The quake hit at 2:35 in the morning and leveled almost all the buildings in Lone Pine and nearby settlements. Of the estimated 250-300 inhabitants of Lone Pine, 27 are known to have perished and 52 of the 59 houses were destroyed. One report states that the main buildings were thrown down in almost every town in Inyo County. About 100 kilometers south of Lone Pine, at Indian Wells, California, adobe houses sustained cracks. Property loss has been estimated at $250,000 (1872 dollars). As in many earthquakes, adobe, stone and masonry structures fared worse than wooden ones which prompted the closing of nearby Camp Independence which was an adobe structure destroyed in the quake.
The quake resulted from sudden vertical (15-20 feet) and right-lateral (35-40 feet) movement on the Lone Pine fault and part of the Owens Valley fault. These faults are part of a twin system of normal faults that run along the base of two parallel mountain ranges; the Sierra Nevada on the west and Inyo Mountains on the east flank of Owens Valley. This particular event created fault scarps from north of Big Pine, California (55 miles north of Lone Pine), to Haiwee Reservoir (30 miles south of Lone Pine).
Researchers later estimated that similar earthquakes occur on the Lone Pine fault every 3,000-4,000 years. However, the Lone Pine fault is only one of many faults on two parallel systems of faults mentioned above.
This earthquake also reportedly formed a small graben that later was filled by Diaz Lake.
Many geoscientists who have studied the area, theorize that quakes similar to the 1872 Lone Pine event, are responsible for creating Owens Valley (see Basin and Range Province for ideas on what triggers these quakes).
