Volcanoes tend to have seismicity that waxes and wanes over time. That’s considered normal and not necessarily a cause for concern. Let’s check on Mount Adams to see what USGS scientists are doing to learn more about its recent earthquake activity and what it could mean for this Cascade Range volcano.

Large lahars (volcanic mudflows) pose substantial threats to people and property downstream from Mount Rainier, Washington. Lahars can occur during an eruption, as happened at Mount St. Helens on May 18, 1980. Lahars can also begin as large landslides that occur without warning, traveling down river channels to densely populated areas downstream.

USGS geologist Dan Dzurisin is near Sisters, in Central Oregon, to set up portable GPS monitoring equipment to track something that's been going on for 25 years and still goes on today. It’s uplift, a subtle rise in the ground’s surface, in an area west of South Sister volcano.
