During the afternoon and night of 20 September, the activity remained at Turrialba with small eruptions and plumes rapidly dispersed toward the northwest.
On September 21, the eruptions are continuing with emissions for 20 to 35 minutes and plumes amount to 600-700 meters, with dispersion to the "Valle Central", where we noted a smell of sulfur and ash falls.
From 9:48, there has been a larger eruption.
