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 ...

At subduction zones, the deep seismogenic transition from a frictionally locked to steady sliding interface is thought to primarily reflect changes in rheology and fluid pressure and is generally located offshore. The development of fluid pressures within a seismic low-velocity layer (LVL) remains poorly constrained due to the scarcity of dense, continuous onshore-offshore broadband seismic arr...

[1] Duan et al. [2011] recently presented analysis of deformation caused by dynamic and static stress changes on fault zones that have reduced strength and effective elastic moduli relative to the ambient rocks. Low-rigidity fault zones were previously proposed to explain anomalous geodetic signals around major crustal faults in the vicinity of large earthquakes [e.g., Fialko et al., 2002; Fial...

A Bayesian statistics approach is applied in the seismogenic sources of Greece and the surrounding area in order to assess seismic hazard, assuming that the earthquake occurrence follows the Poisson process. The Bayesian approach applied supplies the probability that a certain cut-off magnitude of Ms = 6.0 will be exceeded in time intervals of 10, 20 and 75 years. We also produced graphs which ...

Why many major strike-slip faults known to have had large earthquakes are silent in the interseismic period is a long-standing enigma. One would expect small earthquakes to occur at least at the bottom of the seismogenic zone, where deeper aseismic deformation concentrates loading. We suggest that the absence of such concentrated microseismicity indicates deep rupture past the seismogenic zone ...

Primarily aseismic deformation transients in subduction zones, sometimes associated with tremors and low-frequency earthquakes, are a newly recognized mode of deformation. Stressing in the up-dip seismogenic zone is increased episodically due to down-dip transient slips, and each eventmaymake itmore prone to failure in a large thrust earthquake. It is important for seismic hazard assessment to ...
