Volcano Information

Anchorage is surrounded by a number of volcanoes that could erupt. Depending on prevailing winds, ash could be carried into Anchorage. In the past 20 years, Anchorage has experienced ash fall from eruptions of Mt. St. Augustine, Mt. Redoubt and Mt. Spurr.

Current conditons on volcanic eruptions can be found at: https://avo.alaska.edu/

For information on ways to avoid or minimize contact with volcanic ash please see below.

People exposed to airborne volcanic ash can experience various eye, nose and throat symptoms.   Although these symptoms can cause discomfort, short-term exposure to ash generally does not constitute a significant health hazard for most people.  Risk from exposure to ash is greatest for infants, children and those with asthma or chronic lung diseases such as emphysema.  Anyone in these risk groups should be particularly careful to avoid exposure. Contact your health provider if you are concerned about symptoms.

The Municipal Department of Health and Human Services advises everyone to avoid unnecessary exposure to ash and offers these suggestions:

• If possible, remain indoors during heavy ashfall periods.
• Wear a disposable face mask outdoors to reduce inhalation of ash particles. Dust masks can be purchased at most hardware stores. Dust masks with exhalation valves cause the least stress for users, keep the masks cooler, and help reduce fogging of safety glasses.
• NIOSH standard N95 Particle Respirator 3M Model 8511 with exhalation valve
• NIOSH standard N95 Particle Respirator 3M Model 8219 without exhalation valve
• A wet cloth or bandana placed over the mouth and nose can help reduce exposure when masks are not available.

Contact lens wearers are advised to switch to eye glasses to reduce eye irritation from ash exposure and wearing goggles can help to protect your eyes.  Wear long sleeved shirts and gloves.  Avoid bare skin contact with ash as much as possible.

The Municipal Department of Health and Human Services will be monitoring air quality throughout any existing episode.  Air quality updates can be obtained by calling 343-4899.
