At 7:09 AM a magnitude 5.7 earthquake hit the Salt Lake City area with an epicenter near Magna Utah. This is the largest earthquake ever recorded in the Salt Lake Valley. The prior significant earthquake in the valley was in 1962 also centered near Magna.
During that earthquake I was in second grade and I remember our desks were bouncing on the lineoleum floor for many seconds. This one hit with a strong jolt that sent my stomach to the floor. Rather than drop, cover and hold on I ran to the window to see what was happening.
Here is the richter scale, It is logarithmic.Richter Scale - Measures the Intensity of Earthquakes. The quake that triggered the giant tsunami in the Indian ocean on December was measured at 9.7 on this scale.
