Prepping for The Big One: What to expect, what to have on hand, and what to do when an earthquake hits
At 4:35 a.m. the ground heaved.
It shook Susan McLaughlin, seven months pregnant, and her husband, Scott Boetjer, out of their sleep in a suburb of Christchurch, New Zealand. "We ran out of the house, afraid it would slide down the hill with us in it," McLaughlin remembers. She fell down some stairs, but did not seriously injure herself or her unborn baby. Boetjer sustained a gash on his leg. "We did what we shouldn't do. We later learned it's safer to stay inside until the shaking is over," she adds.
McLaughlin, who now lives in Seattle's Queen Anne neighborhood with her family, recalls the immediate aftereffects of the quake: "When the sun broke through, we started walking." The effects of the magnitude-7 earthquake were everywhere. There were bricks all over the streets, massive visible cracks in the buildings, and bits of façades continuing to fall in the continuing aftershocks. "People were listening to their radios in their cars," McLaughlin says. "We didn't have a car, so we couldn't do that."
Although she'd lived in California for ten years, McLaughlin and her husband didn't have earthquakes on their radar when they had moved to New Zealand eight months earlier. "We wished we'd stockpiled water; we wished we'd had a battery-powered radio," McLaughlin says, remembering that they were without a reliable source of water for over a week. "We did have flashlights and a first aid kit." They had no power and no cell service either.
As aftershocks to the quake continued, including another major earthquake on December 26, 2010, the couple stockpiled water and food and moved closer to the center of the city to be near the hospital in case roads were closed when McLaughlin went into labor. They were out of town with their 7-week-old son Logan when the most devastating aftershock occurred on February 22, 2011. This earthquake was less intense – 6.3 on the Richter scale – but was shallower and closer to the center of the city, so damage was much greater: 185 people died.
They flew back home to Christchurch the next day; McLaughlin, as an urban planner and designer, had to be involved with the recovery efforts. "It was a war zone," she remembers. Thankfully, their house remained intact and passed inspection to be habitable. "We were lucky," she says.
Boetjer stayed home with Logan while McLaughlin worked, but cell phone service and communication lines were always at risk of going down during daily aftershocks. On a few occasions, Boetjer would meet his wife at the government buildings to check if everyone was O.K. With broken sewage lines, the mayor instructed people to dig holes in their gardens to use the bathroom. "It was a huge challenge to clean Logan's clothes and reusable diapers in buckets, with no running water," McLaughlin says. They switched to disposable diapers, but had to drive 20 miles to find them. "Thank goodness I was still nursing," she adds. "We had enough food for us – it wasn't necessarily tasty, and fresh produce was hard to come by."
After a few weeks, restoration efforts to Christchurch's infrastructure began and life slowly improved. Still, the state of emergency, with limited city services, lasted for more than two months. Aftershocks continued, with the last of the four major earthquakes occurring in June of 2011.
Be prepared for the big one
McLaughlin, who works for the City of Seattle's Department of Transportation downtown, has agreed to be a resource for the Puget Sound Offices of Emergency Management's "What to Do to Make it Through" campaign.
Her experiences illustrate the campaign's main thrust: that residents need to plan to survive for seven to 10 days in the event of a major catastrophe. "Previously we'd been doing emergency campaigns advising people to stockpile supplies for two or three days," says JoAnn Jordan, public education coordinator at the Seattle Office of Emergency Management. "The reality is that for major events, it could take from several days to more than a week before essential services, such as running water, electricity and phones, are restored."
A major earthquake – "The Big One" – first comes to mind when we think of possible catastrophes. The Puget Sound area is atop the Cascadia Subduction Zone, one of the most dangerous faults on earth. Our earthquake risk is the third highest in the nation, behind California and Alaska.
The United States Geological Survey says there is a 87.561 percent chance of a major earthquake (magnitude 5 or more on the Richter scale) within 50 miles of Seattle within the next 50 years. It is impossible to predict whether the next one will be truly catastrophic: The 1949 quake (7.1), the 1965 quake (6.5) and the 2001 Nisqually quake (6.8) did not cause anywhere near the damage or loss of life experienced in Christchurch. However, a nearly 9-magnitude earthquake struck the Puget Sound area in 1700 and would have virtually destroyed any cities.
Below, we dive into questions about what to do when the earth shakes, how to plan and communicate when the shaking ends, and how to survive without city services for a week or more.
What to do when the ground shakes
"Despite what Hollywood shows, people don't usually panic in a disaster; they do what they perceive is right," Jordan says, speaking from more than 20 years' experience in disaster preparedness education. "So it's good to know ahead of time what the right thing is." Her tips:
If you are in a building, stay there. Most of our buildings, including high rises, will do well in an earthquake, even if they sway.
"Drop, cover and roll" is still a good guideline: Drop to the floor, cover your face and tuck your body into a ball. Your head should not be the tallest thing in a room.
Try to get "beneath, beside or between": Get beneath a large piece of furniture like a dining room table if possible; if not, get beside an inside wall or large secured bookcase; if you're in an auditorium or church, get between the rows of chairs. Always face away from glass windows or mirrors.
If you're in bed and are awakened from a deep sleep, stay in bed and cover your face. Have shoes with hard soles next to your bed at all times so that you won't be cut by broken glass when you get up.
If you are outside, stay there. The most dangerous place to be is right next to a building where things are likely to fall off, and people get hurt trying to run in or out of doorways. The exception is on a street with tall buildings where the "fall zone" is wide – then it's best to get into the closest building.
If you are outside away from buildings, sit down and make yourself as small as possible. Most trees will not fall in a quake.
If you are in your car, it will feel as though all the tires have gone flat. Pull over, stop and stay in your car. If you are on a bridge or under an overpass, drive away if possible. In any case, you are safer in your car than you will be if you get out and run.
Although McLaughlin says she does not live in fear of earthquakes, "but I'm so ridiculously aware of my surroundings at all times. In meetings or anywhere I go, I'm asking myself, ‘What's above me? Where can I get out if I need to?"
Planning for the moments after a quake
"I think we put too much emphasis on stuff and not enough on planning when we think of preparing for catastrophes," Jordan says.
There are two things we can do ahead of time to make our homes safer. The first is bolt anything tall and heavy to the wall. "There were awful stories in Christchurch about things falling on children and crushing them," McLaughlin says. The second thing is to walk the pathways of your house and ask yourself, ‘If an earthquake happened in this room, where would I go?'" Jordan says.
We will need to plan ahead to communicate and receive information once the shaking stops. Cell phones probably won't work and landlines can be overwhelmed. "If everyone tries to get on the phone at the same time, it's like Mother's Day to the 10th power and the system will crash," Jordan says.
Emergency planners want people to stay off all phones for three to five hours unless they need to call 911 for a life-threatening emergency. (The only death in the Nisqually earthquake was a heart attack victim who could have been saved if his family had been able to get through on 911, Jordan mentions).
Families should identify an out-of-area number to call to check in, and each member of the family should have a card with the number on it. The out-of-area contact can then tell everyone how other family members are faring and where they are. You can make that call from a landline that is connected to the wall – not a cordless phone. If you don't have one, you should know ahead of time who has one in the neighborhood. If you need to use a cell phone, text messaging is the most efficient way to get in touch, Jordan adds.
If the power is out, the television and Internet won't be a source of information. You should have a battery-powered, solar-powered or hand-cranked radio (with extra batteries if needed). The official emergency station is KIRO 710 AM. KOMO 1000 AM is also usually reliable, Jordan says.
It's important to designate an outside spot where your family will meet if you have to get out of the house or if people can't get home. Streets may be impassable, and you may not be able to communicate with children and spouses right away. That's why it's important to know – or help to prepare – the survival plans of children's schools and daycare centers to ensure that they are safe if they need to stay put for a while, Jordan says.
Be in contact with neighbors ahead of time to know who may be vulnerable and need to be checked on and who has supplies that can be shared, such as barbecues (with stored briquettes) and camping stoves (with fuel) if power is out.
Stock supplies for 7 to 10 days
The first thing to ask is, "If I had to grab and go, what would I need to survive right away?" Jordan says. She advises placing a suitcase on wheels or other carrier near an exit and putting in emergency supplies for a day or so.
Within the house, keep the following supplies. It may not be possible to put them all in one place, but know where they are:
Water: one gallon of water per person per day, for drinking and sanitation
Food: seven to 10 days of non-perishable foods per person and pet
Cash: small bills are best (ATMs won't work without electricity)
Battery-powered radio and extra batteries
Flashlight and extra batteries (no candles)
First aid kit
Whistle to signal for help
Filter mask or cotton t-shirt to help filter the air
Moist towelettes for sanitation
Wrench or pliers to turn off utilities, if needed
Manual can opener
Shelter items like tents, tarps and rope
Garbage bags and plastic ties for sanitation
Unique family needs: supplies for infants, pets and elderly; prescriptions; important family documents.
Critical documents include birth certificates, social security cards, real estate contracts, insurance contracts, bank records and passports/identification documents. Make copies and save them with your kit and in a safe deposit box. If possible, save files on a USB drive and keep them in both locations.
The emergency managers suggest starting with your home kit, then creating additional kits for your car, office and pet.

The biggest thing I hear about preparing for a catastrophe is: ‘I don't have time. I don't have money. I don't know where to start," Jordan says. "Ask yourself, ‘If a disaster happens tomorrow, what is my biggest concern?' Begin to address that within 24 hours, and then tackle the other things one at a time."
"Having a child and feeling unprepared is an awful place to be," McLaughlin concludes. "Doing simple things – like making a kit for my husband, son and me – makes me feel much more prepared for an earthquake or other disaster now."
