Eastern Idaho: 1975


Mar. 28, 1975. Eastern Idaho.

In the Ridgedale area of the sparsely populated Pocatello Valley, this earthquake shifted several ranch houses on their foundations and toppled many chimneys.

At Malad City, 20 km northeast of the epicenter, about 40 percent of the chimneys on old buildings were damaged.

Total property damage was estimated at $1 million.

Geologists observed one zone of ground fractures - about 0.6 km long and 5 cm wide - in the south-central section of the valley.
