Some new research on the Newmark Displacement Method for earthquake-induced landslides indicates that the method may be on the unconservative side. The Landslide Blog provides a short summary of the paper by Li et al. (2018) that was recently published in the journal Landslides. Their research was based on physical models on a shake table, comparing the results of the model experiments with a Newmark analysis. The paper should be worth a read for geotechnical engineers practicing in seismically active areas. It sounds like some additional study is needed to confirm these results and if they are true, propose different ways of analyzing earthquake-induced landslides.

Wal-Mart Sues over 2006 Kilbuck Landslide
In case you missed the background on the Kilbuck Landslide (or here or here), it happened in Kilbuck Township, PA back in in September of 2006. To deal with the political hot potato and media nightmare, Wal-Mart bought out the developer on the unfinished property and began handling remediation of the slide itself. Now, it appears as if they want their money back from the developer! Read on for more details.
