Mount St. Helens Alert Level Change
Past Alert Level: Volcano Alert (Alert Level 3)
New Alert Level: Volcano Advisory (Alert Level 2)
October 6, 2004 9:15 A.M., PDT
Following yesterday morning’s steam-and-ash eruption, seismicity dropped to a low level and has remained low. Low-level tremor observed following the eruption is also gradually declining. Lack of earthquake and rockfall signals suggest that deformation of the uplift area on the south side of the 1980-86 lava dome has slowed. Brief visual observations this morning from Coldwater Visitor Center showed weak steam emissions from the crater. We infer that the vigorous unrest of the past few days has lessened and that the probability of an imminent eruption that would endanger life and property is significantly less than at any time since Saturday, October 2, when the alert level was raised to Volcano Alert (Level 3). Therefore, we are lowering the alert level to Volcano Advisory (Alert Level 2).
Such decreases in the level of unrest, which may reflect a decrease in the rate of magma movement, have been common at Mount St. Helens during eruptions in 1980-86 and also at similar volcanoes elsewhere. Episodic changes in level of unrest over periods of days to weeks, or even months, are possible. We don’t think that the current episode of unrest is over and we expect fluctuations in the level of unrest to continue during coming days and months. Everyone should be aware that escalation in unrest and perhaps an eruption could occur suddenly or with very little warning. There may be little time to raise the Alert Level before a hazardous event occurs. Therefore, we continue to monitor the situation closely and will issue additional updates and changes in Alert Level as warranted.

Yeah I was starting to wander why the news had gone quiet on this subject yesterday.

Mount St. Helens Update, October 13, 2004, 7:00 a.m, PDT
Current status is Volcano Advisory (Alert Level 2); aviation color code ORANGE
Seismic activity remained at a low, but slightly increasing level overnight. Yesterday’s visual observations and thermal imaging of the 1980-86 lava dome, the intensely deforming and uplifting area on the south side of the dome, and the new lava extrusion first seen on October 11 were hampered by steam clouds. Conditions appeared similar to those of October 11, with high temperatures (up to 600 degrees C) around the fin-shaped lava extrusion in the western part of the uplift. The area of high temperature appears to have increased in size. Abundant steam continued to rise from the fin area to the crater rim, from which it was dispersed southeastward by strong winds.
A new instrument array was lowered onto the uplifting area on October 12 by helicopter. It contains telemetered seismic, GPS, and tilt instruments, as well as a microphone. It will provide critical information on rate of movement of the uplift as well as a close-in seismic station, which is proving useful in interpreting very small seismic events that do not appear at more distant stations. Today, field crews will take new thermal images of the crater floor and dome, make gas-sensing measurements, perform routine maintenance of GPS sites, and take hydrological measurements.
Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), combined with eruption models, show generally northerly winds. Any ash clouds will drift southward to southeastward.
As a result of the intense unrest of the past two and one-half weeks and recent observations, we infer that magma is at a very shallow level and is extruding onto the surface. Incandescence from hot rock or gases reflects off steam clouds and is visible from north of the volcano. During times of unrest, Mount St. Helens and similar volcanoes elsewhere typically go through episodic changes in level of unrest over periods of days to weeks, or even months. Such changes are in part driven by variations in the rate of magma movement. We expect fluctuations in the level of unrest to continue during coming days. Escalation in the degree of unrest could occur suddenly or with very little warning. There may be little time to raise the alert level before a hazardous event occurs. Therefore, we continue to monitor the situation closely and will issue additional updates and changes in alert level as warranted.
Today’s media briefing will be held at the Headquarters of the Gifford Pinchot National Forest at 10:30 a.m.

Could you imagine if your missus took so long to blow 
Excellent photographs and images. I find the whole subject of seismic activity fascinating (blimey that makes me sound boring).
A magnificent sight if Mt St Helens does blow but the consequences for those living locally are enormous. As someone said above, however, its Mother Nature showing us that she is still in charge!!

King 5 TV in Seattle reported a guy last week who decided to see for himself how close the eruption was. He climbed to the top of the crater and peered over - all the time taking a video of the experience.
Needless to say the forest rangers etc were unimpressed and warned others to stay away, stating that they could be arrested if caught. I wonder if there are police at the top ready to move in if necessary?
