Are you ready for an eruption? Mount Baker dominates the skyline of northwestern Washington and southwestern British Columbia. Glacier Peak is mostly hidden from view. Both volcanoes have erupted in recent centuries and will erupt again, disrupting the landscape and the lives of people downstream and downwind. Learn what to do and where to get information.

Before and after satellite images of Leilani Estates subdivision
Before and after satellite images of Leilani Estates subdivisionThis comparison shows satellite images of Leilani Estates subdivision before and after the May-August 2018 eruption. The image on the right, collected in early September 2018, shows that the eastern portion of the subdivision has been covered by lava. The Fissure 8 lava channel runs northeast, with the Fissure 8 cone at the start of the channel.

Seismic array deployed to better understand magma transport during Kīlauea'
Seismic array deployed to better understand magma transport during Kīlauea'University of Utah seismologists install a nodal geophone on Kīlauea's lower East Rift Zone in June 2018. This instrument was part of a network of 82 seismometers deployed temporarily this summer to help scientists study the magma transport system beneath the volcano's eruption sites. USGS photo by B. Shiro.

GPS monitoring station P709
GPS monitoring station P709 is located on The Promontory between the South Arm and Southeast Arm of Yellowstone Lake. It was installed in 2005 as part of the Yellowstone component of the National Science Foundation's Plate Boundary Observatory (PBO) under permit YELL-SCI-5546.
