In addition to yesterday's earthquake in Virginia, there was also one in Colorado yesterday. With two in 24 hours, some are concerned about more. It was 1993 that two major earthquakes near Klamath Falls caused 2 deaths and 7 million dollars in damage. Those quakes were magnitude 6.0 and 5.9. Experts say that despite the Colorado and Virginia earthquakes, there is no worry about a ripple effect on the West Coast.
