Cotopaxi volcano update: Continuing steam emissions, small explosions
Thursday Oct 29, 2015 15:43 PM | BY: T
Steam emissions and glow from Cotopaxi this morningNo significant changes in the volcano's activity have occurred. According to monitoring scientists from IGEPN, it seems that magma is slowly rising inside an open-conduit system.
During the last week, visual activity mainly consisted in steam and gas emissions reaching 1-2 km height, as well as small explosions in the crater that could only be detected instrumentally. Ash emissions have been minimal. Overall seismic activity has slightly decreased, with averages of 30-50 volcano-tectonic earthquakes (VT) per day. SO2 emissions remained high, fluctuating at values of 2000-5600 tons / day.

No significant changes have occurred during the past days. The activity remains characterized by intense degassing and occasional mild ash emissions mixed into the plume. [more]

The volcano's activity has been similar as during the past weeks. It continues toerupt a weak to moderate steam plume with more or less ash content, rising up to 1.5 km above the summit crater. Occasional weak ash falls have occurred in areas to the west and southwest of the volcano. ... [more]

During the past days, intermittent explosive activity has resumed at the volcano's summit crater. Intense activity on 8 and 9 Oct generated ash plumes that rose up to 1-1.5 km height above the crater and drifted to the west. [more]

Visible activity of the volcano has been relatively low during the past week. Only a strong steam plume mixed with low ash contents has been emitted, but there has been a significant change: incandescence has now become visible from the crater. According to scientists from IGEPN, the glow originates from high-temperature gasses. However, this suggests that magma continues to approach the vent, and that the eruption might now be about to become magmatic. ... [more]

The volcano remains active at low to moderate levels (seismicity and emissions). It continues to produce mild ash emissions that usually drift westwards and rise approx. 1 km from the crater. ... [more]
