Swarm Continues In Central California

The USGS is reporting four quakes occurred yesterday September 19th near the Long Valley Caldera. The largest quake registered 3.9 magnitude.
In addition to the swarm near a very large volcano range around Mammoth Lake, a very strange occurrence happened 30 miles from Aspen, Colorado. The USGS is reporting a rare 3.5 magnitude quake occurred yesterday around the time of the California swarm. But that is not what caught my attention. The depth of the quake as reported by the USGS was 1.0 kilometers. It other words, just below the surface.
The USGS is now reporting the 3.5 mag. quake in Colorado was “probable mining induced event.” Oh boy, here we go again. I better rush over to the Yellowstone survey board to see what’s going on. Just returned; Yellowstone appears quiet at the moment.
Solar Weather Update:
A new M-Class flare erupted yesterday. I expect to see the Kp index rise within 48 hours. Possible influence as it hits the Earth’s magnetic field is the escalation of current hurricane and tropical storm activity. There is a slight chance of high latitude auroras on Sept. 21st as a result of a ‘lopsided CME delivering a glancing blow to Earth's magnetic field.
