Staying safe during a volcanic eruption means acting fast, staying calm, and following official instructions at every step.

What to Do During a Volcanic Eruption (Quick Scoop)

In any volcanic emergency, listen to local authorities first. If their instructions differ from anything you read here, follow them.

1. Immediate Actions When an Eruption Starts

If authorities issue a warning or evacuation order

  • Leave immediately if told to evacuate; do not wait to “see what happens.”
  • Take your emergency kit (water, food, medications, flashlight, radio, copies of important documents).
  • Wear sturdy shoes, long sleeves, and long pants to protect your skin.
  • Use roads and routes recommended by officials; avoid shortcuts through river valleys or low-lying areas (these can become mudflow paths).

If you are outside when it erupts

  • Go indoors as quickly and safely as possible to avoid ash, debris, and gases.
  • If you are near a stream or river and notice rising or muddy water, move quickly uphill—this can signal a mudflow (lahar).
  • If caught in a rockfall, roll into a ball and protect your head and neck with your arms.
  • Avoid areas downwind and downstream from the volcano, where ash and mudflows are more likely.

2. Staying Safe Indoors During Ashfall

Ash can cause breathing problems, eye irritation, and roof damage, so your focus is on sealing the building and protecting your lungs.

Seal and protect your home

  • Close all windows, doors, and vents; block gaps with damp towels or cloths.
  • Keep fans, air conditioners, and ventilation that pull outside air turned off if possible so you don’t bring ash indoors.
  • Disconnect gutters and downpipes to stop ash clogging the drainage system; if you collect rainwater, disconnect the storage tank to avoid contamination.

Protect your health from ash

  • Stay inside as long as it is safe to do so, especially if you have asthma, COPD, or other breathing problems.
  • If you must go outside:
    • Wear a proper mask (N95-type) or at least a damp cloth or handkerchief over your nose and mouth.
* Wear goggles; use eyeglasses instead of contact lenses, which can trap ash and scratch your eyes.

* Wear long sleeves, long pants, hat, and closed shoes to keep ash off your skin.

Communication and power

  • Use a battery-powered or hand-crank radio or your phone (with battery pack) to follow local emergency broadcasts.
  • Keep phone calls short and for urgent needs so networks stay open for emergencies.

3. Evacuation and Movement: Key Do’s and Don’ts

When moving through an ash-covered area

  • Drive only if absolutely necessary; ash can make roads slippery, reduce visibility, and damage vehicles.
  • If you must drive:
    • Go slowly, use headlights, and keep distance from other vehicles.
    • Avoid driving in heavy ashfall if you can safely wait it out.

Avoid high-risk zones

  • Stay out of restricted or exclusion zones marked by authorities; these areas may face lava flows, pyroclastic flows, and heavy ash.
  • Avoid bridges and low-lying areas if there is any sign of mudflows (fast-moving, concrete-like floods of ash and debris).

4. Protecting Family, Children, Elderly, and Pets

Family and vulnerable people

  • Talk through the plan with your family ahead of time so everyone knows what to do and where to meet.
  • Help infants, elderly family members, and people with disabilities put on masks, goggles, and extra clothing.
  • Keep spare inhalers and medications ready for anyone with respiratory disease.

Pets and animals

  • Bring pets indoors; ash can harm their lungs and eyes as well.
  • Keep extra water and food for them; avoid letting animals graze on ash-covered grass.

Phase What to Do
Before eruption Prepare an emergency kit, plan evacuation routes, follow local volcano alerts and education campaigns.
During eruption (general) Follow all official instructions, be ready to evacuate, avoid downwind and low-lying areas.
During ashfall Stay indoors with windows and doors closed; wear masks and goggles if you go outside; cover skin.
During evacuation Leave quickly but calmly with emergency supplies; use designated routes; help vulnerable people.
After eruption Wait for “all clear” from authorities; clean ash carefully with masks and goggles; check roofs for load.

6. A Short, Realistic Scenario

Imagine you’re at home and hear on the radio that a nearby volcano has started erupting and ashfall is coming toward your town. You quickly close windows and doors, block the gaps with damp towels, and switch off the air intake systems. You grab your pre-packed bag with water, snacks, medications, and radio, and you help your children put on masks and goggles. When authorities announce an evacuation for your area, you put on sturdy shoes and long clothes, load your family and pets into the car, and follow the recommended route away from the volcano, avoiding river valleys and low-lying roads. You keep listening to updates until you reach a safe shelter and wait for further instructions.

7. Quick Checklist (What to Do During a Volcanic Eruption)

  1. Follow official alerts and instructions at all times.
  1. Evacuate immediately if told to; do not delay.
  1. If outside, seek indoor shelter quickly and avoid low-lying and downwind areas.
  1. Protect lungs and eyes with masks and goggles; cover skin with long clothing.
  1. Use a battery-powered radio or phone to get updates; keep non-urgent calls to a minimum.
  1. Be alert for mudflows near rivers and streams; move uphill if water rises or looks muddy.
  1. Help children, elderly people, and those with disabilities or health issues first.

TL;DR: During a volcanic eruption, stay informed, stay covered, avoid ash and low-lying areas, and always follow official evacuation and safety instructions—even if the volcano looks “quiet” from where you are.
