Volcano Information

On this page we will give you important volcano information that explains what a volcano is and what to do before during and after a volcanic eruption.

A volcano is an opening or vent in the earth's crust from which molten rock debris, hot gases and ashes are emitted. Volcanic mountains are not like regular mountains. Regular mountains are pushed up from below, where as volcanic mountains are a built up accumulation of their own eruptive materials.

Some volcano eruptions can be relatively quiet or can be very explosive. Pressure from gases within the magma chamber deep in the earth's crust becomes so great that an eruption can occur. Magma that has erupted is called Lava. Lava which can be upwards of 2000 degrees and containing poisonous gases and ash may flow and destroy everything in it's path.

Volcanic ash from an eruption is made of pulverized rock which is very acidic, gritty, abrasive and odorous. Because of it's acid nature, volcanic ash can be very dangerous to breath in and can cause lung damage. Volcanic ash can also cause damage to engines, machinery and electrical equipment. When ash accumulates on a roof top it can cause the roof to collapse. The affects of volcanic ash can be felt as much as 100 miles or more away.

Natural disasters that can accompany a volcanic eruption are earthquakes, flash floods, mudflows, rock falls, landslides, fire, acid rain and under certain conditions, tsunamis.

Lateral blasts are sideways directed volcanic eruptions that can shoot large boulders and rocks at extremely high speeds for miles. Entire forests have been know to be knocked down due to this type of volcanic eruption.

• Be ready to evacuate immediately.
  
  
• If you live near a active or known volcano, have a family emergency kit on hand with googles and disposable breathing masks for all family members.
  
  
• Avoid active volcanos.

• All evacuation orders issued by authorities should be followed.
  
  
• Immediately evacuate the volcanic area to avoid any volcanic hazards.
  
  
• Stay away from river valleys and low-lying areas.
  
  
• Mudflows can occur near stream channels with heavy rain, do not try to outrun a mudflow, they can move more quickly than you realize. Do not cross a bridge if you see a mudflow approaching.
  
  
• Remember to help your neighbors, especially the ones with special needs.

• For the latest emergency information, listen to a battery-powered radio or television.
  
  
• To help with breathing, use a disposable breathing mask or a damp cloth.
  
  
• To cover your skin, wear long pants and long-sleeve shirts.
  
  
• Wear a pair of googles to protect your eyes.
  
  
• Use your eyeglasses, and do not use contact lenses.
  
  
• Areas downwind from the volcanic ash should be avoided.
  
  
• Keep indoors until the ash has settled. However, be aware that there can be a danger of a roof collapse.
  
• Windows, doors and all ventilation systems should be closed. This includes, chimney vents, air conditioners, fans and other vents.
  
  
• If there is an accumulation of ash on your roof, clear it off.
  
  
• Do not run vehicle engines while ash is present, this can clog engines and cause damage.
  
  
• It is not recommended to drive during heavy ash fall.

Safety is your first priority as are your physical and mental well-being. Recovering from an emergency situation is usually a gradual process that takes time and patience. If you need assistance, knowing how to get it makes the recovery process go faster and can be less stressful.

Make sure your property is safe to enter. For more volcano information, follow instructions from your local authorities and stay safe
