RECENT OBSERVATIONS: The crater area continues to remain seismically very quiet. Late-season storms continue to pile up snow and no field work is planned for the near future. Radar imagery aquired by personnel from the Jet Propulsion Laboratory earlier in the week shows that the east and west arms of Crater Glacier are now touching or almost touching just north of the 1980s lava dome. Thus the old and new lava domes in the crater are now encircled by ice.
RECENT OBSERVATIONS: The crater area has been seismically quiet this week. No additional field work was carried out.
RECENT OBSERVATIONS: There was no field work done at Mount St. Helens this week. There was no significant seismicity, with only four very small earthquakes located near the volcano by the Pacific Northwest Seismic Network. There were no tilt changes associated with this activity.
RECENT OBSERVATIONS: There was no field work done at Mount St. Helens this week. The most significant development was a small, magnitude-2.0 earthquake on Tuesday at 11:31 PST, and very small earthquake swarm on Thursday, starting with a roughly magnitude 1.2 event at 2:16 PM PST and followed by several smaller events over a seven-minute period. There were no tilt changes assocaited with this swarm.
