TUNGURAHUA VOLCANO

The weather has been favorable for visual observation of the volcano during the last weeks. Emissions of gasses with small content of ashes are still occurring, as well as bellowing sounds from the interior. The seismic activity has remained at a level considered low. Mudslides along the flanks have been observed flowing down the gorges on the sides of the volcano. In general it is evident that since the end of January 2005 there is a continuous decrease in the number of explosive events as well as of the energy liberated by them. Actually in 2007 the volcano still making eruption but with the right advice it can be safe to visit Baños.

COTOPAXI VOLCANO

The activity of this volcano remains at a level that is considered as moderate, with tendency to decrease. A series of seismic events have been registered by the instruments, which are related to the movement of fluids within the volcano. Visual observation detects small emissions at the crater, mostly of water vapor, that do not overpass the altitude of the summit. Since the beginning of October, instruments show a widening of the northeastern flank, which has been constant in the last weeks. The Cotopaxi volcano still in activity but it won{t go to erupt in a few years more.

EL REVENTADOR VOLCANO

Explosive events continue to occur, which generate high columns of vapor and gas with variable content of ashes. Some of the explosions generate important acoustic waves – which cause the vibration of windows in the neighborhood– and the emission of incandescent material in the shape of blocks.

The seismic activity of El Reventador is characterized by the generation of bands of tremors, both harmonic and spasmodic of durations that go from various minutes to hours. Ash falls have not been reported in the last weeks.

SIERRA NEGRA VOLCANO (GALAPAGOS)

On October 22, 2005, the Sierra Negra Volcano on Isla Isabela in the Galapagos Islands began erupting. The volcano produced an ash cloud several kilometers high and a lava flow down its northeast flank. Lava flows on the flanks have now stopped and lava is going into the immense crater of Sierra Negra.

Eruptions are common in this volcanically active archipelago, however, this eruption has not endangered any of Isla Isabela’s human inhabitants, or any of the wildlife for which the Galapagos is famous.
