More Steam And Ash Released Today

An eruption this morning at Mount St. Helens released more steam and ash into the air.  Today's eruption has been described as much larger than yesterday's.  U.S. Geological Survey scientists say we'll see more big releases as the volcano gears up for the main event.

They also say the big eruption will likely involve magma in addition to the steam and ash we've seen over the last few days.

More vents have opened inside the crater as the lava dome continues to grow.  These are signs to scientists the big eruption is coming, but they're still not expecting one as big as the eruption of 1980.
