The V-Scale is a measurement system used to assess the severity of volcanic eruptions. It ranges from V0 to V5, with V0 indicating a non-explosive event and V5 representing a catastrophic eruption. This scale helps scientists and emergency responders understand the potential impact of an eruption on nearby communities and the environment. The V-Scale considers various factors, including the volume of erupted material and the height of the eruption column. By categorizing eruptions, the V-Scale aids in risk assessment and preparedness, allowing for better planning and response strategies in the event of a volcanic crisis involving volcanoes like Mount St. Helens or Kilauea.
