National landslide hazards mitigation strategy : a framework for loss reduction

Abstract

House Report 106-222 accompanying the Interior Appropriations Bill for fiscal year 2000 (as incorporated in Public Law 106-113) states, "The committee is concerned over the lack of attention given to the Survey's landslide program. Because of this concern, the Survey is directed to develop by September 15, 2000, a comprehensive strategy, including the estimated costs associated with addressing the widespread landslide hazards facing the Nation. The preparation of this strategy should include the involvement of all parties having responsibility for dealing with the problems associated with landslides." In fulfillment of the requirements of Public Law 106-113, the United States Geological Survey submits this circular, which describes a national strategy to reduce losses from landslides. The circular includes a summary of the Nation's needs for research, monitoring, mapping, and assessment of landslide hazards nationwide.

Rainfall-triggered landslides, anthropogenic hazards, and mitigation strategies

“…This issue is common in much of the developing world as well (O'Hare and Rivas, 2005). Communities can reduce their exposure to landslide hazard if they understand the threat, its potential impact, and their mitigation options (Spiker and Gori, 2000).…”

iCRESTRIGRS: a coupled modeling system for cascading flood–landslide disaster forecasting

“…This model links analytical solutions for transient, unsaturated, vertical infiltration above the water table (Srivastava and Yeh, 1991) to pressure-diffusion solutions for pressure changes below the water table. The solutions are linked through a transient water table that rises as water accumulates at the base of the unsaturated zone.…”

“…Flooding causes property losses of USD 3.7 billion and approximately 110 fatalities per year nationwide (Ashley and Ashley, 2008), while landslides are responsible for 25-50 deaths and damage exceeding USD 2 billion annually (Spiker and Gori, 2003). Shallow landslides induced by heavy rainfall have posed significant threats to human lives and property worldwide (Hong et al, 2006;Kirschbaum et al, 2010).…”

Electrostatic precursors to granular slip events

“…On the large scale, these transitions manifest themselves in catastrophic geological slip events (2)(3)(4), and on the small scale, they are intimately associated with fracture (5) and material inhomogeneities (6,7) , causing a documented 50% rejection rate of manufactured ceramics (8,9). In this letter, we show for the first time that electrical precursors are strongly correlated with-and often precede-any outward sign of a slip event in a powder bed.…”
