The most active volcano in Ecuador experienced another round of explosions, gas emissions, and volcanic tremors in November.

The Sangay volcano, which is steep-sided and glacier-covered, also emitted ash in the beginning of the month.

On a day when the volcanic plume was particularly straight due to southeasterly winds, the Landsat 8 satellite captured this image despite some afternoon cloud cover. The natural-color image was acquired by the satellite’s Operational Land Imager (OLI) on November 5, 2022. The second image is a closer view of the eruption column.

According to the Ecuadoran Geophysical Institute of the National Polytechnic School (IG-EPN), satellites and webcams observed an ash-and-gas plume daily between November 1-8. Plumes generally rose to a height of 1.8 kilometers (1.2 miles) during that period, though they also reported one plume being lofted as high as 8.3 kilometers on November 4, 2022.
