In the last 24 hours, the activity of Fuego showed an increase with explosions, a plume of 5000-5500 m. asl with dispersion over 15 km towards S-SE sector, a lava flow descendant over 600 meters towards the barranca Las Lajas and a pyroclastic flow of about 3,000 meters. Ash falls were reported on Morella, Santa Sofia, La Rochella, and Panimache I & II, with a probability of extension.
During the day of 1 March, the explosions continued with a plume rising to 6,000 meters asl, deriving following a change of winds towards northeastern sector over 40 km.
The lava flow was maintained and concerns the ravines Las Lajas and El Jute, reaching a length of 2,000 meters; The avalanches of blocks concern mainly the barranca Honda.

An overview of Colima, on 29 February, confirms the growth of the intracrateric dome and an increase of fumerolian activity in the southeast sector.
The Civil Protection reported in a statement : " in the last days, there was seismic activity associated with the rise of magma, and characterized by a very variable fumarole, typical of ascension of materials".
The exclusion zone is maintained at 5 km from the crater, with an extension to 12 km for the barranca Montegrande, for risk of pyroclastic flows and lahars.

In Tungurahua, the number of emission tremor episodes, explosions, and fluid movements related to earthquakes has increased since February 27.
Ash emissions reach 4,000 meters above the crater. On the night of 29 February to 1 March, lava fountains are noticed, with emission of ballistic blocks falling 1,500 meters below the crater. Several small pyroclastic flows are reported in the ravines Juive, Mandur, Achupashal and Romero.
Sulfur dioxide emissions reach 1,544 tons / day (Bayushig station) against 209 tonnes / day on 25 February.
