Abstract
To gain an insight into earthquake slip weakening due to thermal pressurization, microscopic molecular structures associated with water desorption are investigated for layered-hectorite nanoparticles by positronium (Ps) annihilation spectroscopy, thermogravimetry and differential thermal analysis (TG–DTA) and time-resolved length-change measurement with high resolution dilatometry. The large macroscopic length change of ~ 6% occurs simultaneously with the formation of open spaces with the size of ~ 7 Å when water molecules are desorbed from the interlayer spaces.
