TLDR
Although analysis after the storms suggests that modifications and additional development are needed, the system successfully predicted the times of major landslide events and could be used as a prototype for systems in other landslide-prone regions.Abstract:
A real-time system for issuing warnings of landslides during major storms is being developed for the San Francisco Bay region, California. The system is based on empirical and theoretical relations between rainfall and landslide initiation, geologic determination of areas susceptible to landslides, real-time monitoring of a regional network of telemetering rain gages, and National Weather Service precipitation forecasts. This system was used to issue warnings during the storms of 12 to 21 February 1986, which produced 800 millimeters of rainfall in the region. Although analysis after the storms suggests that modifications and additional development are needed, the system successfully predicted the times of major landslide events. It could be used as a prototype for systems in other landslide-prone regions.read more

The rainfall intensity–duration control of shallow landslides and debris flows: an update
TL;DR: In this article, a global database of 2,626 rainfall events that have resulted in shallow landslides and debris flows was compiled through a thorough literature search, and the rainfall and landslide information was used to update the dependency of the minimum level of rainfall duration and intensity likely to result in shallow landslide and debris flow established by Nel Caine in 1980.

A warning system for rainfall-induced shallow failures
TL;DR: In this article, the authors identified the empirical triggering thresholds for the Piedmont Region Four meteoric events were selected and analysed (November 4-5-1994, July 7-8-1996, April 27-30-2000, and October 13-16-2000) and the triggering threshold is given by the expression: NI=−009ln[NCR]+054 (where NCR is the normalised cumulative critical rainfall, [mm/PMA]×100) In detail an operating procedure which is presently being verified and tested in the studied area is described

The Rainfall Intensity - Duration Control of Shallow Landslides and Debris Flows
TL;DR: In this article, rainfall intensities and durations associated with shallow landsliding and debris flow activity suggests a limiting threshold for this type of slope instability, and the limit is defined based on the rainfall intensity and duration.
