There are about 500 volcanoes around the world which have erupted in
recorded history and may erupt in the near future. They are called active
volcanoes. ① Many of them are located in the Pacific, such as in Japan and
Hawaii. ② Under the Pacific Ocean, the earth's plates are moving slowly and
colliding, which sometimes causes eruptions. However, not all volcanoes are
active. Before a volcano erupts, magma begins to slowly rise from cracks
near the surface. Some volcanoes are temporarily inactive and some are
"extinct," meaning they will never erupt again.
