family should create an escape plan. Those includes and alert procedure, hospital and medical services for treatment, identification will be needed for out of area transport or driving. You also will need a means of transport, communication with family and friends, public warnings should be reviewed, a place for shelter if needed, and a type of rescue if trapped or hurt.
For your escape you will need to be aware of mudflows, landslides, acid rain, tsunamis, and earth quakes. It’s recommended to avoid rivers and low areas. Always wear long-sleeved shirts and long pants when warned about a volcanic eruption. Use goggles or eyeglasses to help protect you eyes from debris. Avoid running a car or truck engines if ash fall and driving during ash fall because of ruining you vehicle.
