Collective behavior of earthquakes and faults: Continuum‐discrete transitions, progressive evolutionary changes, and different dynamic regimes

Y Ben‐Zion - Reviews of Geophysics, 2008 - Wiley Online Library
Crustal deformation patterns are affected by multiscale granulation and healing processes
associated with phase transitions between continuum and discrete states of rocks. The …

The later are often taken as the first quantitative characteristics of complex systems, allowing …

Seismic hazard assessment under complex source size distribution of mining-induced seismicity

S Lasocki, B Orlecka-Sikora - Tectonophysics, 2008 - Elsevier
It is well-documented that a variety of factors controlling the rockmass fracturing process in
mines often results in a complexity of mining event size distribution. In such cases, the …
