Deep Underground Science and Engineering, EarlyView.The mechanical characteristics of three different types of sandstones under high stress levels are studied. The degree of fragmentation of specimens increases with the applied stress level. The acoustic emission counting of different types of sandstones presents three stages: weakening, stabilizing, and surging.

Earthquake Engineering &Structural Dynamics, Volume 52, Issue 1, Page 183-203, January 2023., 2023 Abstract Estimates of the earthquake ground motion intensity over a geographical area have multiple uses, that is, emergency management, civil protection and seismic fragility assessment. In particular, with reference to fragility assessment, it is of interest to have estimates of the values of different ground‐motion intensity measures in order to ...

The Non-Organic Theory of the Genesis of Petroleum [PDF]
arXiv, 1996 Recent advances in interdisciplinary fields as diverse as astrophysics, cosmogeophysics, nuclear geology, etc. have led to interesting developments in the non-organic theory of the genesis of petroleum. This theory, which holds that petroleum is of an abiogenic primordial origin, provides an explanation for certain features of petroleum geology that ...
