2015 marks the centennial of the May 22, 1915 explosive eruption of Lassen Peak. The eruption forever altered an already dynamic landscape and led to the creation of a national park which serves as a place of discovery for curious visitors and a living laboratory for a variety of scientists.
USGS California Volcano Observatory and Lassen Volcanic National Park have teamed up to celebrate the eruption anniversary with several events to be held at the park over the Memorial Day weekend. Centennial resources and a schedule of events can be found on our 1915 eruption resource page.
