Volcanoes

Volcanoes

Active volcanoes are rare in the United States, but they can be deadly and have far-reaching effects. Lava flows are not the only danger they pose. During an eruption, a cloud of abrasive ash and toxic gas is blown miles from the volcano. Mudflows, landslides, flash floods and fires also often accompany eruptions.

Before an Eruption

·         If you live in a known volcanic hazard area, purchase goggles and disposable breathing masks for every family member.

·         Plan out primary and secondary evacuation routes.

During an Eruption

·         Stay or get away from the volcano. Stay upwind of the blast to avoid volcanic ash.

·         Watch for mudflows—look upstream before crossing a bridge.

·         Remain indoors until the ash has settled. Close doors, shut windows and seal all ventilation to keep ash out.

·         Breathe through a mask or cloth if you are caught in ash.

After an Eruption

·         Shovel ash from roofs and gutters—it is heavy and can cause a collapse.

·         If you are in an area of ash, wear a long-sleeved shirt and long pants, a facemask and goggles.

·         Do not attempt to drive through ash unless it is necessary. Ash can clog engines and stall vehicles, and it will damage moving parts.
