With recent geologic hazards like the North Salt Lake landslide, and Napa, California’s large earthquake, perhaps this “Glad You Asked” article can come in handy. Are you thinking of buying a home, and are wondering what geologic hazards are present at some of your prospects? Read for more information!
Although a 2003 geotechnical report warned of the potential for landslides at Eaglepointe Estates in North Salt Lake, a 2013 supplemental study made no mention of the clay bedrock flagged for attention in the first and that one geologist called “a notorious bad boy” for instability.
Another weekend gone by, and September on the horizon! Who got out into some cool geology this last weekend? Here’s an article for your Monday morning. While we cannot always avoid natural hazards and disasters, we can prepare to the best of our abilities. Check out this read for tips on reducing landslide risks around your home.
At the beginning of this month, a landslide in North Salt Lake destroyed one home and caused 27 others to be evacuated. People are rightly concerned about protecting their homes from disasters such as this. When things like this happen, we are all reminded that Utah is not immune to natural disasters. While we would drive ourselves crazy if we thought about the possibility of landslides and earthquakes every day, it is important to not live in complete denial either. We need to understand the risks and know what we can do to protect our homes against potential damage as best we can.
Homeowners in a mountainside community north of Salt Lake City feared a cracked ridgeline above their property would send a landslide crashing below. They alerted city officials, who hired crews that began to raze the slope but couldn’t prevent a rock and debris from breaking away and smashing into a home.
“The final failure is unpredictable,” he said of Tuesday’s slide. But, he added, a large crack in the ground opened at the crown of the slide a week before it let loose.
While many people may very much remember the 1983 Thistle Landslide, perhaps some of our newer geo friends to Utah are not familiar with the history surrounding it. Our Deputy Director Kimm Harty helps revisit the events of the slide in this KSL interview—check it out.
There are still a handful of houses stuck in water and time in Thistle, though they stopped being homes 31 years ago.
One of our geologists here at the Utah Geological Survey, Adam McKean, talks about the geological makeup of the hill in North Salt Lake that makes it prone to sliding.
Years before one home crumbled in North Salt Lake, the developer behind the project was given the approval by the city to build it.
Jessica Castleton, a Utah Geological Survey Geologist, talks in further detail on geologic hazard resources for homeowners and developers.

Concerns are mounting throughout the Wasatch Front following a landslide in North Salt Lake that destroyed one house and put others at risk.
