How old are volcanoes ?

• Volcanoes have been on earth since the dinosaurs
  but we really dont know how old they are because
  since the creation of the known universe they
  have been here erupting and preserving things
  from long forgotten civilisations.

SUPER VOLCANOES

• Super volcanoes
• A super volcano is the one of the most
  destructive forces on this planet. Only a few
  exist in the world and when they erupt they do so
  with a force thousands of times greater than
  other eruptions. They even threaten the survival
  of mankind. The long-term effects would be even
  more devastating. The thousands of cubic
  kilometres of ash that would shoot into the
  atmosphere could block out light from the sun,
  making global temperatures plummet. This is
  called a nuclear winter. A super volcano eruption
  could truly be an extinction level event. There
  is no way to stop it, no where to run and no
  where to hide.

• The "steam rings" are about 200m across
• By BBC News Online science editor Dr David
  Whitehouse
• Volcanologists have witnessed dramatic rings of
  steam and gas being blown out of volcanic vents
  on the side of mighty Mount Etna in Sicily.
• Etna is the tallest and most active volcano in
  Europe, situated where the European and African
  geological plates are colliding.

• Such rings have never been seen in such detail
  beforeDr Jug Alean and Dr Marco Fulle have been
  investigating Etna's growing level of activity
  and in February they saw the ejection of several
  spectacular hoops from the Bocca Nuova region of
  the mountain.

conclusion

• Volcanoes are very dangerous and should be
  approached with extreme caution and are very
  wondrous things that we still dnt know a lot
  about.
