The impoundment of the 660-km long reservoir behind huge Three Gorges Dam, world's largest hydropower station, increased regional seismicity and reactivated severe geohazards. Before filling was initiated in 2003, region had approximately two earthquakes per year with magnitudes between 3.0 4.9; after full 2008, 14 occurred 5.4. In addition, hundreds landslides were are now a state intermittent creep. Many exhibit step-like annual pattern displacement response to quasi-regular variations...
Mountainous regions are inherently susceptible to geohazards, such as landslides and debris flows, with the threat of natural disasters compounded by human activities (mainly settlements). Lessons learned from past events that involved interactions between geohazards helpful for future site selections settlements in mountainous regions. To this end, associated county seat relocations Badong, a typical Three Gorges Reservoir region, China, studied an engineering geologist's perspective. Over...
A four year‐long accelerometric monitoring of a landslide‐prone slope area in Italy provided evidence amplifications with systematic directional differences shaking energy by factor 2–3, apparently correlated the directions local topographic features. The examination regional‐scale data revealed similar site response directivity phenomena also on some steep rock slopes not affected amplification. spectral properties responses were investigated using HVSR analysis and new approach based...
Abstract. Recent observations have shown that slope response to seismic shaking can be characterised by directional variations of a factor 2–3 or larger, with maxima oriented along local topography features (e.g. maximum direction). This phenomenon appears influenced material properties and has occasionally been detected on landslide-prone slopes, where down-slope directed amplification could enhance susceptibility seismically-induced landsliding. The exact conditions for the occurrence...
Abstract. We report on new developments in the application of ambient noise analysis applied to investigate dynamic response landslide-prone slopes seismic shaking, with special attention directional resonance phenomena recognised previous studies. These can be relevant for slope susceptibility, especially when maximum orientation is close potential sliding directions. Therefore, implementation an effective technique site directivity detection general interest. In this regard methods based...

Abstract The historical variations in landslide activity are investigated the Rocchetta S. Antonio territory, where sown fields cover 75% of total area. perception inhabitants is that landsliding has increased recent years, and climate change been invoked as a case. However, since 1865 annual precipitation decreased c . 8% per century southeastern Italy local rainfall data for 1955–2008 period show high inter-annual variability with statistically uncertain trends. In same decades human...
