Volcanic eruption and ashfall safety for travellers: protect your breathing, shelter from ash, and what to do before, during and after an eruption.
Before: get prepared
Know your area’s risk from volcanic eruption.
Ask local emergency management for evacuation and shelter plans, and for potential means of protection from ash.
Learn about community warning systems by signing up for a free service called the Volcano Notification Service (VNS) that sends notifications about volcanic activity.
Get necessary supplies in advance, including nonperishable foods, cleaning supplies and water for several days, in case you have to evacuate immediately or if services are cut off. Keep in mind each person’s specific needs, including medication. Do not forget pets’ needs for medication and food.
Consult your doctor if you have existing respiratory difficulties.
Practice a communication and evacuation plan with everyone in your family. Have a plan for pets and livestock.
Have a shelter-in-place plan if your biggest risk is from ash.
Keep important documents in a safe place. Create password-protected digital copies.
Find out what your homeowner’s insurance policy will cover when a volcano erupts.
During: stay safe
Listen to alerts. The Volcano Notification Service provides up-to-date information about eruptions.
Follow evacuation orders from local authorities. Evacuate early.
Avoid areas downwind, and river valleys downstream, of the volcano. Rubble and ash will be carried by wind and gravity.
Take temporary shelter from volcanic ash in the location where you are, if you have enough supplies. Cover ventilation openings and seal doors and windows.
If outside, protect yourself from falling ash that can irritate skin and injure breathing passages, eyes and open wounds. Use a well-fitting, certified face mask, such as an N95.
Avoid driving in heavy ash fall.
After: recover safely
Listen to authorities to find out when it is safe to return after an eruption. Stay indoors until authorities say it is safe to go outside.
Send text messages or use social media to reach out to family and friends. Phone systems often are busy after a disaster. Only make emergency calls.
Avoid driving in heavy ash. Driving will stir up volcanic ash that can clog engines and stall vehicles.
Avoid contact with ash if you have any breathing problems. People with asthma and/or other lung conditions should take precaution in areas with poor air quality, as it can worsen symptoms.
Do not get on your roof to remove ash unless you have guidance or training. If you have to remove ash, then be very careful as ash makes surfaces slippery. Be careful not to contribute additional weight to an overloaded roof.
Wear protective clothing and a mask when cleaning up. Children should not help with cleanup efforts.
