[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 and time. However, within this complexity, there is considerable self-organization. We argue that the occurrence of earthquakes is a problem that can be attacked using the fundamentals of statistica...

The possibility that the Earth’s tides are a triggering factor of Vrancea subcrustal earthquakes is investigated in the first part of this paper. A possible correlation between Vrancea subcrustal earthquakes and geomagnetic jerks is demonstrated in the second part. The last part of the paper presents a number of results concerning a possible relationship between the regularities of strong Vranc...

China is a country of intense intracontinental seismicity. Most earthquakes in western China occur within the diffuse Indo-Eurasian plate-boundary zone, which extends thousands of kilometers into Asia. Earthquakes in eastern China mainly occur within the North China block, which is part of the Archean Sino-Korean craton that has been thermally rejuvenated since late Mesozoic. Here, we summarize...

according to iranian code of practice for seismic resistant design of buildings standard no. 2800, yazd is located in the place with the medium earthquake hazard [1]. due to the position of yazd with many historical and important buildings, maintaining these traditional heritages is an important task in civil engineering field. on account of these mentioned valuable buildings and region potenti...

Title: A Preliminary Study on the Relation Between Polar Wandering and Seismicity

This article explores the problem of short-term earthquake prediction based on spatio-temporal variations of seismicity. Previous approaches to this problem have used precursory seismicity patterns that precede large earthquakes with "intermediate" lead times of years. Examples include increases of earthquake correlation range and increases of seismic activity. Here, we look for a renormalizati...

We investigate on the capability of the strongest earthquakes to modify significantly the seismicity in a wide spatio-temporal window. In particular, we show that the strongest earthquakes of last century were probably able to influence the seismicity at large spatio-temporal distances, extending their reach over thousand of kilometers and decades later. We report statistically significant diff...

We describe a model to estimate event rates of a non-homogeneous spatio-temporal Poisson process. A Bayesian change point model is described to detect changes in temporal rates. The model is used to estimate whether a change in event rates occurred for a process at a given location, the time of change, and the event rates before and after the change. To estimate spatially varying rates, the spa...

We study deep aseismic slip along the central section of the San Jacinto Fault, near the Anza Seismic Gap, in southern California. Elevated strain-rates following the remote Mw7.2 April 4, 2010 El Mayor-Cucapah and the local Mw5.4, July 7, 2010 Collins Valley earthquakes were recorded by Plate Boundary Observatory borehole strain-meters near Anza, and were accompanied by vigorous aftershock seq...

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...
