Holy Stromboli! Views of Mt. Etna’s Eruptions
February 24, 2021

The pastel imagery above is an Ash RGB product captured by Europe’s Meteosat-11 satellite on Feb. 21 and Feb 23, 2021. Based upon infrared channel data, the product is designed to detect ash and sulphur dioxide from volcanic eruptions, which later can be used to warn aviation and other municipal authorities. 

Since Feb. 16, the satellite—operated by NOAA’s European partner EUMETSAT—has seen four different "strombolian", or mild-to-moderate, eruptions from the famous Mt. Etna volcano in the Italian island of Sicily. The volcano, which is well known for its frequent eruptions, spewed out ash and sulfur dioxide into the atmosphere throughout the past week.
