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.

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.
