🧰 What to do
Before
- •Know your community's evacuation plan and routes
- •Prepare goggles and N95 masks for ashfall
- •Keep vehicles fueled and a kit ready if near an active volcano
During
- •Evacuate if ordered; ash and gases can be deadly
- •If staying: close windows/doors/vents, wear a mask outdoors
- •Avoid river valleys and low areas (lahar/mudflow paths)
After
- •Avoid ashfall driving — ash damages engines and cuts visibility
- •Clear heavy ash from roofs carefully (wet ash is very heavy)
- •Wear a mask during cleanup; keep ash away from children
