Ringkasan geologi
Turrialba, the easternmost of Costa Rica's Holocene volcanoes, is a large vegetated basaltic-to-dacitic stratovolcano located across a broad saddle NE of Irazú volcano overlooking the city of Cartago. The massive edifice covers an area of 500 km2. Three well-defined craters occur at the upper SW end of a broad 800 x 2200 m summit depression that is breached to the NE. Most activity originated from the summit vent complex, but two pyroclastic cones are located on the SW flank. Five major explosive eruptions have occurred during the past 3500 years. A series of explosive eruptions during the 19th century were sometimes accompanied by pyroclastic flows. Fumarolic activity continues at the central and SW summit craters.
Ringkasan Wikipedia
Ringkasan InggrisTurrialba Volcano is an active volcano in central Costa Rica that has been eruptive in recent years including 2016 and in January, March, and April 2017. Visitors used to be able to hike down into the main crater, but increased volcanic activity in 2014–17, resulting in large clouds of volcanic ash, led to the closure of the surrounding Turrialba Volcano National Park. However, with the eruptions subsiding, the park and access to the volcano reopened on December 4, 2020.
