Hi Randall. Here is the reply from William Steele. I think this should show why most people in the USGS are reluctant to say anything to people about what might occur. There will always be someone who distorts what was said. Take Care…Don in creepy town Greetings Don, There is no alert for the Sisters volcanic area. There was some very bad reporting concerning a very small Ml .8 earthquake (< mag.1) that occured near S. Sister. 02/12/17 14:25:58 44.04N 121.85W 10.3 0.8 AD For a good overview see our Three Sisters page at: http://www.ess.washington.edu/SEIS/PNSN/SISTERS/welcome.html Check out the recent earthquakes area and you will find we have only about 3 small events a year in this area. Nothing to be concerned about. Willie Scott of the Cascade Volcano Observatory gave an interview to a Bend newspaper reporter who hiped up the story implying that this tiny event might be a precursor to an eruption. No worries.

I thought the rest of you/us would like to see what tiny weenie things can do in the eastern Oregon press. What would they say if there were (heaven forbid) 2 earthquakes in a year. The fact that about anywhere in the world will have this level of seismic activity seems to be lost on reporters with no news to report.

This is not the story that I expected to be written by a Bend Bulletin reporter with whom I spoke yesterday! It went out on the AP and several Portland TV stations have called. Unbelievable. Hopefully the interest won't go beyond the two TV stations with whom I will speak and hopefully counter the incredibly irresponsible tone (or am I too sensitive) of the article.

Second minor quake could precede eruption bengfwam BEND, Ore. (AP) -- Seismic recorders detected a tiny earthquake this week near the South Sister, an indication that a bulge on the volcano's west flank could be closer to eruption. The quake barely registered at magnitude 0.8 -- but it could be part of a series of low-powered quakes that precede an eruption, said Willie Scott, a volcanologist at the U.S. Geological Survey Cascades Volcano Observatory in Vancouver, Wash. "Could this be the first of many quakes?" Scott said. "Who knows? In places like this that were getting ready to approach eruption, we could be measuring hundreds or thousands of small earthquakes." Scott said a seismic monitoring station near a peak called The Husband picked up the tremor at about 6:25 a.m. Tuesday. Scientists pay close attention to the South Sister's 10-mile bulge, which was first detected in 1996 and has since grown an inch a year. Officials believe the bulge formed because a chamber of magma deep beneath the earth's surface is growing. "The thought is that the crust is being bent and bent, and sooner or later, it will start fracturing. Sooner or later, we will see swarms of small earthquakes," Scott said. Other volcanoes in the Cascade Range, such as Mount St. Helens, Mount Rainier and Mount Hood, all experience more earthquakes -- but they don't have a bulge, Scott said. South Sister, the youngest of the Three Sisters, erupted twice about 2,000 years ago. (Copyright 2002 by The Associated Press. All Rights Reserved.) APTV 12-18-02 1044PST
