Ashfall

Ashfall refers to the deposition of volcanic ash following an eruption. When a volcano erupts, it releases ash and small rock particles into the atmosphere. These can be carried by winds over long distances and eventually fall back to the ground, covering landscapes, buildings, and ecosystems. This ash can disrupt air travel, damage machinery, and pose health risks to humans and animals. In some cases, like the 1980 Mount St. Helens eruption, ashfall can significantly alter the environment and impact local communities for years. Understanding ashfall is important for preparedness and response to volcanic activity.
