Multiple outbursts on Mount St Helens last night

The level of activity on Mount St Helens increased this morning, with two separate outbursts occurring at 02:13 and 04:08 (local time).

The second event resulted in at least two distinct glows following the outburst, something we haven't seen on the mountain for months. The two glows appeared to be on opposite sides of the lavadome, which may mean further fracturing and landslides from the ridge of the dome.

New movies of the events have been posted and a picture of the dual glows visible in the crater is shown below.
