THE LATEST IN THE GEOSCIENCES
This week in geology
- Earthquakes in Salt Lake City, Utah
This week in the environment
- Florence is on its way
When people think of earthquakes, Utah (United States) is not the first part of the world to come to mind. I mean, yes, Utah is notable for may reasons, but earthquakes is not one of them.
However, the Wasatch Front – the relatively straight mountain range along the eastern border of the Salt Lake Valley – is actually formed by massive faults that parallel the mountain ranges.
Unlike the San Andreas fault (in California), which is almost continuously active, the faults along the Wasatch Front tend to only move once every couple thousand years or so. And when the Wasatch faults move, they move BIG. Like 50 foot fault scarps big.
So while California gets all the press for earthquakes, Utah is due for a big one and it’s gonna be amazing. Despite the general quietness of the faults in Utah, there still is motion and the occasional tiny earthquake.
Florence was downgraded to a category 1 hurricane just as it made landfall, but flooding continues days later.
