The present status of research and understanding regarding the dynamics and the statistical properties of earthquakes is reviewed, mainly from a statistical physical view point. Emphasis is put both on the physics of friction and fracture, which provides a microscopic basis for our understanding of an earthquake instability, and on the statistical physical modelling of earthquakes, which provides macroscopic aspects of such phenomena. Recent numerical results from several representative models… 
Statistical physics of fracture and earthquakes
Some aspects of collective response of a long-ranged correlated multi-component system in widely spread length and energy scales are treated from various angles of experiments, simulations and analytical methods, and connected together by their common base of complex-system dynamics.
Mechanical origin of aftershocks
This study shows that the size of the aftershock zone depends on the fault geometry, and finds that positive correlations among parameters controlling aftershock occurrence in time, energy and space are a stable feature of seismicity independently of magnitude range and geographic areas.
Earthquake sensitivity to tides and seasons: theoretical studies
We investigate theoretically the effects of periodic-in-time modulations on the properties of earthquakes. To wit, we consider successively the one dimensional Burridge–Knopoff (BK) model and the two
A Description of Seismicity Based on Non-extensive Statistical Physics: A Review
Earthquakes have always been one the most intriguing natural phenomena for mankind. The abruptness of the shaking ground and the devastating consequences for the human environment were always
Story of the Developments in Statistical Physics of Fracture, Breakdown \& Earthquake: A Personal Account
We review the developments of the statistical physics of fracture and earthquake over the last four decades. We argue that major progress has been made in this field and that the key concepts should
Power-law rheology controls aftershock triggering and decay
It is shown that nonlinear viscoelasticity plays a critical role in the occurrence of aftershocks, and the proposed model reproduces several empirical laws describing the statistics ofaftershocks.

Numerical simulations were performed to examine the effects of heterogeneity of frictional properties on earthquake cycles. In the model, rate- and state-dependent friction was assumed at a planar


Friction, Fracture, and Earthquakes
A primary goal in seismology is to identify constraints arising from the small-scale physics of friction and fracture that can provide bounds on seismic hazard and ground motion at the fault scale.
Statistical physics approach to understanding the multiscale dynamics of earthquake fault systems
[1] Earthquakes and the faults upon which they occur interact over a wide range of spatial and temporal scales. In addition, many aspects of regional seismicity appear to be stochastic both in space
Rate-and state-dependent friction law and statistical properties of earthquakes
In order to clarify how the statistical properties of earthquakes depend on the constitutive law characterizing the stick-slip dynamics, we make an extensive numerical simulation of the

This work examines the dynamic behavior of a simple mechanical model of an earthquake fault that retains the full Newtonian dynamics with inertial effects and contains no externally imposed stochasticity or spatial inhomogeneity.
Dynamics of earthquake faults
The authors present an overview of ongoing studies of the rich dynamical behavior of the uniform, deterministic Burridge-Knopoff model of an earthquake fault, discussing the model's behavior in the
A dissipation-based analysis of an earthquake fault model
We analyze the dynamics of a discrete dynamical model of earthquake faulting, derived from the Burridge-Knopoff model. The system is shown to exhibit a characteristic event size (L* = 2v2f l2) that
A fractal model of earthquake occurrence: Theory, simulations and comparisons with the aftershock data
Our understanding of earthquakes is based on the theory of plate tectonics. Earthquake dynamics is the study of the interactions of plates (solid disjoint parts of the lithosphere) which produce
Properties of earthquakes generated by fault dynamics.
A model for fault dynamics consisting of a uniform chain of blocks and springs pulled slowly across a rough surface finds that this model gives rise to events of all sizes and results in power-law spectrum similar to what is observed in nature.
Numerical simulation of recurrence of asperity rupture in the Sanriku region, northeastern Japan
[1] A numerical simulation study is presented for the recurrence of great earthquakes and aseismic sliding in the Sanriku region, northeastern Japan, where the Pacific Plate subducts beneath northern
