Activity of the Chaparrastique, Nevado del Ruiz, Turrialba, Colima, Sabancaya and Kilauea.

In El Salvador, the activity of the Chaparrastique has been maintained with slight fluctuations since 14 November. The pulsatile degassing of the main crater is decreasing.
Sulfur dioxide emissions fluctuated between 65 and 1,337 tons / day, in relation to variations in the volcanic seismicity, typical of an open-duct volcanic system.

Turrialba / in Costa Rica and Colima / in Mexico continue their characteristic activity in recent days.
At Turrialba, gas and ash emissions do not exceed 300 meters above the summit and affect the area between Irazu and Turrialba.
The Colima knows for its part an important degassing day

The satellites provide us with interesting images of erupting volcanoes: the Sabancaya in Peru, and the Kilauea / Pu'u O'o in Hawaii.
