Mount Baker, Washington simplified hazards map showing potential impact area for ground-based hazards during a volcanic event.

Mount Baker in the background of the Tesoro oil refinery in Padilla Bay, Washington. Volcanic hazards from Mount Baker such as ash fall could impact this refinery during a future eruption.

At Mount Baker, Washington, observers noted continuing landslide activity in the upper Middle Fork Nooksack drainage that resulted in small debris flows and muddy floods. Scientists from multiple agencies and institutions coordinated observations, surveying, and sampling to gain an understanding of the situation.

The National Oceanic and Atmospheric Administration Ship Rainier is backdropped by Mount Baker, an active Cascade Range stratovolcano, in Washington. In September 2019, the Rainier conducted a bathymetric survey along Hawai‘i Island's Puna coast, where lava entered the ocean during Kīlauea Volcano's 2018 eruption.
