UPDATE: 4:11 PM – The Turrialba continues its activity, with a four eruption, the largest since 1996, at 3:3o PM, the ash reaching a height of 1.000 metres (1 kilometer).  Experts believe the activitiy will continue into Friday.

QCOSTARICA –  Volcanic activity at Turrialba continues, the National Seismological Network (Red Sismológica Nacional – RSN) records the third eruption in the colossus and an emanation of large amount of ash. The last eruption occurred a few minutes ago at about 2:50pm this afternoon.

Mauricio Mora, volcanologist at the RSN informed Thursday that the observed dark ash could suggest the presence of a shallow magma body, giving evidence of the presence of magmatic material.

The first eruption at the Turrialba was recorded around 11:00 am today, a second at 1:48 pm and the third at 2:50 pm.

On site are experts to evaluate the new cyle of volcanic activity, including volcanologist Raúl Mora, who reported hearing loud explosions that accompanied the activity of the colossus.

Mora said the ash emission have reached the Central Valley, including areas like La Sabana on the west side of San José, though with greater intensity in areas like San Pedro (east side) where significant accumulation is being recorded.

Geoffroy Avard, volcanologist at the Observatorio Vulcanológico y Sismológico de Costa Rica  (OVISCORI) said that after the last eruption, the activity is continuous and ash plumes are passing over the Irazu volcano and reaching the Central Valley.
