In October 2004, almost 25 years after Mount St. Helens blew 1,300 feet off its top, the volcano again erupted. It was a small eruption compared to the cataclysmic blow of 1980, but it made clear that the mountain was coming back to life. But Mount St. Helens isn’t the only volcano in the Northwest showing signs of life. Just outside of Bend, the land beneath the South Sister is being pushed up by mysterious volcanic forces miles beneath a popular hiking trail. OREGON FIELD GUIDE presents a half-hour special that explores new insights and uncovers new volcanic mysteries. Tune in to the stations of Oregon Public Broadcasting television on Thursday, January 13 at 8:30pm to learn more about what’s happening in the “Volcanoes in Our Backyard.”

Mount St. Helens erupted with almost no warning in 1980. Had the technology we have today been available then, scientists may have been able to detect the swelling of the earth and accumulation of lava prior to the explosion. That technology is now being used to measure the swelling of the ground in the newly awakened volcanic zone near Bend. Rising at the rate of about one-and-a-half inches a year, some scientists think this could portend more volcanic activity. Are the Cascades entering a new era of eruptions? OREGON FIELD GUIDE follows scientists as they search for clues that may help them predict the next Cascade eruption.
