Summary
[edit]DescriptionAsh from Cerro Hudson, Chile.png |
English: Ash from Cerro Hudson stains the snow in this natural-color image from October 31, 2011. Located in southern Chile, the volcano has a history of violent eruptions, often accompanied by flows of mud, melted snow, and ash called lahars.
SERNAGEOMIN, the Chilean National Geology and Mining Service, reported that Cerro Hudson began to stir on October 25 with a series of earthquakes deep beneath the volcano. The shape of the seismic waves indicated the movement of fluid, likely magma. In the following days, the earthquakes continued and modest plumes rose up to 7.5 kilometers (4.7 miles) above the volcano. The plumes were mostly steam, with some ash. As of October 31, the activity was characteristic of superheated water moving through the upper reaches of the volcano, rather than the eruption of fresh lava. This image was acquired by the Moderate Resolution Imaging Spectroradiometer (MODIS) aboard the Terra satellite. References Klemetti, Erik. (2011, October 31).
