If the ground just shook hard or long, or the ocean has drained away, risen like a fast flood, or started roaring, do not finish this page. Protect yourself during the shaking, then get your pet and move immediately, on foot, out of the evacuation zone. If you have high ground you can reach, go to it. If your community is flat and has no high ground, go to the vertical evacuation structure or assembly area your officials have designated, and know which one that is before today; NWS’s instruction if you cannot reach a safe place is to “follow evacuation signs to safety or go as high or as far inland (away from the water) as possible.” The National Weather Service is unambiguous that a tsunami in that situation “could arrive within minutes” and that you should not wait for an official warning or for instructions. If you cannot find an animal in the time you have, go anyway, and report it to local animal control and shelters once you are safe. Come back and read the rest when you are on high ground.
This site has playbooks for hurricanes, wildfire, flood, tornado, earthquake, ice storms, and volcanic ash. Until now it had nothing on tsunamis, and that gap mirrors a larger one. Search for tsunami preparedness and you will find genuinely excellent federal and state guidance about zones, alerts, and high ground, written almost entirely as though nobody in the evacuation zone owns an animal. The National Weather Service’s tsunami preparedness page gives pets one line: “Include your pets in all your preparedness efforts.” As of this page’s publish date, the NWS pages on what to do during a tsunami and on understanding alerts contain no mention of pets at all. Ready.gov’s tsunami page mentions pets only in its site navigation menu, not in any of its guidance. Oregon’s Department of Emergency Management tsunami page has no pet mention.
Meanwhile the pet preparedness world, this site included, has built most of its evacuation advice around a vehicle. Carriers that fit a cargo area. Crates that strap to a seat. Kits sized to what a car can haul. For a tsunami, that entire assumption breaks, and it breaks in a specific, documented way.
Why a Tsunami Wrecks the Pet Plan You Already Have
The National Weather Service’s tsunami preparedness guidance puts it in one sentence:
“You should plan to be able to reach your safe place on foot if you can because of possible road damage, closed roads and traffic jams.”
Oregon’s Department of Geology and Mineral Industries, the agency that actually models coastal evacuation, goes further. On its Beat the Wave program page: “When the next great Cascadia Subduction Zone earthquake and tsunami occur, coastal residents and visitors will have 10-30 minutes to reach safety. Evacuation on foot will be the only means possible.”
Washington’s Emergency Management Division describes its outer coast as a place where “a tsunami could arrive just 10-20 minutes after a major earthquake.” The Alaska Earthquake Center describes near-field tsunamis, generated by nearby earthquakes or landslides, as giving people “minutes rather than hours to reach safety”, and notes that tsunamis generated by submarine and above-water landslides “can strike with no warning.”
None of those agencies are talking about pets. All of them are describing the exact conditions that decide whether your pet comes with you: not vehicle capacity, but how fast you personally can move uphill while carrying or leading an animal, over ground that an earthquake may have just rearranged.

The 10 Minutes Oregon Already Spent on You
The number that reorganizes a pet plan comes from a technical report rather than a safety brochure.
DOGAMI’s Open-File Report O-16-08 modeled pedestrian evacuation for Warrenton, Hammond, and Clatsop Spit in Clatsop County, Oregon, under a magnitude 9.1 Cascadia scenario. Two of its stated assumptions matter enormously to anyone with an animal:
- The walking-time maps were built for “a moderate walking speed of 4 fps (feet per second, 22 minutes/mile)”, which the report notes is “the standard speed for pedestrians to cross at signalized intersections.”
- The Beat the Wave maps model a “10-minute delay from start of earthquake before starting evacuation.” Those maps do not assume your speed the way the walking-time maps do. They “depict the minimum evacuation speed required to stay ahead of the wave”, which is the number you go and look up for your own address.
Read those together and the pet problem becomes arithmetic instead of anxiety. The model has already granted you ten minutes to stop shaking, get up, get organized, and get out the door. Everything you do with an animal in that window comes out of that same ten minutes: finding the cat, getting the cat into something, clipping a leash to a dog that has just experienced the worst thirty seconds of its life, going back for the carrier you left in the garage.
And then there is the speed. DOGAMI’s report states plainly that evacuation from the hardest areas “will be extremely challenging for the XXL1 scenario for those with mobility limitations (i.e., those travelling at speeds less than 4 fps).” XXL1 is the report’s maximum-considered Cascadia event, generated by a magnitude 9.1 earthquake.
Twenty-two minutes per mile is about 2.7 miles per hour. DOGAMI calls that moderate, and it is: it is roughly the pace a signal timer assumes when it decides how long a crosswalk stays green. It is not a jog. The point is not that the modeled speed is hard. The point is that it is the floor, and the report is explicit that people below it are the ones in trouble. Carrying twenty pounds of frightened, shifting animal is a mobility limitation, whether or not anyone has ever described it to you that way. And on a Beat the Wave map the speed your own block requires may sit well above that floor, because the color on those maps is the minimum speed you have to sustain, not a speed anyone is promising will be enough.
We want to be precise about what is ours and what is DOGAMI’s here. DOGAMI models people, not pets. It has never published a figure for how much a carried animal slows an evacuee, and neither has anyone else we could find. The 10-minute delay and the 4 feet per second are theirs and are quoted exactly. The application to pets, that your animal spends part of that delay budget and can push you under that speed, is our reasoning, offered as reasoning and not dressed up as a finding.
Find Your Zone and Your Walk Time Tonight
For most hazards on this site, prep means buying and packing. For this one the work is free and it happens on a map.
Check whether you are even in the zone, using your own state’s viewer. That is where mainland coverage actually lives, and it is the step to get right, because the national-sounding tools are not national. Oregon and Washington addresses are covered by the NANOOS NVS Tsunami Evacuation Zones viewer at nvs.nanoos.org/TsunamiEvac, built with DOGAMI and Washington DNR data. Alaska’s interactive hazard map is at tsunami.alaska.edu. If you are in Hawai’i or Guam, NOAA’s Office for Coastal Management and the Hawai’i Emergency Management Agency run an address-searchable evacuation zone viewer at tsunami.coast.noaa.gov; Maui County points residents to exactly that tool, telling people to “enter your address, identify if you’re in a red, yellow, or green zone, and plan ahead.” Its coverage is Hawai’i and Guam only, so a Pacific Northwest reader who starts there gets nothing back. Anywhere else on the coast, your state geological survey or state emergency management agency is the right first stop. Check home, work, and wherever your pet spends the day if that is somewhere else, because NWS is specific that “You may need to identify more than one safe place, depending on where you may be when you get a tsunami warning (e.g., home, work, etc.).”
Then get your walk time, not just your zone. A zone tells you whether the water reaches you. It does not tell you how long you have, and the walk time is the number that decides your pet plan. Washington’s Emergency Management Division and DNR publish Pedestrian Evacuation Walk Time maps alongside inundation maps. The NANOOS NVS Tsunami Evacuation Zones viewer, built by DOGAMI with the University of Oregon and NANOOS, covers Oregon and Washington communities and, per the agencies’ own announcement, provides “a custom map view showing your quickest street route to safety outside the tsunami zone after a local Cascadia earthquake”, including “the distance to safety and how fast you need to travel to escape the tsunami.” Alaska’s Earthquake Center publishes pedestrian travel time maps for communities with completed inundation studies, modeling evacuation by foot and accounting for ground cover, steep terrain, and other barriers.
DOGAMI’s Beat the Wave maps go one step further by coloring routes with “the speed that must be maintained from the starting point until safety is reached”, which is why the program’s public materials talk in terms of walk, jog, or sprint. DOGAMI also warns that “The quickest route may not be the obvious one, so it pays to study the map and practice your route”, and that some reports model which bridges are likely to fail.
Now do the pet version of that lookup, which nobody will do for you:
- Find your required speed or walk time from your actual front door.
- Decide honestly whether you can sustain that speed carrying your specific animal, or animals, over that specific distance.
- If the answer is no, the plan changes now, not on the day. That might mean a carrier you can wear instead of hold, or a route that trades distance for a gentler grade, or asking your local emergency manager about a nearer vertical evacuation option, or a neighbor who has agreed in advance to take one of your animals.
Households with more than one pet should run this math per animal rather than per household, the same way our multi-pet go-bag math treats supplies. Two cats is not one trip. If you genuinely cannot move everyone in one pass, our guidance on which pet to evacuate first exists precisely so that decision is made calmly in advance rather than in a stairwell.
Two Warnings, Two Completely Different Pet Plans
NWS draws a distinction that pet guidance almost never picks up: there are official tsunami warnings and natural tsunami warnings. In NWS’s words, “Both are equally important and suggest the potential for a tsunami that may cause widespread flooding. You may not get both types of warnings.”
Natural warning. You feel a strong or long earthquake, or the ocean acts strange (rising like a fast flood, or draining away suddenly to show the ocean floor like a very low tide), or you hear a loud roar from the ocean. NWS: “a tsunami is possible and could arrive within minutes”, and “Do not wait for an official tsunami warning or for instructions from local officials.” The Alaska Earthquake Center gives a usable threshold for the shaking version: “If the ground shakes for more than 20 seconds and it is difficult to stand, and/or the tsunami siren is heard, anyone within the inundation/flood zone should move to higher ground or a tsunami shelter.”
Official warning. Broadcast through local radio and television, marine radio, wireless emergency alerts, NOAA Weather Radio, NOAA websites, outdoor sirens, local officials, text alerts, and telephone notifications. NWS publishes four levels, and most pet guidance never gets past the top one. The middle two columns below are NWS’s own words. The third column is our reading of what each level means for an animal, not theirs.
| NWS level |
What NWS says it means |
What NWS says to do |
What that means for pets |
| Information Statement |
“An earthquake has occurred, but there is no threat or it was very far away and the threat has not been determined.” |
NWS lists no protective action for this level, adding only that “In most cases, there is no threat of a destructive tsunami.” |
Nothing changes. Note it and carry on. |
| Watch |
“A distant earthquake has occurred. A tsunami is possible.” |
“Stay tuned for more information. Be prepared to take action if necessary.” |
This is the staging level. Carriers out and open, leash and harness on the door hook, phones charging, everyone accounted for. Do not leave yet. |
| Advisory |
“A tsunami with potential for strong currents or waves dangerous to those in or very near the water is expected or occurring.” |
“Stay out of the water and away from beaches and waterways. Follow instructions from local officials.” |
Dogs off the beach, out of the surf, off jetties and river mouths, and keep them off. The hazard NWS names at this level is currents and waves dangerous to anyone in or very near the water, which is exactly where a loose dog goes. |
| Warning |
“A tsunami that may cause widespread flooding is expected or occurring. Dangerous coastal flooding and powerful currents are possible and may continue for several hours or days after initial arrival.” |
“Follow instructions from local officials. Evacuation is recommended. Move to high ground or inland (away from the water).” |
Secure every animal and walk your route. No assessment step, no second lap of the house. |
For a pet owner the natural and official cases produce two different plans, and conflating them is the failure mode.
Under a natural warning, you have no pack time. What comes with you is what is already on the animal, already by the door, or already on your back. There is no trip to the garage. There is no assembling a kit. If your dog’s leash lives in a drawer in a different room, your plan currently includes a detour you cannot afford.
Under an official warning for a distant tsunami, you may have hours and no shaking at all. That is a conventional evacuation, and everything this site says about pet go-bags applies: our DIY pet go-bag checklist covers the full list, and Ready.gov’s own recommendation is to build two kits rather than one, “one larger kit if you are sheltering in place and one lightweight version for if you need to evacuate.” A tsunami zone is the single strongest argument for that two-kit split we have come across, because the lightweight version is not a convenience here, it is the only version that will ever leave the house on foot.
One warning about the distant-tsunami case specifically: it can arrive in the middle of the night with no ground shaking to wake you. That is the scenario a NOAA Weather Radio with battery backup and county-level S.A.M.E. targeting is actually for, and it is the one channel that does not depend on your phone being awake, charged, and un-silenced.
