Every day the earth is struck by dozens of earthquakes, but only a few are felt by the
population….
Though most volcanoes are dormant, there are currently more than 1 500 potentially active
volcanoes on earth.
Among these, some of the most visited are in Italy, Indonesia, Japan, Hawaii and
Tanzania.
According to many scientists, landslides are increasingly common and threaten such famous
monuments as Machu Picchu in Peru
or the Valley of the Kings in Egypt.
