One of the basic rules of living in an earthquake zone is to avoid having loose objects that would cause great danger if they fell, right? Do you store unsheathed swords sitting loose on the top shelf, or unattended loose boxes of live rattlesnakes on the coffee table, or armed land mines sitting loose on the kitchen counter? Certainly not. Got unattended fire on the table while you are in the other room or away from home? Of course not! ...Except that many people do, even near earthquake faults, in the form of holiday or commemorative candles.
One poorly timed earthquake, and those people will have to consider themselves lucky if they just burned down their own home and not the entire city block.
Consider: candles in jack-o’-lanterns, candles in menorahs, memorial candles, etc., can change in an earthquake from fun, beauty, and devotion, to destruction and death; not just by falling themselves and starting fires, but also if some other object falls onto the candles and catches on fire.

The purpose of this article is to get you thinking about things that you may have taken for granted your entire life, but that could cause a destructive fire in the event of an earthquake; and about strategies for avoiding that risk.

Many Jews light candles in menorahs over the eight-day holiday of Chanukah. Tradition strongly prefers candles (or olive oil) over the widely available electric menorahs because the holiday commemorates the miracle of a tiny bit of oil keeping the Temple’s seven-branch menorah burning. The Chanukah menorah light is supposed to be supported by a fuel reserve of at least 30 minutes, and electricity from power outlets is considered to be constant rather than a reserve, so it doesn’t satisfy this requirement. Battery powered menorahs could fit the description, but my research turned up many examples of religious authorities not being satisfied with electric lights for Chanukah, saying that they are appropriate only for decoration.

Another Jewish tradition: Yahrzeit candles are small candles that burn for a little over 24 hours and are lit each year on the anniversary of a loved one’s death (see earlier photo), with similar candles burning for the first week of mourning. Given that they are supposed to burn for 24 hours, you presumably need to leave them unattended while asleep or at work or away for other reasons. That’s a whole 24 hours in which an earthquake could turn your remembrance of tragedy into a new tragedy. Since people keep each candle lit for a whole day, and there are ~365 days/year, roughly one out of every 365 people who light Yahrzeit candles will have one lit at any given time. That means the odds are nearly certain that a huge number of Yahrzeit candles will be lit and unattended during any earthquake that occurs.
Since all of these Yahrzeit candles will be burning unattended during any earthquake, the chances of one starting a fire during a quake are pretty good!

I’ve got several Jewish examples here because of my own familiarity and because candles are so pervasive in Jewish traditions. Once each week, shortly before sundown, observant Jews are supposed to light “Shabbat” candles and I’ve seen several accounts on Judaism informational websites about lighting the candles, then going to services, then returning home for the Sabbath meal; and the people are not allowed to extinguish the candles.

Here are some distressing instructions from the Jewish content website aish.com: Q: “What if we won't be home for dinner Friday night?” A: “Light your candles at home if you will be returning to sleep there, as long as they will still be burning when you return home. Otherwise, light your candles at home and stay until after dark before leaving for your dinner ‘out.’ If you are afraid of candles burning unsupervised, simply light them in a sink that you won't be using during Shabbat!”
The first sentence in that quote gives me heartburn and could give them homeburn. At least they dealt with the problem at the end, and I suppose leaving lit candles in the sink avoids the problem of the candles falling in a quake, although there is still the smaller possibility that something falls into the flame, ignites, and then floats elsewhere and burns down your home.
What about electric alternatives for the Sabbath? I was somewhat surprised to find numerous references on the web stating that the consensus holds incandescent lights (I guess not CFLs or LEDs, but even this is debated), especially those powered by batteries (fuel reserve), to be an acceptable equivalent to fire for this purpose, such as this quote from a website about Jewish law that says: “However, in situations where lighting an open flame may be hazardous or subject to regulation, one may use electric lights. This is the case for patients in a hospital, or guests staying at a hotel...” Perhaps you can light real candles if you will remain at home and use electric candles if you plan to leave them unattended.
Another potential compromise is discussed at the end of an interesting article about the debate over electric Shabbat lights ...“Third, there is a certain element of danger in lighting actual candles, especially when left unattended. Incorporating electric lights into the candle lighting service provides a means of minimizing the danger. By incorporating electric lights, one can use a candle or oil that will only burn for a short amount of time, and the electric lights will fulfill the task of providing oneg Shabbat after the candles are extinguished.”
(There’s been at least one reported instance of an electric candle falling onto a carpet and burning a hole in it, so perhaps a dab of quake putty is still wise if it is above flammable surfaces.)
My bottom line: in earthquake regions, if you leave an open flame in your home while nobody is there, you are risking your home and putting your neighbors in danger. Hopefully by using the ideas in this blog, you can fulfill your traditional obligations without ignoring the realities of living in an earthquake zone.
Thanks to Rabbi Joel Landau of Adath Israel Congregation (Orthodox) and Rabbi Aubrey Glazer of Congregation Beth Shalom (Conservative) in San Francisco for helpful discussions about the Jewish traditions.

However, that probably isn’t even necessary, because unless the several references I found on the web were all incorrect, the daily ceremony of candle lighting involves extinguishing the candles at the end of the ceremony and then relighting them at the beginning of the next day’s ceremony, so they aren’t left unattended. I wish all candle traditions were this sensible!
The Indian festival of Diwali probably beats Jewish traditions with respect to fire. I know far less about Diwali than the Jewish traditions, but from what I have read, Hindus celebrate Diwali by lighting candles, oil lamps (diyas), and fireworks; and I’ve seen references on the web to releasing floating oil lamps into streams and to leaving flames burning all night. Jains and Sikhs have their own variations of this festival. By doing internet searches, one sees various references to destructive fires and to burn injuries, although these appear to be due to fireworks, rather than falling candles.

To my unsophisticated understanding of the issue, it sounds people can opt for electric lights or any other measures to avoid insufficient earthquake flame safety if they so choose, so please consider the issues in this article when deciding what kinds of Diwali lights will be unattended.
Christian votive candles
Then we have the whole range of votive candles in Western Christianity (some of which are lit in the home), and Eastern Orthodox Christianity (in many homes). I’ve seen discussions on the web about the use of electric candles for Catholics, and not surprisingly, there’s a whole range of opinions out there...but it sounds like electric votive candles are not that unusual and are generally allowed in Western Christianity. I saw one reference to a church switching to electric candles because their fire insurance premiums were much lower that way, surprise!

One interesting aspect of the Eastern Orthodox votive lamps that was unknown to me until Father Stefan described them to me is that frequently, these lamps are hanging, rather than sitting on a surface. To me, this would reduce the potential impact of an earthquake because the lamps could swing with the quake and then settle back to position at the end, rather than being knocked permanently off of the surface. Still, remember that in a major quake (think San Francisco, 1906), there is still a chance that they could come down if they fling off of their hook or if the structure holding the hanging lamp collapses itself. It might be worthwhile to directly fasten the chain to the hook rather than just hanging it on the hook, and to ensure that the part that holds the flame can't easily fall away from the part attached to the chain.
Middle Eastern and East Asian traditions
In contrast, my friends from different Muslim cultures tell me that Pakistani and Arab traditions don’t include religious candle burning. Toward the end of Ramadan, Iranian Muslims stay awake by candlelight or with dimmed room lights; certainly safer than lighting candles and going to sleep! For Muslims in Indonesia, Malaysia, and Burma, Eid al-Fitr at the end of Ramadan involves placing oil lamps outside of the home, and I am not sure if they are left burning unattended. While various East Asian cultures use candles as part of their shrines, I’ve been told that Japanese and Taiwanese homes typically avoid unattended flames due to safety concerns including earthquakes; a refreshing attitude. I’ve heard that Chinese celebratory candles are only lit during the celebrations. However, some (not all) Vietnamese Buddhists leave candles burning unattended at home shrines to honor the spirits of deceased relatives. I’ve been told that in some cases, they are unattended intentionally to let the spirits have peace. An earthquake could topple these unattended candles.
(Admittedly, this one paragraph covered a vast number of diverse cultures, and there could easily be traditional variations that I didn’t encounter.)
THE BIG PICTURE
The religious issues may differ from culture to culture, but the laws of physics are the same for all religions: shaking plus flame plus gravity equals fire hazard. Despite not being a religious authority, I’m going to go out on a limb and suggest that none of these religions would condone putting one’s home and one’s neighbors’ lives in danger. Traditions and religious obligations can be followed without ignoring special local circumstances, like a long and repetitive history of earthquakes.
Put another way, when asked to comment for this article, San Francisco Fire Department Chief Joanne Hayes-White made the following statement: “People would be surprised at how many fires we respond to that are caused by unattended candles, fires that cause millions of dollars in property damage, injuries and even deaths. Every one of those fires could have been avoided. Leaving an open flame unattended is never a good thing to do, under any circumstance.”
And that’s without earthquakes to knock them over.
“But Matt,” you protest, “seriously, what are the odds that an earthquake will hit during that one hour that I am leaving the candle unattended as I run my errands?” Well, here’s a variation of something I say in my talks about equating earthquake precautions with locking your door and carrying keys because your home might be robbed. In this case, consider that you lock your door whenever you leave even if it is just to run a 10 minute errand, not because you think a burglar will try to enter your home in the next 10 minutes, but because you want to ensure that IF a burglar ever does try to walk through your door when you are away, it will be locked.
Earthquake safety Rule Number One is to ensure that WHEN the next substantial earthquake strikes, you won’t have falling swords or rattlesnakes or land mines...or flames!
