Quick Answer
Pumice falling is a sign of a volcanic eruption; evacuate immediately to a safe distance if advised to do so by authorities or if you're within a designated evacuation zone.
Understanding Pumice Tephra
Pumice tephra is a type of volcanic ash that can cause serious hazards. It’s created when superheated lava is quickly cooled, resulting in a lightweight, porous rock that can be blown by the wind and carried long distances. When pumice falls from the sky, it can cause respiratory problems, damage crops, and obstruct water sources.
Identifying Hazardous Conditions
To determine if you should evacuate, pay attention to the following conditions: the intensity of the eruption, the direction and speed of the wind, and the amount of pumice falling. If you’re within 10-15 kilometers (6-9 miles) of the volcano, the risk of ashfall and pyroclastic flows increases significantly. If the eruption is explosive and the wind is blowing towards populated areas, evacuate immediately.
Preparing for Evacuation
When evacuating due to pumice tephra, prioritize your safety and the safety of those around you. Follow the instructions of local authorities and stay informed through reliable news sources. Bring essential items such as food, water, medications, and a first aid kit. If you’re driving, keep windows closed and avoid driving through areas with heavy ashfall, as it can reduce visibility and cause vehicle damage.
