EARTHQUAKE FACTS HOMEOWNERS SHOULD KNOW

Normally, it’s not the shaking ground itself that claims lives during an earthquake. It’s the associated destruction of man-made structures and the other natural disasters earthquakes cause such as tsunamis, avalanches and landslides. In a city, your biggest earthquake threat is often the safety of your own home.

CHIMNEY DANGER

One structural engineer told the SF Gate: “Masonry chimneys are perhaps the most urgent earthquake hazard in older homes. The problem is that they’re likely to fall in even a modest shake. A rule of thumb is that brick chimneys extending more than 1 1/2 times their least width above the roof pose a hazard of collapsing above the roof, not to mention any possible hazard they may pose below the roof level. That’s less than 2 feet for a typical 14-inch-wide chimney.”

Be sure your chimney is safe, or have it removed. Simple as that.

GAS LINES

After an earthquake, damage to your gas lines can mean a gas leak on your property. Which you won’t detect, because you’ll have evacuated! Best case scenario, your home stinks and you have to air it out. Worst case scenario, it goes up in a fireball. To avoid the whole problem, consider having an earthquake gas shut off valve installed, if you don’t already have one.

EARTHQUAKES AREN’T JUST FOR HUMANS

Most of us know to have a first aid kit, supplies, and an emergency plan for the humans in the house. Do you have an appropriate first aid kit for your parrot, ferret, or dog? What about emergency food set aside? Do you have a “save our pets” decal in your window, just in case? Be sure to include pets in your emergency planning.

FEMA HAS A PREPAREDNESS CHECKLIST

Many families try to make their own checklist or plan for earthquake preparedness. There’s nothing wrong with that, but it’s extremely unlikely you’ll come up with a more thorough and useful document than this Compiled by the Federal Emergency Management Agency, this is more than a list. It includes diagrams that teach helpful skills, and much more.

DROP, COVER, AND HOLD

The old wisdom was that doorways were the safest place to be indoors during an earthquake. That is no longer true in most buildings, especially buildings in earthquake prone areas, or new construction. Now Your safest place to be is near the ground, under something solid. The new mantra is drop, cover, hold. Drop to the ground, gain cover by going under a table or other furniture, and hold onto your protective cover with one hand, protect your neck with the other.

Avoid Chimney Repair With Removal

When a home has a chimney, and something is awry with it, many homeowners only consider 2 options: fixing it or leaving it in place but declaring the fireplace unusable.

But there are two unexamined options: removing the chimney completely and replacing it with a safer style of chimney.

WHY REPLACE YOUR CHIMNEY?

No amount of repair will make a masonry chimney as safe as a metal one. Masonry chimneys are more likely to fall down and hurt or kill someone during an earthquake than any other part of the house. A full replacement means leaving that risk behind, and still enjoying your fireplace as you always have. It’s all gain, no loss.

WHY REMOVE YOUR CHIMNEY?

Chimney removal is another great option. Why do I call it “great”? Because no chimney means no risk of chimney fires, no risk of a falling chimney, no more place for rain to enter your home, or your hot air to escape in winter.

When having a chimney removed you can opt to remove it below the roof line (if it’s not along on exterior wall), and keep your mantel and firebox area indoors (decorative only). Or you can remove the entire fireplace system. This can create new space in your home, too. The chimney removal cost is often less than repair, and unlike repairs, you’re not going to have to do it again in a few years. No more chimney maintenance for you!

Sometimes a chimney is utilized to vent gas appliances that are connected to the metal flue liner. If your chimney is being used to vent gas appliances such as a furnace, water heater, or boiler, a vent will still need to penetrate the roof to carry the exhaust gases to the exterior after your chimney is gone. This doesn’t mean you can’t remove your chimney. Your chimney removal specialist can help you navigate this safely.
