Tefraa

Tefraa is a term used in the context of volcanic activity to describe the fine ash and dust particles that are ejected from a volcano during an eruption. These particles are typically less than 2 millimeters in diameter and can be carried great distances by wind, forming a layer of ash on the ground. Tefraa is a significant hazard to human health and infrastructure, as it can cause respiratory problems, damage buildings, and disrupt transportation and communication systems. The size and composition of tefraa can vary depending on the type of volcano and the intensity of the eruption. Volcanologists study tefraa to better understand volcanic processes and improve hazard assessment and mitigation strategies.
