When volcanoes erupt, molten lava, poisonous gases, and flying rocks can travel many miles away. Volcanic ash and acid rain can fall hundreds of miles downwind. Volcanoes can be incredibly destructive to your home and dangerous to your family. In addition to the direct hazards, an eruption can be accompanied by landslides, mudflows, flash floods, earthquakes, and tsunamis.

If you live anywhere near an active or dormant volcano, you should be prepared to evacuate at a moment’s notice as eruptions are not always predictable. The danger area around a volcano covers approximately a 20-mile radius; however, some danger may exist 100 miles or more from a volcano.

How to Prepare
  1. Verify and update official contact information in the Marine Corps Enterprise Mass Notification System (eMNS), and register all cell phones, home phone, email addresses, etc. in eMNS
  2. Know whether your area has the potential for volcanic eruptions.
  3. Know the evacuation zones.
  4. Make a written family evacuation plan.
  5. Make a written emergency communication plan in case family members are separated.
  6. Stay away from volcano sites that show signs of activity.
  7. Build an emergency kit that includes goggles and breathing masks.

    • If you are caught in a rock fall, curl up in a tight ball to protect yourself.
    • Be aware of mudflows and flooding if you are near a stream.
  • Protect yourself from hazardous falling ash:
    • Stay away from areas downwind of the volcano.
    • Wear long-sleeved shirts and pants.
    • Wear goggles to protect eyes.
    • Wear a mask or use a damp cloth over your face to minimize breathing in ash.
