Residents in the Brentwood area got a rude wake-up call this week when a magnitude 3.5 earthquake rattled windows, knocked a few pictures crooked, and sent neighbors flooding into the street in bathrobes.
No major damage was reported, and by lunchtime most people had gone back to their normal routines.
But the shakeup is a useful reminder that "normal" in earthquake country comes with a price tag.
If you've been putting off an emergency kit because money is tight, you're not alone.
A recent survey found that roughly half of American households don't have basic disaster supplies on hand, and the top reason is cost.
The good news: you don't need a $500 prepper bunker.
You need water, a flashlight, a first aid kit, and a plan — and most of that can be assembled for under $100 if you shop smart.
The standard advice is one gallon per person per day for at least three days.
A case of 24 half-liter bottles runs about $6 to $8 at big-box stores, and a 5-gallon refillable jug is often under $20.
If you already buy bottled water in bulk, you're halfway there.
Just rotate your stash so nothing sits past its date.
A basic LED flashlight is $5 to $10, and a hand-crank model costs a bit more but never needs batteries.
Skip the fancy solar generators unless you have medical equipment that requires power — for most homes, a few battery packs and a car charger will get you through a multi-day outage.
Grocery stores and hardware chains regularly discount these items during emergency-preparedness sales, usually in spring and fall.
You don't need freeze-dried meals at $10 a pouch.
Canned soup, peanut butter, protein bars, and crackers from your regular grocery run work fine.
Aim for a three-day supply of things your family actually eats, and buy a few extra cans each week instead of one big haul.
That spreads the cost across your normal grocery budget instead of hitting you all at once.
One more thing people forget: documents and cash.
After a quake, ATMs and card readers can go down.
Keeping $50 to $100 in small bills at home, plus copies of ID and insurance papers in a ziplock bag, costs almost nothing and saves enormous headaches.
Renters should also look into renter's insurance, which often runs $15 to $25 a month and covers personal property that a landlord's policy won't.
If you own an older home, a seismic retrofit can run several thousand dollars, which is out of reach for many families.
But some states and cities offer grants or low-interest loans for retrofit work, and even anchoring a water heater — a few hundred dollars — can prevent a fire or gas leak.
Check your utility and city websites before assuming you can't afford it.
But the households that fare best in the big one aren't the ones that spent the most.
They're the ones that spent a little, early, and didn't wait for the ground to move before thinking about it. **The bottom line:** Preparedness is a budgeting problem more than a survivalist one.
Final Thoughts
Spend $20 a month building your kit, and you'll be covered without wrecking your grocery budget.
