US government scientists have raised the alert level for Mt St Helens in Washington state after its second steam eruption in two days was followed by a powerful tremor.
The volcano alert of Mt St Helens was raised to level three, which 'indicates we feel an eruption is imminent, or is in progress', said US Geological Survey geologist Tom Pierson.
After lying dormant for many years, Mt St Helens
awoke again on October 4, 2004, spewing ash into the air.
