Abstract：Earthquakes and landslides are two major geological disasters causing huge casualties and economic losses each year across the world. Both landslides and earthquakes can be shown in a model of double blocks separated by a sliding plane. The key for geo-disaster prediction is the Newton force variation along the sliding plane. However，the measurement of the Newton force on the sliding plane is extremely difficult. Therefore，most of the current researches on earthquakes and landslides rely on the displacement monitoring between the two blocks. The relative displacement between the two blocks is considered as the necessary condition but not the sufficient condition for the occurrence of the earthquake and/or landslide，which may be the reason for the general recognition of the limitation on geo-disaster prediction. The presentation introduced a study on the theory of double-block mechanics(DBM) including the measurement of the Newton force，which is the necessary and sufficient conditions for initiating a geological disaster due to the block motion，using the so-called constant- resistance and large-deformation cable with negative Poisson?s ratio effect. Applications for geo-disaster prediction were also described in this presentation.
