Activity report of the Turrialba volcano
June 3, 2016, 5:00 p.m.
Today eruptive activity continues, with passive ash emissions, and some major impulses that took place at: 10h35, 11h20, 13h55 and 15h20.
The seismic activity is characterized by a spasmodic tremor (variable amplitude) which began at 22:10 on June 1, with a downward trend today as compared to the night of 1 to 2 June
Field observations indicate that the plume reaches 1000m above the volcano in the morning. The models AERMOD and Ash3D anticipate dispersion of ash to the North and the Northeast.
Ash falls were reported in:
Limón Cariari, Pococí, Jiménez, Siquirres, Guácimo, Limón Centro.
A slight smell of sulfur is felt in the Siquirres region , Pococí, Guápiles, Guácimo.
A flyby of the Turrialba volcano evidences the disappearance of flora on the slopes of volcano due to ashfall. The grass, plants and trees that used to be on the west side of the Turrialba volcano no longer exist. A change in wind is now beginning to affect the south side as well.
The ash and gases expelled by the volcano since 2010, when the volcano reactivated for the first time, until recent weeks, caused the disappearance of the flora. This was corroborated by a flyby by the National Emergency Commission (Comisión Nacional de Emergencias – CNE) on Saturday, May 28.
