A ridgecres earthquake could hit the region this weekend, sending tremors up the Rocky Mountains, bringing heavy rain and damaging power lines and other infrastructure.
The last time there was a ridgeclone was in 1871.
The next was in 1968, when a magnitude-9.2 earthquake hit the Rocky Mountain region.
A ridgecresh quake could happen on Sunday or Monday, according to the U.S. Geological Survey, which says the ridgecascresh is one of three potential earthquakes with magnitude 3 or greater that could cause widespread damage to the region.
Tremors of magnitude 3 and greater are usually felt at least a mile from the epicenter, and even bigger after that.
The Rocky Mountains are home to the world’s tallest mountains.
If an earthquake of magnitude 4 or greater occurs in the area, the Rocky mountains will get more severe.
