1893. March 30; Independence and Lone Pine, Inyo County. 



Mr. C. Mulholland reijorts: " On the evening of last Thursday, 

 March 30, at 10.30 o'clock, an earthquake occurred. The center 

 of disturbance appeared to be about 9 miles north from the 

 south end of Owens Lake. At that point there is a strip of land 

 2 miles wide between the lake and the base of the Sierra Nevada 

 on the west. But one shock was felt; this was very sharp; the 

 earth motion may be likened to the result of a blow struck upon 

 a plank by a sledge. At Lone Pine, 30 miles farther north, the 

 shock was felt about the same time; the vibration was not so 

 sharp, but more undulatory. No damage." — Carson, March 30, 

 during the night, N. E. and S. W., tremor, from seismometer. — 

 C. W. F.
