Turrialba Eruption

Standard

Taking centre stage on many eruption blogs this week has been Costa Rica’s Turrialba volcano. It is one of the countries largest active volcanoes along side its neighbour Irazu.

Activity has been at moderate levels for a few weeks now with small explosions recorded daily and small lahars recorded on May 7th. At the begining of the week tremors appeared to decrease in both amplitude and frequency and the volcano appeared to be quietening down.

This quickly changed when a single explosion in the early hours of Thursday morning ejected a cloud of volcanic ash, gas and rocks from the volcano 30 miles east of the capital San Jose and saw local schools and businesses closed the next day. These have all since reopened however the alert remains at
