The work was motivated by the high incidence of lightning in the disaster occurred in the mountainous region of the State of Rio de Janeiro in 2011. In the episode was recorded more than 900 deaths and up to the present time, the causes of landslides have not been fully met. This research presents the development of a physical model to assess the effects of sound waves coming from the thunder in soils. To achieve the above goal, we developed a camera to which an undisturbed block of soil, instrumented with tensiometers and TDR s accelerometers was tested on a table. The materials used in the tests are from hillside located in the areas of PUC-Rio and condo located in the Conquista, Nova Friburgo. Soils were willing blocks free or confined in a box of 19mm plywood and then were subjected to the sound waves replicated modeling of thunder. The results include the development of assays with different humidities for both types of materials and conditions, free and confined.
