• Volcano is a mountain with a hole called a crater
  in the top. Sometimes lava and gases are thrown
  from the crater. This is a volcanic eruption.
  Eruptions can be quiet or explosive.

• Lava flows and destroys everything on the way.
  But it moves slowly and people can run away.

• Volcanic eruptions can be accompanied by other
  natural disasters, including earthquakes, rock
  falls and landslides, acid rain, fire, and
  tsunamis.

• Active volcanoes in the United States are found
  mainly in Hawaii, Alaska, and the Pacific
  Northwest. Active volcanoes of the Cascade
  Mountain Range in California, Oregon, and
  Washington have created problems recently. The
  dangerous area around a volcano covers
  approximately a 20-mile radius. Some danger may
  exist 100 miles or more from a volcano.
