Elaine is dealing with 100 degree F heat, low humidity, and a fire in the Reno area. She has been spared in her Golden Valley home.
Elaine has a number of stories on the Ridgecrest, CA, earthquake. Below are some pictures that were sent around on Twitter by geologist Brian Olson and retweeted by my OSU collegaue Adam Kent. Text below is from Olson's Tweet.
Nice examples of vertical & horizontal offsets caused by the Ridgecrest earthquake. 1st picture is 3.75-foot high scarp, 2nd picture is fault rupture across the China Lake salt flat, 3rd picture is aerial view of stream channels moved sideways.
