You hear a lot about the dangers of tsunamis associated with earthquakes, with good reason. But fires are the second most dangerous hazard involved in an earthquake.
Let’s look at why earthquakes often cause damaging fires and how you and yours can remain safe after it’s passed.
Why do earthquakes often cause damaging fires?
An earthquake itself happens when two tectonic plates collide and cause ground shaking.
When an earthquake happens, fires are often a result because it causes the ground to rupture, which leads to landslides and other hazards. Gas lines and electricity infrastructure suffers the most.
It Only Takes a Spark
Gas lines are especially at risk, but when the earth ruptures, it will break the lines. When gas builds up in any area, all it takes is a spark, and a full-on fire has begun.
If a fire starts due to a gas leak, it needs to be put out immediately to keep it from spreading and doing further damage. You must try to suffocate the fire using whatever you have on hand.
- woolen cloths
- fire extinguisher
While you can try and fight the fire yourself, always call emergency services ASAP.
Get Away from Gas Leaks
- Call emergency services and leave the area immediately if you suspect a gas leak.
- Phone lines might be down, and that leaves you in charge. Let everyone knows what’s up and evacuate the area.
- Never return to the scene of a gas leak until you get the thumbs up.
The Fires That Follow
An earthquake’s aftermath will always bring chaos, including downed lines, trees, and leaking gas pipes.
Downed electrical lines cause a power outage, and the broken lines can also start a fire. Property and infrastructure have already taken on damage, which makes them prime to catch aflame.
If You’re Trapped After an Earthquake
You’re not always going to have time to grab the whistle out of your emergency to-go bag. You will have to rely on tapping and banging on pipes and walls.
Shouting is dangerous because of the things you could inhale that will do damage to your lungs, including smoke. But you may not always have a choice.
Your phone likely has an SOS sound. Now is the time to blare your phone to get someone’s attention.
Things Fall Down
Another consequence of an earthquake is that objects can fall into heaters, fireplaces, and lit stoves. It leads to house fires that can spread into entire neighborhoods.
Always put out any open flame in the minutes following an earthquake.
Are fires likely after an earthquake?
Shake damage is the most likely damage during and after an earthquake. An earthquake ups the chances of a fire breaking out, though.
How do I prevent fire damage from an earthquake?
You can’t prevent an earthquake, but you can take steps to prevent a fire.
- Turn off all of the gas in the building or home.
- Grab the fire extinguisher in your fire emergency kit and have it ready, just in case.
- Any fire or hazardous material needs to be secured and safely stored.
- Don’t use your gas-run appliances until you’re in the clear.
Earthquake Warning System
What caused the fires in the 1906 San Francisco earthquake?
Water and gas mains broke open during the 1906 San Francisco earthquake, which led to a massive gas leak.
Because the water lines broke, too, there was no water to put out the fires to which the leak was the catalyst. The earthquake and resulting fires did $500 million in damage – in 1906.
Did the Haiti Earthquake 2010 cause fires?
Almost all earthquakes cause some sort of fire. In the Haiti Earthquake in 2010, massive structural and foundation damage were the biggest concerns.
But, fires and nonstructural damage added to the $2 billion cost to repair.
What causes fires to ignite after an earthquake?
- A spark happens during a gas leak which leads to a fire or even an explosion.
- Fires typically happen after an earthquake because of down electrical lines and broken gas lines.
- Home decor and other objects can fall into an existing flame or hot spot within a home.
Plan Your Earthquake Emergency Response
Preparedness means you have a leg up on any emergency event, including an earthquake.
Drop, Cover, and Hold On
You will want to practice Drop, Cover, and Hold On with family members and coworkers, so they know what to expect.
- Drop. You want to get down and under a sturdy desk or table. While under there, grab onto a leg of the furniture.
- Cover. The head is the most delicate part of our body, which means you will want to cover it and your neck under the desk or table. If you can’t find a sturdy piece of furniture, just cover your head and neck with your hands and arms.
- Hold. You are staying there, sheltering in place, until the shake completely stops.
Aftershocks are likely to happen. The more minor earthquakes will cause further damage, and you need to be prepared to drop, cover, and hold again.
Family Emergency Plan
An emergency plan must include contact from out-of-state for this exact scenario. You will want to put a plan in place in case you’re separated.
How to Stay Safe During an Earthquake
- If you get caught in bed, roll facedown and stack as many pillows as you can atop your head to protect it and your neck.
- Get off the road if possible. The violent ripples of an earthquake can cause buildings and bridges to collapse and create other serious road hazards. Pull over, stop, and set your parking brake.
- People caught outdoors during an earthquake should always steer clear of buildings and other structures. At any point, something could fall or catch fire after an earthquake hits.
- Don’t run outside during an earthquake. The only exception is if the building has obvious damage and is possibly at risk of falling or catching fire.
- Stay away from doorways, regardless of what you’ve heard.
Earthquake Emergency Supply Kit
A well-stocked emergency kit can mean the difference between life and death. You are the first responder. Emergency response teams will be stretched to their limit during an earthquake.
You can prepare and protect your home from earthquake and fire damage.
All bookshelves, fridges, heaters, TVs, and hanging objects all require securing if they’re to escape an earthquake in one piece.
It never hurts to check for structural issues before an earthquake happens. You can consult with earthquake professionals and do the updates needed.
People that live in Earthquake zones will always benefit from having earthquake insurance on their side.
Standard homeowner’s insurance will not cover earthquakes unless you specify and pay the additional cost.
