TL;DR: In this paper, in-situ velocity measurements were used to identify different lithologies beneath surficial talus deposits, and the thickness of these talus blocks, of about 4-30 m, found by seismic refraction, clearly demonstrates that huge blocks within the talus/debris are in close contact with the basement.

TL;DR: In this article, an assessment of climate change consequences for displacement rates of a mudslide in the Dolomites, Italy, is presented based on climate projections of a general circulation model (GCM).

TL;DR: A data set of 47 earthquake-induced landslides occurring in Greece from AD 1650 to 1995 has been compiled, and the landslide distribution has been examined as mentioned in this paper, and the upper bound of the maximum epicentral distance, R e, from a reported landslide has been approximated by the line log(R e )='2.98+0.75M s for M s µ5.3, which is compatible with curves proposed world-wide and constitutes a realistic solution at least for hazard assessment purposes.

TL;DR: In this paper, the authors discuss the performance of the borehole wire extensometer and the interpretation of its results for the case of a translational slide and show that the displacements measured with the wire extENSometer are systematically smaller than the movements observed at the ground surface.

TL;DR: In this article, a method for estimating the in situ stress state by analyzing microseismic clusters induced by hydraulic injections is proposed, which is based on focal mechanism analysis, supplemented with microseismsic doublet analysis, and is used to discriminate between the fault plane and the auxiliary planes of the focal mechanism solution.

TL;DR: In this paper, the authors present the distinct characteristics of Typhoon Herb as well as the induced hazards, including their extraordinary size and recurrent nature, and a comparison of hazards in other countries is also made and the results indicate that the extremely heavy rainfall encountered and the existence of a boundary fault in Taiwan are the most susceptible factors inducing the extraordinary hazards.
