Volcanoes generate a wide variety of phenomena that can alter the earth’s surface and atmosphere endangering people and property.

Before a volcanic eruption:

• Plan ahead. Have emergency supplies, food and water stored.
• Plan an evacuation route away from rivers or streams that may carry mud or debris flow.
• Keep a battery operated radio available at all times.
• If there is an eruption predicted, monitor the radio, TV or NOAA Weather Radio for evacuation information.
• Follow the advice given by the authorities.

After a volcanic eruption:

• Evacuate if advised to do so.
• Be prepared to stay indoors and avoid downwind areas if ashfall is predicted.
• Do not approach the eruption area.

• Be aware of stream and river channels when evacuating.
• Move toward higher ground if mudflows are approaching.

Be prepared for ashfall generated from volcanoes:

• Have dust masks available.
• Close doors, windows and dampers. Place damp towels at door thresholds and other draft sources.
• Put stoppers in tops of your drainpipes.
• Protect dust-sensitive electronics.
• Keep roofs free of ash in excess of 4 inches.
• Remove outdoor clothing before entering a building.
• Wash vegetables from the garden before eating.
• If ash is in the water, let it settle before drinking.
• Use a battery-operated radio to receive information.
• Keep children and pets indoors.
• Minimize travel — ash may be harmful to your vehicle.
• Frequently change oil and air filters in your automobile.
