Earthquake activity has increased at Mt. St. Helens, but overcast skies has hampered scientists’ ability to see what was happening at the volcano.
Quake activity had been low, indicating that molten rock is moving upward with little resistance. By Saturday, however, quakes of magnitude 2.4 were occurring every minute or two.
Clouds lifted a little at dawn Saturday to reveal the mountain covered with snow, but continued to lessen visibility.
