Volcanic eruptions occur when magma from beneath the Earth’s crust escapes through vents. This can result in lava flows, ash clouds, and pyroclastic flows.

Volcanic eruptions occur when magma from beneath the Earth’s crust escapes through vents. This can result in lava flows, ash clouds, and pyroclastic flows. Understanding the Volcanic Explosivity Index (VEI) can help assess potential risks in your area.
Safety Measures During a Volcanic Eruption
-
Evacuate the area if you are in a zone near a volcano.
-
Stay indoors and avoid ashfall.
-
Cover your nose and mouth to protect from inhaling ash particles.
+
Evacuate Immediately: Follow authorities' instructions if you are in a danger zone.
+
Protect Against Ash: Ash is pulverized rock, not wood ash. Wear N95 masks and goggles.
+
Shelter in Place: If caught indoors, close all windows, doors, and fireplace dampers to keep ash out.
+
Avoid Low Ground: Stay away from valleys where lahars (mudflows) and lava travel.
