Шаблон:Infobox earthquake

The 1915 Pleasant Valley earthquake occurred at Шаблон:Tooltip in north-central Nevada. With a moment magnitude of 6.8, a surface wave magnitude of 7.7, 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 fault scarps along the west side of the Tobin Range. It produced four scarps, with a total length of Шаблон:Convert, and re-ruptured Holocene scarps located at the bottom of the base of the mountain blocks.[1] Among the scarps, the average vertical displacement among the affected areas was Шаблон:Convert, and the maximum displacement of Шаблон:Convert occurred near the old Pierce School site on Buskee Creek Canyon.[2][3]

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.[2]

Damage

The earthquake's damage was confined to within Шаблон:Convert of the epicenter. Damage in Kennedy destroyed two adobe houses, collapsed several mine tunnels, and cracked concrete mine foundations. Winnemucca experienced damage to adobe buildings as well, and several multistory brick buildings lost coping and upper wall parts. Many chimneys were destroyed if they were above roof lines. Water tanks were knocked over in Battle Mountain, Kodiak, Lovelock, and Parran. Several ranches reported damage, all by the southern end of Pleasant Valley. More adobe houses were knocked down by the shaking; a masonry chicken house and a hog pen were destroyed; and houses were displaced from their foundations.[4]

Aftershocks

The earthquake had several aftershocks which disturbed a significant amount of land in Northern Nevada.[5]
