SLC is also located along two major earthquake fault lines.
Last decent shake was in 2020, 5.7 on the RS was in Magna (West of SLC)
Nothing for you CA residents, but it certainly surprised us.
As a practical matter, homebuyers should be aware that some of the older neighborhoods have very charming brick houses (re: “unreinforced masonry”) that will NOT fare well in a large earthquake. They’re expensive to insure (normal home owner’s insurance won’t cover it) and policies are hard to find. My earthquake insurance is over $2k/yr, with an eye watering deductible.
Regular newer homes are much cheaper to insure against this eventuality.
Just something to be aware of.
