That Yosemite swarm got a fresh boost the last couple of days. The following
earthquakes were observed:

MAG YEAR MO DA TIME PDT LAT LONG DEPTH LOCATION

ML=2.1 2001/05/23 11:29:55 37.650N 119.408W 2.5 ESE of Yosemite Village, CA
ML=1.7 2001/05/23 11:25:04 37.655N 119.411W 6.4 ESE of Yosemite Village, CA
ML=1.8 2001/05/23 11:53:21 37.665N 119.498W 5.0 SE of Yosemite Village, CA
ML=2.2 2001/05/21 19:53:25 37.647N 119.412W 0.8 SE of Yosemite Village, CA

I wonder if we will see something in Mammoth Lakes slight to the
east of here shortly like we did on the 21st.

But the big news is the Ml 3.8 in the San Gorgonio CA region a few
minutes ago.

ML=3.8 2001/05/23 12:10:34 34.020N 116.755W 14.1 SE of Mt. San Gorgonio, CA
