The realtime computer system detected and located two small earthquakes in the Sierra Nevada south of Long Valley caldera since the last update at 11:25 AM on July 8. Both had magnitudes under 2.0.

The realtime computer system detected and located eight small earthquakes in the vicinity of Long Valley caldera since the last update at 12:00 PM on July 11. The largest was a M=2.0 earthquake at 12:33 AM on the 12th located in the Sierra Nevada 10 miles SW of Tom's Place.
Three of these earthquakes had locations beneath the Inyo Craters between Wilson Butte and Obsidian Dome (M=1.5, 1.2, and 1.5 events at 12:14 AM on the 11th and 12:40 and 12:48 AM on the 12th, respectively). The Inyo-Mono Craters have produced very few earthquakes over the past 25 years.

The realtime computer system detected and located two small earthquakes in the vicinity of Long Valley caldera since the last update at 9:15 AM on the 12th. Both were in the Sierra Nevada south of the caldera and both had magnitudes less than M=2.0.

The realtime computer system detected and located four small earthquakes in the vicinity of Long Valley caldera since the last update at 9:10 AM on the 13th. All were located in the Sierra Nevada south of the caldera and all had magnitudes M<2.
NOTE: Network outages from the afternoon of the 9th (Saturday) through the 11th (Monday) compromised the capibility of the realtime system. As a result, the number of earthquakes reported during this interval is roughly half the number that actually occurred with magnitudes M<2.0. Visual inspection of the seismograms indicates that the "missed" events were all located in the Sierra Nevada south of the caldera.

The realtime computer system detected and located three small earthquakes in the vicinity of Long Valley caldera since the last update at 9:10 AM on the 13th. All were located in the vicinity of Grinnel Lake (~10 miles SW of Tom's Place)in the Sierra Nevada south of the caldera and all had magnitudes M<2.

The realtime computer system detected and located 11 small earthquakes in the vicinity of Long Valley caldera since the last update at 9:35 AM on the 15th. All but one were located in the Sierra Nevada south of the caldera. The largest of these included M=2.3 and M=2.2 earthquakes at 5:35 PM on the 15th and 3:10 AM on the 17th, respectivelyi, both located 8 miles west of Tom's Place. A M=1.4 earthquake at 3:51 AM on the 17th was located beneath the west shore of Crowley Lake along the southern margin of the caldera.
