Turrialba volcano (Costa Rica): activity updates and eruption news

Turrialba volcano (Costa Rica), activity update: strongly increased fumarolic activity

Saturday Dec 15, 2007 13:03 PM |

The volcanic unrest at Turrialba seems to intensify, and signs of a possible new eruption in the near to medium future are getting stronger: According to OVSICORI-UNA a gas-and-steam plume from Turrialba rose to an altitude greater than 5.3 km (17,400 ft) a.s.l. on 5 December. Fieldwork confirmed an unusual output of gas from several fumaroles along the S outer wall. Areas burned by acute acidification have extended in the last month. Pastures turned yellowish near the upper areas, and native and exotic tree species were impacted as well as birch tree patches along most drainages. Within the W crater, temperatures of fumaroles reached 280 degrees Celsius and native sulfur was present.
