1D Seismic Velocity Models for West‐Central and Western Montana

Seismicity in the Challis, Idaho, Region, January 2014–May 2017: Late Aftershocks of the 1983 M s 7.3 Borah Peak Earthquake
Abstract The catastrophic Hebgen Lake earthquake of 18 August 1959 (M W 7.3) led many geoscientists to develop new methods to better understand active tectonics in extensional tectonic regimes that address seismic hazards. The Madison Range fault system and adjacent Hebgen Lake–Red Canyon fault system provide an intermountain-active tectonic analog for regional analyses of extensional crustal deformation. The Madison Range fault system comprises fault zones (~100 km in length) that have multiple salients and embayments marked by preexisting structures exposed in the footwall. Quaternary tectonic activity rates differ along the length of the fault system, with less displacement to the north. Within the Hebgen Lake basin, the 1959 earthquake is the latest slip event in the Hebgen Lake–Red Canyon fault system and southern Madison Range fault system. Geomorphic and paleoseismic investigations indicate previous faulting events on both fault systems. Surficial geologic mapping and historic seismicity support a coseismic structural linkage between the Madison Range and Hebgen Lake–Red Canyon fault systems. On this trip, we will look at Quaternary surface ruptures that characterize prehistoric earthquake magnitudes. The one-day field trip begins and ends in Bozeman, and includes an overview of the active tectonics within the Madison Valley and Hebgen Lake basin, southwestern Montana. We will also review geologic evidence, which includes new geologic maps and geomorphic analyses that demonstrate preexisting structural controls on surface rupture patterns along the Madison Range and Hebgen Lake–Red Canyon fault systems.

The Hebgen Lake Earthquake Area, Montana and Wyoming
Abstract The Hebgen Lake Earthquake Area, in southwestern Montana, extends westward from the east edge of Hebgen Lake through the Madison River Canyon, a narrow, deep gorge cut through the Madison Range, to Missouri Flats, west of the range. Hebgen Lake, about 8 mi (13 km) north of West Yellowstone, Montana, lies at the base of the east flank of the Madison Range directly west of the northwest corner of Yellowstone National Park, Wyoming. The lake is used as a storage reservoir impounded behind Hebgen Dam, an earth-filled structure built by Montana Power Company in 1914. The earthquake area is easily reached from almost any direction by major all-weather surfaced highways (inset map, Fig. 1). The area is accessible from the east through Yellowstone Park’s West Entrance, which leads directly into West Yellowstone; from the south by multi-lane U.S. 20, which also passes through West Yellowstone; from the north via U.S. 191, which threads then arrow, deeply forested and scenic Gallatin Canyon; and from the west via U.S. 287, which passes through Ennis, a ranching center that still retains the flavor of the old west. The West Yellowstone airport also gives access to the area. The Hebgen Lake area is a favorite tourist and reort area. Lodging is available in West Yellowstone and at several motels along the north shore of Hebgen Lake. Excellent campsites, well maintained by the U.S. Forest Service, are along U.S. 191 north of West Yellowstone, and in Madison River Canyon (Montana 287) west of Hebgen Dam. Most services are available throughout the year in West Yellowstone, although many hotels and some restarants close for the winter soon after Labour Day.
