SALT LAKE CITY -- Geologists say the last major earthquake along the Wasatch Front hit more recently than previously thought.
The Utah Geological Survey and U.S. Geological Survey say in a new study released Thursday that an earthquake about 500 years ago tore a deep gash along a 35-mile segment of the Wasatch Fault between North Salt Lake and North Ogden.
The Utah Geological Survey's Christopher DuRoss says the quake was likely a magnitude 6.5 or 7 -- large enough to cause major damage along the Wasatch Front if it occurred today.
Previous research had indicated the last major quake in the area was 800 to 1,500 years ago.
Researchers also found evidence of large earthquakes happening about every 1,500 years going back 10,000 years.
DuRoss says a major quake could strike the area at any time.
