The author has produced a newly-designed testing apparatus to study the liquefied failures occurred at a natural granitic mountainous slope. As the result of the experiment with the apparatus, the intact weathered granitic soils have not liquefied. However, the test with the sample removed fine particles has been successful and the partial liquefied failure occurred in the apparatus. From the experiment, the possibility and the danger was confirmed, if the soil in a low density were enough saturated, the pore pressure could suddenly rise before few displacement and little deformation, and then drastically fluidize.
