Cascadia Earthquake Preparedness for Aging Adults in the Portland Metro Area
A major earthquake can disrupt transportation, electricity, water service, phone networks, and access to healthcare. For older adults who live alone, use mobility equipment, or rely on daily assistance, these disruptions can create additional challenges.
The Cascadia Subduction Zone lies offshore of the Pacific Northwest and has the potential to produce a very large earthquake. Although no one can predict the exact timing of a future earthquake, Oregon emergency officials encourage residents to prepare for prolonged disruptions following a major disaster.
For families in Beaverton, Portland, Washington County, Multnomah County, and Clackamas County, preparation should reflect the older adult’s individual needs. A senior who uses a walker or takes several medications may need a different emergency plan from someone who lives independently without additional support.
The goal is to build practical readiness gradually, protect essential routines where possible, and make sure family members and caregivers understand what to do.
Why Cascadia Earthquake Preparedness Matters for Older Adults
A significant earthquake may affect buildings, roads, bridges, utility services, and local communication systems. Emergency responders may not be able to reach every household immediately, so families should plan for the possibility of managing without normal services for at least two weeks.
Older adults may face additional challenges, including:
Mobility limitations: Damaged walkways, fallen objects, or blocked exits can make moving around difficult.
Medication needs: Pharmacies may be closed, deliveries delayed, or prescriptions difficult to refill.
Medical equipment: Some devices depend on electricity, replacement supplies, or reliable charging.
Memory or cognitive changes: Confusion and disrupted routines may make emergency instructions harder to follow.
Sensory limitations: Hearing or vision changes may affect access to alerts and emergency information.
Social isolation: A person who lives alone may have difficulty contacting family or requesting help if phone services fail.
These concerns do not mean an older adult cannot prepare successfully. They mean the plan should be individualized and practiced before an emergency occurs.
1. Create an Emergency Plan Around the Senior’s Daily Needs
Start by reviewing the older adult’s normal day. Identify what they need to remain safe, comfortable, and able to communicate if essential services are interrupted.
Consider questions such as:
Can the person get out of bed and move safely without assistance?
Do they use a cane, walker, wheelchair, or other mobility device?
Do they need help with meals, personal care, or medication routines?
Can they understand emergency instructions independently?
Do they depend on powered medical equipment or refrigerated medication?
Who can check on them if roads are blocked or phone service is unavailable?
Write down the answers and use them to develop a practical plan.
Include the senior in decisions whenever possible. Explain the purpose of preparations in a reassuring way, and focus on maintaining safety and independence rather than creating fear.
The plan should also identify an alternative place to stay if the home becomes unsafe or essential services cannot be restored promptly.
2. Build a Two-Week Emergency Supply Kit
Oregon’s “Be 2 Weeks Ready” guidance encourages households to prepare enough food, water, and essential supplies to manage for at least two weeks following a major disaster.
For an older adult, a standard emergency kit may need additional items based on health, mobility, communication, and dietary needs.
Start with these essentials:
Drinking water and supplies for basic hygiene.
Shelf-stable foods the senior can chew, swallow, and digest comfortably.
A manual can opener, if needed.
Flashlights, extra batteries, and a battery-powered or hand-crank radio.
A first-aid kit and basic hygiene supplies.
Warm clothing, blankets, and sturdy footwear.
A portable phone charger and backup power options compatible with the person’s devices.
Copies of important contact information and relevant medical details.
Cash in small denominations in case electronic payments are unavailable.
Supplies for service animals or household pets.
Store supplies where they are easy to reach and unlikely to be blocked by heavy furniture. Avoid placing an emergency kit in a location the senior cannot access without assistance.
If gathering two weeks of supplies at once feels overwhelming, build the kit gradually. Add a few items each week and check expiration dates regularly.
3. Prepare Medications and Medical Equipment
An interruption in pharmacy services or electricity can be particularly concerning for people who depend on regular medication or medical equipment.
Families should work with the senior’s healthcare providers and pharmacist to develop a safe contingency plan.
Helpful steps include:
Maintaining an up-to-date medication list with medication names, doses, and prescribing providers.
Keeping prescription information and pharmacy contact details in a waterproof container.
Asking the pharmacist about refill timing and options for emergency disruptions.
Storing medications according to their specific instructions.
Identifying which medical devices require electricity, batteries, or consumable supplies.
Checking manufacturer guidance for backup power and safe equipment use.
Keeping essential supplies, such as hearing-aid batteries or mobility-device accessories, available when appropriate.
Do not change medication doses or storage conditions without appropriate medical guidance. Some medications require refrigeration, and not every medication can safely be stored in an ordinary emergency kit.
For powered medical equipment, ask the healthcare provider or equipment supplier about backup arrangements. Families should also contact their electricity provider to learn whether any medical equipment support or emergency notification options are available. Do not assume enrollment guarantees uninterrupted power.
4. Make the Home Safer Before the Ground Shakes
Preparing the home can reduce the risk of injuries from falling objects and help preserve access to essential areas after an earthquake.
Walk through the home with the older adult and identify hazards that could cause problems during shaking or afterward.
Prioritize these actions:
Secure tall bookcases, cabinets, televisions, and other heavy furniture using appropriate hardware.
Move heavy or breakable items to lower shelves.
Keep frequently used supplies within comfortable reach.
Clear hallways, bedroom exits, and routes to bathrooms.
Secure items that could fall onto beds or favorite seating areas.
Identify safe places in rooms away from windows and objects that could fall.
Keep sturdy shoes and a flashlight near the bed, where they can be reached safely.
Learn how to shut off utilities if appropriate, and only do so when it is safe and necessary.
Avoid storing heavy emergency supplies on high shelves. A kit that cannot be reached safely during or after an earthquake will not be useful when needed.
If the home has structural concerns, consult an appropriately qualified professional about possible improvements. Older adults who rent should ask their landlord about relevant safety concerns and permitted modifications.
5. Adapt Earthquake Safety Instructions for Limited Mobility
Standard earthquake guidance recommends Drop, Cover, and Hold On. However, not everyone can safely get down to the floor or crawl under furniture.
Oregon Health Authority guidance includes adaptations for people with mobility limitations.
If the senior cannot get onto the ground safely:
If seated, remain seated if that is safer than attempting to stand.
If using a wheelchair, lock the wheels when possible.
Protect the head and neck with the arms, a pillow, or another accessible protective item.
Move away from windows, glass, and objects that could fall, if this can be done safely.
If a sturdy table or desk is immediately accessible, use it for protection when practical.
Follow the person’s individualized safety instructions and avoid risky transfers during shaking.
Caregivers should not attempt to carry an older adult across a room while the ground is shaking. That can put both people at risk of serious injury.
Practice the adapted response during a calm moment so the senior and any regular helpers know what to do. For specific mobility or transfer concerns, ask a healthcare professional or occupational therapist for guidance.
6. Establish a Communication and Check-In Plan
After a major earthquake, cellular networks may be overloaded, internet access may fail, and family members may be unable to travel.
A communication plan should identify how the senior will contact others and how relatives will check on them.
Include:
An out-of-area contact who can relay information among family members.
Printed telephone numbers in case a mobile phone is lost or discharged.
A designated meeting place if household members become separated.
A backup plan if the primary caregiver cannot reach the home.
A method for receiving emergency information, such as a battery-powered radio.
A list of trusted neighbors who may be able to check in when it is safe.
Families in Portland can also review the city’s emergency preparedness information for people with disabilities. Depending on where the senior lives, local alert services and community preparedness programs may offer additional resources.
Do not depend entirely on text messages or a single person being available. Multiple ways to communicate provide more flexibility when services are disrupted.
7. Coordinate Family Members and In-Home Caregivers
If an older adult receives regular assistance at home, family members should discuss earthquake preparedness with the care team before an emergency occurs.
Clarify which tasks are part of the agreed care arrangement and which responsibilities belong to relatives or other designated contacts.
A useful planning conversation may cover:
Where emergency supplies are stored.
How the senior responds to alarms and urgent instructions.
Which mobility devices or medical supplies are essential.
Who will contact family members after an earthquake.
What to do if the caregiver cannot travel to the home.
How to document important observations and communicate urgent concerns.
Caregivers should not be expected to perform unsafe lifting, transport a senior through hazardous conditions, or provide medical services outside their training and responsibilities.
It is also important to have a backup contact. A family member may assume a caregiver will arrive as usual, while the caregiver may be unable to travel because roads are damaged or their own household needs assistance.
A realistic plan acknowledges these limits and identifies alternatives wherever possible.
8. Review and Practice the Plan Regularly
Preparedness works best when it becomes part of ordinary household routines rather than a task postponed until an emergency seems imminent.
Set aside time every few months to review the plan and check the supplies.
Use this checklist:
Emergency supplies are available and accessible.
Food and water supplies are checked and replenished.
Medication and medical-equipment plans are current.
Heavy furniture and potential falling hazards have been addressed.
The senior knows an appropriate protective action for each frequently used room.
Family members and backup contacts know their roles.
Important telephone numbers are available on paper.
Emergency information can be accessed without internet service.
The plan reflects current mobility, memory, and support needs.
Practice should be adapted to the older adult’s abilities. The purpose is to build familiarity, not to create distress or risk injury.

Helping Aging Adults Prepare With Confidence
Cascadia earthquake preparedness can feel like a large undertaking, especially when an older adult already needs help with daily activities. Families do not need to accomplish everything at once. A few practical steps, repeated over time, can build a stronger foundation for safety.
Start with the senior’s individual needs, organize essential supplies, prepare for medication and power interruptions, and make sure family members know how to communicate when normal services are unavailable.
