Power laws and distributions with heavy tails are common features of many complex
systems. Examples are the distribution of earthquake magnitudes, solar flare intensities and …

There is striking evidence that the dynamics of the Earth crust is controlled by a wide variety
of mutually dependent mechanisms acting at different spatial and temporal scales. The …

The present status of research and understanding regarding the dynamics and the statistical
properties of earthquakes is reviewed, mainly from a statistical physical viewpoint. Emphasis …

Crystal plasticity is mediated through dislocations, which form knotted configurations in a
complex energy landscape. Once they disentangle and move, they may also be impeded by …

When external stresses in a system—physical, social or virtual—are relieved through
impulsive events, it is natural to focus on the attributes of these avalanches,. However …

Among the most important questions that await an answer in seismology, perhaps one is
whether there is a correlation between the magnitudes of two successive seismic events …

Aftershock occurrence is characterized by scaling behaviors with quite universal exponents.
At the same time, deviations from universality have been proposed as a tool to discriminate …

The universality class of the avalanche behavior in plastically deforming crystalline and
amorphous systems has been commonly discussed, despite the fact that the microscopic …

The seismic gap hypothesis states that fault regions where no large earthquake has recently
occurred, are more prone than others to host the next large earthquake. It can lead to the …

This paper is devoted to a phenomenological study of the earthquakes in central Alborz,
Iran. Using three observational quantities, namely the weight function, the quality factor, and …
