In the Shasta area there appeared three quakes just around 1:50-2:00 am Sunday morning. When I checked here there wasn't anything about them, but for a Sunday that wasn't unusual. What is unusual however is the fact that they have disappeared. Can somebody confirm these events happening? There were three mag 2+ quakes at depths from 10 to 20 miles in a matter of minutes in a triangle area south of Mount Shasta City, north of Redding, and east of Weaverville.
