LANDSLIDEAre You Ready for An Eruption?MOUNT RAINIER IS AN ACTIVE VOLCANO

Mount Rainier is much more than a mountain in the sky. Constructed of hundreds of lava flows, and capped by as much glacier ice as all other Cascade volcanoes combined, Rainier’s steep rubbly slopes and abundant water make it prone to landslides and lahars (volcanic mudflows), especially during eruptions. Lahars are the biggest hazards to the area. Scientists and emergency officials watch and warn. Do your part by being prepared.

• Look at the map. Assess the hazards where you live, work, and commute.• Make a plan. Identify lahar evacuation routes and shelter above valley floors.• Assemble emergency supplies and a plan to reunite. • Share your plans with family, neighbors and friends.
