Description:

A surface wave field-testing campaign was conducted at the Drainage Farm Site in Logan, Utah, USA, a property owned by Utah State University (USU). The field testing involved both active-source multichannel analysis of surface waves (MASW) testing and ambient noise (microtremor array measurements: MAM) testing. Structural geology indicates that Southern Cache Valley, encompassing the Drainage Farm Site and located in the northeastern part of the Basin and Range province, is a graben bounded by high-angle normal faults (Williams, 1962). The site is underlain by Paleozoic rocks, which are overlain by Tertiary formations such as the Wasatch and Salt Lake formations, composed of conglomerate, siltstone, and tuffaceous sandstone. In certain areas of Cache Valley, these formations reach thicknesses of up to 2,440 m (Evans et al., 1996). The near-surface geology of the Drainage Farm Site is characterized by sediments from ancient Lake Bonneville, which receded to form the Provo shoreline. These sediments include alluvial, lacustrine, and deltaic deposits (Williams, 1962; Evans et al., 1996). Well logs presented by Williams (1962) reveal alternating layers of silt and clay, sand, and gravel above the Salt Lake formation. Moreover, limited deep well logs from the vicinity of the Drainage Farm Site indicate that rock can be encountered at depths ranging from 176 m to more than 350 m (Perez, 1969).
