Rock Slab Growing at Mt. St. Helens Volcano


Explanation:
A new rock slab is growing at more than one meter a day on the
Mt. St. Helens volcano in
Washington,
USA.


The rock slab, growing since last November, now extends about 100 meters out from one of the volcano's craters.

A recently made time lapse movie shows the
rock slab growing.

Pictured
above, a
helicopter examines the
steaming hot rock slab late last month.

Mt. St. Helens underwent a
spectacular eruption in 1980 but has been undergoing a
comparatively serene eruption since 2004 September.

A new volcanic dome has been building which is now about 100 meters above the 1980s dome.

The rock slab is visible from the Johnson Ridge Observatory on the
erupting volcano.
