The 1915 Pleasant Valley earthquake occurred at 22:53:21 on October 2 in north-central Nevada. 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. The rupture originated along an unnamed fault somewhere in the eastern side of Pleasant Valley
The earthquake’s damage was confined to within 50 miles (80 km) 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
