Mount St. Helens Volcano Activity

Seismic activity remained at a low, but slightly increasing level overnight.
Conditions appeared similar to those of October 11, with high temperatures (up to 1100 degrees F) around the fin-shaped lava extrusion (slab) 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 is dispersed southeastward by strong winds.
The thermal camera recorded temperatures approaching 1292 degrees F in an area adjacent to the slab; approximately the same location as the source of a small ash explosion observed from the air on October 11. The slab itself remained above 752 degrees F. News footage taken during the early evening yesterday captured dramatic incandescence or glowing rock that reflects these high temperatures measured with our thermal cameras.
A new instrument station called a BLIS 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 which 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. GPS measurements continue to show no significant movement of the north side for the 1980-86 lava dome or the outer flanks of the volcano. There is no evidence that the south flank of the mountain is deforming in any way.
Additional visual and thermal observations will be made today to further evaluate this interpretation. We will also be conducting a gas measuring flight to evaluate the rate of emission of carbon dioxide, hydrogen sulfide, and sulfur dioxide. Ash samples collected from explosions during the past week are being analyzed. Field crews will be conduction routine maintenance of GPS sites and making hydrologic measurements on stream flows and stream temperatures
The intense unrest the past two and one-half weeks combined with yesterday’s observations, the USGS is now interpreting the current activity as a dome-building event. Dome growth is a dynamic process and as was observed in the mid 1980’s, 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. USGS expects fluctuations in the level of unrest to continue during the coming days.

Wind forecasts from the National Oceanic and Atmospheric Administration (NOAA), combined with eruption models, show generally northerly winds. Any ash clouds will drift south to southeastwardly.
