If volcanic ash blows into Anchorage, here’s how to keep your meals safe and your family nourished.
When Mt. Spurr erupts—and it has before—volcanic ash can be carried by high-altitude winds straight into Southcentral Alaska. In fact, the last time Mt. Spurr erupted in 1992, it blanketed Anchorage in about an eighth of an inch of ash, forcing Ted Stevens Anchorage International Airport to shut down for 20 hours and disrupting life across the city.
If ashfall from Mt. Spurr reaches Anchorage again, your food and water supply could be impacted—even if you're nowhere near the volcano itself.
At Food Bank of Alaska, we want to help you prepare before the ash starts falling. This guide focuses on protecting your food, water, and overall nourishment—because even in an emergency, everyone deserves access to safe meals.
Ash from Mt. Spurr isn’t just dirt. It’s a gritty, abrasive mix of tiny rock, mineral, and glass particles that can:
Contaminate food and water supplies
Scratch skin and lungs
Damage crops and livestock
Interrupt electricity and water service
Even a light layer of ash can cause serious health concerns if ingested, especially for young children and older adults.
Prepare to be self-sufficient for at least 3 days, but ideally up to 7–10 days, in case stores close or roads are unsafe.
Doesn’t require cooking
Doesn’t need refrigeration
Requires minimal water to prepare
Canned soups, vegetables, beans, fruit
Dry pasta, rice, crackers, cereal
Nut butters, granola bars, jerky
Baby formula and shelf-stable baby food
Pet food and snacks
Manual can opener!
Ash can contaminate open water sources and potentially affect city water, depending on the severity.
Store at least one gallon of water per person per day
Follow boil water advisories from AWWU or Alaska DEC
Have backup methods for purifying water (boiling, filtration tablets, etc.)
Ash can easily find its way into your home—take steps to keep your kitchen safe:
Keep windows and doors closed
Cover vents and wipe down counters frequently
Wash your hands before handling any food
Store food in sealed containers
Use food from your refrigerator first, then freezer, then pantry if the power goes out
Volcanic ash doesn’t just affect the air—it can delay food from getting to your community.
Ashfall may ground cargo planes and delay barge shipments, disrupting supply chains across Alaska.
Grocery stores may see shortages or limited restocking in the days following an eruption.
Rural and remote communities that rely on air cargo could experience longer delays.
📦 Stock up now on shelf-stable foods, baby supplies, and pet food—especially if your household needs specific dietary items or lives off the road system. Preparing ahead means fewer worries later.
To keep our staff, volunteers, and community safe, Food Bank of Alaska will close during heavy ashfall events and suspend in-person services until conditions improve.
We’ll reopen as soon as it is safe to do so and will post regular updates on our website and social media.
Even when our doors are closed, we’re working behind the scenes to ensure a strong and swift response once it’s safe to resume operations.
