A model for rock dissipated energy estimation based on acoustic emission measurements
Frontiers in Earth Science, 2023 The temporal domain of dissipated energy during rock damage and failure is commonly quantified using loading and unloading tests or elastic mechanics-based theoretical calculation methods. However, these approaches cannot be applied to obtain the spatial

Fractal Seismicity and Seismic Risk [PDF]
Izvestiya, Physics of the Solid Earth, 2020 Recently, attempts have been made to take into account the fractal properties of seismicity when mapping the long-term rate of earthquakes. The paper touches upon the theoretical aspects of fractality and provides a critical analysis of its applications to the problems of seismic ...
