Mount St. Helens

Dome building slows at Mount St. Helens

Mount St. Helens appears to be calming down. Scientists keeping close watch over the Washington state volcano report the new lava dome inside is not growing as rapidly as it had been in October. An explosion early last week destroyed a camera and some measuring equipment that had been placed in the crater. Scientists say they want to put new equipment in place, but are waiting to see whether there will be another blast. Since December, Mount St. Helens' lava dome has been growing in height by about 33 feet a day. Scientists are concerned a collapse could unleash a cloud of ash that could cause problems for aircraft. A massive eruption in May 1980 blew the top off the mountain and killed 57 people.
