With a moment magnitude of 6.8 and a maximum Mercalli intensity of X (''Extreme''), it was the strongest earthquake ever recorded in the state. ==Earthquake== The earthquake remains as one of the best examples ever for evidence of creating spectacular fault scarps along the west side of the Tobin Range. It produced four scarps, with a total length of , and re-ruptured Holocene scarps located at the bottom of the base of the mountain blocks. Among the scarps, the average vertical displacement among the affected areas was , and the maximum displacement of occurred near the old Pierce School site on Buskee Creek Canyon.〔〔Mt. Tobin, Nev 15 minute topographic quadrangle, 1961, USGS〕 The rupture originated along an unnamed fault somewhere in the eastern side of Pleasant Valley, in north-central Nevada. The epicentral region was mostly uninhabited, so there was little property damage considering the very large magnitude. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「1915 Pleasant Valley earthquake」の詳細全文を読む スポンサード リンク
