In El Salvador, the Chaparrastique / San Miguel is the seat of an important degassing, suggesting the existence of a deep hot mass in motion and releases of magmatic gas, exacerbated by an high humidity.

Seismicity shows a gradual downward trend and decompression of the system.

Access to the top is not recommended because of the danger constituted by the gases and the possibility of an explosion. The alert level remains Orange.

At Etna, the new Southeast Crater / NSEC shows a plume of steam, appearing more important because of an increased atmospheric humidity, illustrated by the photo of Gio Giusa.
