At Turrialba / Costa Rica, the activity continued on 28 September.
To 0:5 p.m. at the same date, the volcano accumulating 52 hours of sustained activity.

The persistence of the eruption is due to the process of fragmentation and flow of gas within the volcano. The ash falls affect the north of Central Valley, winds now at northwest.
