The 1934 Hansel Valley earthquake occurred on March 12 at approximately 8:05 a.m. MST with a moment magnitude of 6.6 and a maximum Mercalli intensity of VIII (Severe).
The shock originated in the Hansel Valley at the north end of the Great Salt Lake in Utah in the United States.
[1] Within the ISB, the Basin and Range Province is a region of extensional tectonics and lays between the Sierra Nevada in the west and the Colorado Plateau in the east.
[6] The mainshock is depicted by a United States Geological Survey isoseismal map with a relatively small zone with the maximum felt intensity of VIII (Severe) at the north end of the Great Salt Lake.
Cracked walls and damage to chimneys was reported in Logan, Hooper, Kelton, Kosmo, Locomotive Springs, Monument, and Snowville.
[5] Following a 20th-century field survey of the affected areas, features such as large rock slides, previously dormant wells and springs, and an increase in the flow of an oil seep were documented.
The surveyor reported that in areas where surface faulting was present, it was discontinuous and it did not occur in bedrock and was mostly observed in unconsolidated rocks or salt flats.
