Hi All. The M>4.4 Burney quake is a normal quake. That means the motion of the fault was downward. There are 3 unnamed faults in the area. I�m almost sure which fault it occurred in. That would be the second fault from the right or from the east. All 3 faults are NW/SE trending.

The quake occurring where it did is almost certain to be associated with the �Walker Lane Belt� which is a section of California that is being pulled apart. The �Walker Lane Belt� starts near the southern end of Owens Valley at the edge of the Mojave Desert maybe a little further south.

This area has volumes of evidence of volcanic activity all over the place. You can�t walk anywhere without walking on lava. There are approximately 70 cinder cones located between Burney and Chester with some in the Eagle Lake area to the east. I wouldn�t be surprised if we get something in the Medicine Lake area, which is located in a rift called the Eastern California Shear Zone (ECSZ). I don�t expect anything much larger, but we could get a few more about the same magnitude. It�s one of those wait and see things. Don in creepy town
