One of the most widespread spring-block earthquake models, the Olami-Feder-Christensen model, is investigated without making the assumption that the duration of individual earthquakes is negligible. While the GutenbergRichter law for the size distribution of earthquakes is preserved qualitatively for earthquakes of finite duration, the bvalue decreases with increasing earthquake duration. The e...

Power-law distributions of landslides and rockfalls observed under various conditions suggest a relationship of mass movements to self-organized criticality (SOC). The exponents of the distributions show a considerable variability, but neither a unique correlation to the geological or climatic situation nor to the triggering mechanism has been found. Comparing the observed size distributions wi...

abstract when in administrative law the matter of administrative offences are raised, these offences would have legal nature if they are force able, some of these offences are related to administrative law, where as some other pelts are common in civil or penal law. the current research intends not only to consider the concept and foundation of administrative execution rules but also compares...

We analyzed the historical seismicity in southern California to develop a rational approach for calculating the seismic hazard from background seismicity of magnitude 6.5 or smaller. The basic assumption for the approach is that future earthquakes will be clustered spatially near locations of historical mainshocks of magnitudes equal to or greater than 4. We analyzed the declustered California ...

what has been discussed here has been a study of international immigration law. this branch of law has not been a major player in the field of international law. no collective law exists, and no codification has been carried out as yet. however, the need for such a set of laws has forced the international community to pay more attention to this issue. the need for a better life in the so-call...

in the name of allah , the compassionate the merciful abstract shath ( blasphemic utterace made during spiritual ) is a complicated concept that deserves reflection in gnosticism and sufism ( mysticism ) and estem and westem scholars have alwaya paid attention to it. although principal essence of gnostic belief is the holy divine law ,gnosticism has pure and unique thoughts . by glancing at t...

S U M M A R Y I n order to understand the underlying physics of distributed seismicity better we have considered a 2-D array of slider blocks connected by springs and interacting via static friction with a surface. There is no driving plate in this model. The time evolution of the system is found from numerical simulations in a cellular automata formulation. Energy is conserved and is the singl...
