Eruption at Turrialba, Klyuchevskoy, Piton de la Fournaise and Ubinas.

Following an increase of seismicity from 11.09 to 19h, a new eruptive process began in Turrialba on September 13 from 2:10 local, characterized by an emission of ash and gas that lasted until 6:13. The eruptive plume rose to about 300 meters above the volcano, before spreading to the north-northeast.

In Klyuchevskoy, explosive-effusive eruption continues. The outpouring feeds flows on the flanks east and south-east; on the southeast side, the number of flows increased to five.

At Piton de la Fournaise, two vents remain active, with projections to 15 to 30 meters high. The activity fell slightly since Sunday, in stages, with a low but continuous seismology.
Observers had to brave the cold night, but the show is still beautiful.

In Peru, seismicity has changed at Ubinas since 9 September; volcano-tectonic earthquakes, related to fracturation of rocks, were followed by hybrid earthquakes, associated with magma ascent.

Slow internal pressurization process marks the Ubinas; where fumaroles are observed, reflecting the disruption of the hydrothermal system, which reach up to 500 meters above the crater.
