Volcano
A volcano is a vent which molten rock escapes through to the surface of the earth. An eruption happens when pressure from gases within the molten rock becomes too great. There may be lava flows, flattened landscapes, poisonous gases, flying rock and ash.
Because of their intense heat, lava flows are great fire hazards. Lava flows destroy everything in their path, but most move slowly enough that people can move out of the way.
Fresh volcanic ash, made of pulverized rock, can be abrasive, acidic, gritty, gassy, and odorous. While not immediately dangerous, the acidic gas and ash can cause lung damage to infants, older adults, and individuals with severe respiratory illnesses.
Volcanic eruptions can be accompanied by other natural hazards, including earthquakes, mudflows and flash floods, rock falls and landslides, acid rain, fire, and tsunamis. Even a volcano thought inactive can suddenly erupt. Pay attention to any reports of volcanic activity and be prepared for any possible eruption.

Take Protective Measures
What can I do Before a Volcanic Eruption?

Add a pair of goggles and disposable breathing mask for each member of the family to your disaster kit

Stay away from the immediate area of active volcano sites


What do I do During a Volcanic Eruption?

Evacuate immediately from the volcano area to avoid flying debris, hot gases, lateral blast and lava flow

Be aware of mudflows

Avoid river valleys and low-lying areas

Protection from Falling Ash
Wear long-sleeved shirts and long pants

Use goggles and war eyeglasses instead of contact lenses

Use a dust mask or hold a damp cloth over your face to help with breathing

Stay away from areas downwind from the volcano to avoid volcanic ash

Stay indoors until the ash has settled unless there is a danger of the roof collapsing

Close doors, windows and all ventilation in the house

Clear heavy ash from flat or low-pitched roofs and rain gutters

Avoid running car or truck engines

If you have to drive, keep speed down to 35 MPH or slower
