Prepare for two different instructions: evacuate when officials order you out, or shelter from ash when authorities say staying indoors is appropriate. Those choices depend on your volcano, hazard zone, wind, roads and local orders, so start with your local emergency-management agency and volcano observatory rather than a generic national map. The CDC’s core advice is simple: “Follow the advice of local officials for information on preparing for a volcanic eruption.”
Use the checklist below to build both plans, equip every household member, set up reliable alerts and act without delaying an evacuation. Keep in mind that an eruption can create different hazards in different places, and a shelter instruction can change into an evacuation order.
Start with local information, not a generic checklist
Volcanic hazards differ by volcano and can include ashfall, falling rock, lava, mudflows and other threats. No national checklist can tell you whether your address is in a hazard zone, which road will remain open or which shelter will accept your family and pets. Identify those details before an alert.

| Information to find | Why it matters | Where to verify |
|---|---|---|
| Your hazard zone and expected hazards | Determines whether an evacuation or shelter order may apply to your address. | Your local emergency-management agency and the relevant volcano observatory. |
| Official evacuation routes and assembly points | Routes may be designated because ordinary roads can be blocked or unsafe. | Local emergency-management maps and current official instructions. |
| Approved shelters and their rules | Some shelters cannot accept animals or may have accessibility limits. | Your local authority, shelter operator and county or municipal website. |
| Alert channels and backup methods | You need updates if power, mobile service or a preferred app fails. | Local alert registration, official radio announcements and the volcano observatory. |
Ask local officials which alert wording means “prepare,” which means “be ready to leave,” and which means “leave now.” Record the current route, the nearest assembly point and any zone boundaries that affect your address. Bookmark official pages, write down essential phone numbers and keep a paper copy of the route and shelter information in your emergency kit. Conditions can change quickly; treat a new order from authorities as the controlling instruction.

Make two household plans
Plan A: evacuation
Decide where everyone will meet if separated, who can collect children or dependants, and where the household will go if your usual destination is inside the affected area. Choose a destination that will accept every person and, if possible, your pets. Identify more than one way to get there, but use only a route that officials designate as open when an evacuation begins.
List people who may need help with walking, hearing, vision, communication, medication or transport. Assign a specific helper and a backup. Include neighbours, relatives, schools, workplaces and caregivers in the communication plan when they are responsible for a household member. If a family member is away when the order arrives, agree in advance whether that person goes directly to the meeting place or follows the official evacuation instruction from their current location; do not create a plan that depends on crossing a closed zone.
Plan B: sheltering from ash
Choose an above-ground interior room without windows where everyone can gather. Store a working radio, water, food, medicines, lights and protective equipment close enough to reach without going outdoors. Decide who will close windows, turn off systems and bring pets inside. Sheltering is appropriate only when authorities say it is; officials may later order evacuation of the areas at greatest risk.
Identify the room’s doors, windows, ventilation openings and fireplace damper before an emergency. Make sure household members know which heating, air-conditioning and fan controls must be turned off. Keep the room usable for someone who needs mobility equipment, a communication aid or temperature-sensitive medication, and plan how that person will get there without repeated trips outside.
Practice the communication plan
Teach every household member how to receive an official alert, call or message the designated contact and report the household’s meeting place. Practice when mobile networks are available and when they are not. Keep a written contact card for children and anyone who may not remember phone numbers under stress. Do not rely on a single phone, app or internet connection.
Use a simple check-in message so relatives know whether you have evacuated, where you are going and whether anyone needs help. Assign one person to monitor official updates while another gathers people and supplies. Practice both a rapid departure and a move to the shelter room; a plan that has never been rehearsed is easy to misremember under pressure.

Assemble supplies before an alert
CDC’s volcanic-eruption list includes the items below. Build the kit around your actual household rather than buying a generic package whose contents you have not checked.
Recommended Free Tools
| Supply | How to prepare it |
|---|---|
| Flashlight and extra batteries | Keep spare batteries with the light and test both periodically. |
| First-aid kit and manual | Include the kit’s instructions and replace used or expired items. |
| Emergency food and water | Choose items household members can eat and drink, including any medical or cultural requirements. |
| Manual can opener | Store it with canned emergency food; an electric opener may be unusable during a power failure. |
| Essential medicines | Maintain an accessible supply and a current medication list. For an evacuation, CDC advises taking at least a one-week supply of prescription medicines. |
| Sturdy shoes | Keep footwear where it can be put on before walking through debris or ash. |
| Respiratory protection | Use the ash-protection guidance below to select and wear an appropriate respirator. |
| Goggles | Protect eyes from airborne ash; keep them with the respirator and other protective equipment. |
| Battery-powered radio | Store spare batteries and learn which local station carries emergency information. |
Add household-specific items
- Prescription and over-the-counter medicines, copies of prescriptions, glasses, hearing-aid supplies and other daily medical equipment.
- Food, water, carriers, leashes and medications for each pet or service animal.
- Items for infants, older adults and people with disabilities or sensory needs.
- Chargers, power banks and paper contact information, while remembering that electronic devices may lose power or service.
- Important documents and keys that can be taken quickly without searching through the home.
Keep the kit in a known, reachable location. Check batteries, food, water, medicines, prescriptions and pet supplies on a schedule you can maintain. Store a small version in each vehicle if evacuation may begin away from home. Keep sturdy shoes and protective equipment where they can be put on immediately, not buried in a high cupboard or locked vehicle.
Set up alerts you can actually receive
For volcanoes monitored in the United States, the USGS Volcano Notification Service (VNS) provides free email notices that can be customized by volcano and notice type. The service does not send text messages directly. Some mobile carriers offer email-to-text gateways, but delivery performance varies, so treat that method as a supplement rather than a guarantee.
Register for your local government’s emergency alerts as well as observatory notices. Keep a battery-powered radio available for power or internet outages, and verify the radio’s batteries before an emergency. Follow the relevant observatory and local authority for changes to alert levels, routes and shelter instructions. Check that alert emails are not being filtered into spam and that more than one adult can access the account.
When officials order an evacuation
Do not wait for ash to reach your home or for every family member to return before leaving. A voluntary warning, mandatory order and route closure can have different meanings locally; follow the wording and deadline in the current official message.
- Confirm the order and your route. Read or listen to the complete official instruction. Use the designated evacuation route and expect congestion or delays. Do not assume a familiar shortcut or alternate road is open.
- Take people, medicines and essential supplies first. Collect household members, identification, the emergency kit, protective equipment and at least a one-week supply of prescription medicines when it is available and safe to collect.
- Take pets where possible. Bring carriers, leashes, food, water and medicines. Because many emergency shelters cannot accept animals, use the pet-friendly destination you identified during planning or follow official instructions for animal sheltering.
- Arrange transportation. Fill the vehicle’s fuel tank if doing so is safe. If no vehicle is available, use the ride arranged with friends or family, or follow official transport directions. Tell the transport provider about mobility, medical and animal needs.
- Shut off utilities only if there is time and it will not delay departure. CDC says that, if time permits, you can turn off gas, electricity and water and disconnect appliances. Never re-enter or stay behind to complete this step when authorities are telling you to leave.
- Drive for the conditions. FEMA warns that heavy ash can clog engines and stall vehicles. Avoid driving in heavy ash; if officials direct you to travel, proceed on the designated route and follow their safety instructions.
- Report your status through the agreed contact. A short message to the household contact can prevent repeated calls, but do not delay departure to send updates.
Keep the vehicle’s doors and windows closed if ash is falling, and do not stop on a route to collect belongings. If you are already outside the evacuation area, do not return for belongings unless officials explicitly authorize it. Roads and zones can change after the first order.

When authorities direct you to shelter from ash
Sheltering from ash is a deliberate, temporary action—not proof that every indoor location is safe. Keep monitoring official instructions in case conditions require evacuation.
- Bring everyone and pets indoors. Take food, water, medicines, goggles, respiratory protection, a flashlight and the battery radio into the selected room.
- Close and lock exterior doors and windows. FEMA also advises covering ventilation openings and sealing doors and windows when taking temporary shelter from ash. Follow local guidance for the appropriate way to cover or seal them.
- Turn off systems that draw outdoor air. CDC advises turning off heating and air-conditioning systems and fans. Close the fireplace damper.
- Use the interior room. Stay in an above-ground room without windows. Keep the radio working and listen for updates rather than opening doors repeatedly to check outside.
- Limit entry and exit. Each opening can allow ash inside. Coordinate trips so one person is not repeatedly exposed while others remain unprotected.
- Follow every new instruction. Officials may change the shelter recommendation, identify a different zone or order evacuation. The latest official message takes priority over your original plan.
If ash enters the building, keep unnecessary people away from the affected area. Do not begin extensive cleanup while an official shelter order is active unless authorities provide instructions. A roof can carry dangerous extra weight, and ash-covered surfaces may be slippery; FEMA cautions against getting on a roof to remove ash without appropriate guidance or training.
Protect lungs and eyes from volcanic ash
Volcanic ash can harm health, particularly the respiratory tract, and it can irritate eyes. The CDC recommends a NIOSH-approved N95 respirator when you are outdoors or cleaning ash that has entered indoors. “NIOSH-approved” is the key category, not a brand name. Follow the respirator’s own directions for putting it on, achieving a seal and replacing it. Fit matters; facial hair, improper positioning or a damaged respirator can reduce protection. A respirator does not make every outdoor condition safe, so avoid exposure and follow evacuation or shelter orders.

Keep goggles available and use them as directed. Do not assume one model or size fits every person; check the manufacturer’s directions and arrange alternatives in advance for anyone who cannot obtain a proper fit. Children, older adults and people with breathing or heart conditions may be more vulnerable; ask a clinician in advance how they should manage respiratory protection and medicines.
If ash has entered a building, limit the number of people cleaning it and use the recommended respirator and goggles. Follow the product directions rather than wearing a damaged, wet or poorly fitting respirator. Do not improvise roof-cleaning operations: FEMA cautions against getting on a roof to remove ash without appropriate guidance or training. Heavy ash can add weight and make surfaces slippery, creating risks beyond inhalation.
Plan for pets and people who need extra assistance
Pets and service animals
Include animals in both plans, not as an afterthought. Keep carriers, leashes, identification, food, water and medicines ready. Confirm which relatives, hotels, boarding facilities or shelters can accept animals because many emergency shelters cannot. Service animals should remain with their handlers, and their food and medical needs belong in the same grab-and-go plan. Ask the shelter or transport provider about species, crate and documentation rules before an alert.

Medication and medical equipment
Keep an up-to-date list of medicines, doses, prescribers and allergies with the kit. Store essential equipment where it can be collected quickly, and identify backup power or transport needs. During a possible evacuation, CDC’s guidance is to take at least a one-week prescription supply; request refills before an alert if your clinician and pharmacy allow it. Include spare glasses, hearing-aid supplies and instructions for equipment that another caregiver may need to operate.

Use plain, practiced instructions and assign an adult to each person who needs assistance. Plan for mobility devices, communication aids, sensory needs and supervision if household members are separated. Tell schools, workplaces, caregivers and transport providers which official contact and meeting place the household uses. Keep a paper card explaining communication or medical needs for a person who may not be able to describe them during a hurried evacuation.

| Mistake | Safer alternative |
|---|---|
| Assuming every eruption has the same hazard or that staying home is always safe. | Use the local hazard map and obey the current order from authorities and the volcano observatory. |
| Waiting for a personal warning before leaving. | Register for local alerts, VNS where applicable and radio updates; act when the official order arrives. |
| Taking an unverified shortcut. | Use the designated route, even when it is slower, because other roads may be blocked. |
| Driving through heavy ash. | Avoid heavy ash; it can clog engines and stall vehicles. |
| Using a nuisance dust mask as if it were an N95. | Use a NIOSH-approved N95 as directed when outdoors or cleaning indoor ash; treat a dust mask only as a less-protective last resort. |
| Leaving pets out of the evacuation plan. | Confirm pet-friendly destinations and carry food, water, carriers, leashes and medicines. |
| Climbing onto a roof to clear ash without training. | Wait for authoritative guidance and qualified help; roof work can be dangerous. |
| Relying on a single digital alert. | Combine local alerts, observatory notices, a battery radio and a written communication plan. |
| Delaying departure to shut off utilities or collect possessions. | Leave when directed; turn off gas, electricity and water only if it is quick and safe. |
| Assuming a shelter accepts every household member. | Confirm animal, accessibility and transport rules before an emergency. |
Keep the plan usable
Review the plan whenever your address, household, school, workplace, pets, medicines, vehicle or local route changes. Replace expired supplies, test radios and flashlights, update contacts and verify that the selected shelter still accepts your household. Practice both a rapid departure and a move to the interior shelter room so nobody has to invent steps during an alert.
For detailed official guidance, read the CDC’s Preparing for a Volcanic Eruption page, check the USGS Volcano Notification Service for U.S.-monitored volcanoes and consult FEMA/Ready.gov’s volcano hazard information sheet. The CDC page was published May 15, 2024, and updated and reviewed August 25, 2026; local instructions remain more specific than any national guidance.
Frequently Asked Questions
Should I evacuate or stay inside during an eruption?
Follow the current instruction from local authorities and the relevant volcano observatory. Evacuate by the designated route when ordered. Shelter from ash only when authorities say staying indoors is appropriate, and keep monitoring for a later evacuation order.
Is a regular dust mask enough for volcanic ash?
No. CDC recommends a NIOSH-approved N95 respirator when outdoors or cleaning ash that has entered indoors. A nuisance dust mask offers less protection and is only a last resort, not an equivalent substitute. Follow the respirator’s directions and ensure it fits properly.

Can I take my pet to an emergency shelter?
Many emergency shelters cannot accept animals. Plan a pet-friendly destination, relative, hotel or boarding option in advance, and keep carriers, leashes, food, water, identification and medicines ready. Follow local instructions for service animals and animal shelters.
Does USGS Volcano Notification Service send text alerts?
VNS provides free, customizable email notices for U.S.-monitored volcanoes but does not send text messages directly. Carrier email-to-text gateways may work inconsistently, so use them only as a supplement to local alerts, observatory updates and a battery-powered radio.
How much medication should I take if evacuation is possible?
CDC advises taking at least a one-week supply of prescription medicines for an evacuation, when it is available and safe to collect. Keep a current medication list, prescriptions, glasses, hearing-aid supplies and essential medical equipment with the kit.
