NASA scientists are building an open global inventory of landslides with the goal of improving predictive models for landslides. The data is crowd-sourced and some are scraped from news sources as well. Anyone can download the data in various formats as well as their open-source predictive model. The model relies on an initial landslide susceptibility analysis and depending on the susceptibility, satelite-based estimates of rainfall are used to issue a moderate- or high-hazard “nowcast”.

A report has been released by the NYSDOT on the Scoby Hill Landslide which has impacted a 4.2-mi improvement project of Route 219. The report, dated May 20, 2008 was headed to an FHWA peer review panel.
The Feds were call in to help because of the unusual nature of the landslide. The slip surface is very deep, approximately 30-m (100-ft) below the surface and below all of the design phase investigations. And the remolded shear strength of the silty clay forming the slip surface was only 12-14 degrees.

ODOT’s I-5: Iowa Street Viaduct Replacement Project in Portland will reportedly cut into 6 ancient landslide surfaces according to a PSU Geology Professor. The existing bridge structure is over 50-years old and deteriorating and will […]
