Volcano

Contact Information

Washington is home to five active volcanoes, which can pose a variety of risks to the communities around them. Renton will likely not be directly impacted by lava or pyroclastic flows or lahars, but could still face disruption from a volcanic ash release.

During a Volcanic Eruption

Although Renton is not directly at risk of lava flows, pyroclastic flows, or lahars, take care to avoid volcanoes that are displaying signs that an eruption is imminent. Follow any evacuation orders given by local officials if you are near a volcano when eruption is imminent. Falling ash from a volcanic eruption may have significant impacts in Renton.

Protection from Falling Ash

  • Remain indoors with doors, windows, and ventilation systems closed until the ash settles.
  • If you have a respiratory ailment, avoid all contact with any amount of ash. Stay indoors until local health officials advise it is safe to go outside.
  • Monitor local news stations and a NOAA Weather Radio for the latest emergency information.
  • Wear long sleeved shirts and long pants.
  • If you wear contact lenses, use glasses or wear goggles.
  • Use a dust mask or a damp cloth over your face if you must be in contact with ash.
  • Clear heavy ash from flat or low-pitched roofs and rain gutters. Ash can accumulate and pose a threat of roof collapse.
  • Avoid driving or running vehicle engines. Driving can stir up ash that can clog engines, and damage and stall vehicles. If you must drive, keep speed at or below 35 MPH.
