Field observations were conducted by traversing the entire extent of the path of both landslides on foot. The Eagle Pass ground investigation was supported by a helicopter. Measurements of the dimensions...

... of giant landslide blocks in the middle of Lake Tahoe revealed that the sampled blocks consist of poorly lithified lacustrine sediment closely resembling the type that underlies the Tahoe City shelf ( Moore et al., 2006 ). Prior to landsliding, the shelf extended south of Eagle Rock, but landsliding...

... ). One possibility is monitoring landslides, volcanoes, and earthquake faults. For instance, minor displacements commonly generate cracks in advance of landslide events that would result in velocity decreases and attenuation increases, dynamic phenomena to which the PASS is sensitive. The PASS could also...

... unconsolidated soils (i.e., loosely arranged, lacking strong bonds) and clays caused slumping, landslides, liquefaction, and in some more notorious cases the complete sloughing of steep bluffs. The reconstruction in the decade following the 1964 earthquake coincided with a boom in Alaska development tied...

... ). To resolve these ambiguities, constraints on extension across the central Death Valley region, and across other extended terranes in the Basin and Range, have been developed through the identification of late Cenozoic sedimentary rocks, such as alluvial fan conglomerates or landslides, that were deposited...

Five minor low-angle faults are exposed in the central Grant Range—one in the north (Blue Eagle thrust), two in Beaty Canyon, one...

..., lies between the deformation front and the conglomerate unit, locally coinciding with its upper contact. The frontal fault passes through Eagle Harbor, near the northern limit of uplift associated with the M 7 earthquake ∼1100 yr ago ( a.d. 900–930) ( Bucknam et al., 1992 ). The Blakely Harbor fault...

For example, to the south near La Veta Pass (LVP in Figure 5a ) and to the north toward the Eagle basin ( Figure 5a ), the Minturn Formation...

However, northeast projection of a regional northeast-trending fault shown by Foster (1976) , part of the Mount Harper lineament of Wilson et al.

Many of the larger landslides occurred on faults with surface ruptures that passed through their source areas (Fig.  3 ). Interestingly, the larger landslides, while...

The state government responded within one month by passing the Field Act, which mandated earthquake-resistant school design by licensed professionals, plan review, and continuous inspection during construction ( CSSC, 2007 ; Perkins et al., 2006 ).
