Historically, seismicity documented in the Western Canada Sedimentary Basin has been relatively quiescent and earthquakes are usually restricted to the foreland belt of the Rocky Mountains. However, exceptional clusters of events, which have remained active for decades, are recognized in Alberta. In this study we investigate the seismicity in this region using data obtained from recently establ...

[1] We establish a connection between geometry of the faults’ network in a region and seismicity preceding the strong earthquakes in the intermediate-term timescale of years. Previous studies of observed and computer-simulated seismicity demonstrated that strong earthquakes are preceded in that timescale by the rise of seismic activity in a lower magnitude range. Here, we explore a complementar...

the central alborz mountains of northern iran (figure 1) is a zone of intense active continental deformation and is the most heavily populated region of iran, including the mega-city of tehran with a population of over 10 million. the region is affected by numerous active faults, some of them having great seismic potential, and documented historical seismicity. hence, the central alborz is a pr...

This paper is about short review of earthquake statistics and efforts for earthquake mitigation, hazard and risk assessment studies in Pakistan. Pakistan and adjoining region lying between longitude 60 ̊E to 78 ̊E and latitude 20 ̊N to 45 ̊N are selected for the study as this region has a history of many large earthquakes because of its location in the region of intersection of three plates namely ...

[1] The great earthquake sequence that occurred in the central Mississippi River Valley during the winter of 1811– 1812 is unprecedented in the historical record of seismicity within stable continental plate interiors. We show, using viscous flow models based on high resolution seismic tomography, that the descent of the ancient Farallon slab into the deep mantle beneath central North America i...

In this research seismicity parameters, repeat times and occurrence probability of large earthquakes are estimated for 35 seismic lineaments in Persian plateau and the surrounding area. 628 earthquakes of historical time and present century with MW>5.5 were used for further data analysis. A probabilistic model is used for forecasting future large earthquake occurrences in each chosen lineament....
