The Volcanic Explosivity Index (VEI) is a logarithmic scale used to measure the explosiveness of volcanic eruptions. Ranging from 0 to 8, it helps classify eruptions based on the volume of erupted material, eruption cloud height, and qualitative observations. The VEI Scale is crucial for understanding the potential impact of eruptions, particularly when classifying different eruption styles and assessing the features associated with specific volcanic structures.
congrats on reading the definition of VEI Scale. now let's actually learn it.
