name could come from the combination of "ara" (point) and "tzu" (thunder) or a corruption of Iztarú, which was the name of an indigenous village on the flanks of the volcano.
The "Colossus" as is known this volcano in Costa Rica, has caused major disasters in the past. A detail of the crater rim. The Irazu volcano has several craters, one of which contains Diego de la Haya, a crater with a small green lake of variable depth. Besides Irazu Volcano is the highest active volcano in Costa Rica.
In summer with clear weather, from the top you can see both the Atlantic Ocean and the Pacific Ocean. However, this type of clear days are rare, and the summit of the volcano is generally covered by clouds. The volcano is located within the Irazu Volcano National Park, which spreads across 5,705 acres (2,300 hectares).
Geology
Radioactive dating has shown an age of at least 854,000 years, with peak eruption 570,000 years and the latest active phase of 136,000 years to the present.
The volcano there is a viewpoint from where you can see the lagoon of the volcano, there are occasions that a thick fog covers the entire view, but when the fog clears, you can have an unforgettable view of this beautiful wonder of nature.
Therefore, it is a very touristy place visited by thousands of tourists from around the world.
The national park contains both primary and secondary montane forests and is home to armadillos, owls, rabbits, raccoons, foxes, woodpeckers and hummingbirds.
The Irazu volcano has an area of 500 km2. Subconic has an irregular shape and temperature ranges between 2 and 16 ° C (35 to 64 ° F). It is a stratovolcano with a summit elevation of 3431 meters (11,260 feet). Its five craters are easily differentiated. The most important for its activity are the main crater, which is almost circular with steep walls and measures 1050 meters (3,440 feet) in diameter and 300 meters (980 feet) deep; The Diego de la Haya crater is 600 meters (2,000 feet) in diameter and 100 meters (330 feet) deep. Other craters are Playa Hermosa, La Laguna and Pyroclastic.
The most recent activity includes lava flows with Strombolian and phreatomagmatic explosions. Types include lava basalt and andesite erupted during different events that suggest the volcano is fed by two different magma chambers. Scientists believed that magma pulses mixed into the camera before climbing up a process estimated to take several thousand years.
But volcanologists Columbia University found that the eruption of the Irazu Volcano in Costa Rica in 1963 was probably caused by magma took a nonstop route from the mantle over just a few months. The study authors called the road of hell.
We offer daily tours from San José.
The Botos crater has not erupted for about 7,500 years. Well-marked trails will take you to see the inactive crater. The park is frequently closed to visitors because of sulphuric gas emissions. Over the last decade there have been a number of indications that the volcano is slowly building up towards a new eruption.
