MAP: Lahar (Volcanic Mudflow) Evacuation Routes

By on August 17, 2011. Posted in .

Helping Hand House has 72 units of housing spread throughout eastern Pierce County, giving us a significant interest in emergency management, particularly as it relates to Mt. Rainier. We are posting the following as a resource to our community in the Puyallup area, and was obtained from the City of Puyallup’s Emergency Management Department (Information about which can be obtained at:  http://www.cityofpuyallup.org/emergency-management/).

The following is a map (covering Puyallup city limits only) of the probable areas that would be covered in the event of a lahar (mudslide), potentially to the depth of up to 20 feet. Sumner would likely be buried to depths of 30 feet (Source: USGS). Please be aware of the evacuation routes as you consider your family’s emergency plans.

The trigger to listen for would be the lahar warning sirens to sound continuously, or the notifications that you would get through the emergency alerts on your cell phone if you have signed up for them (you need to sign up for both Pierce County AND Puyallup).
