On 22 January 2003, the Mw = 7.6 Tecomán earthquake struck offshore of the state of Colima, Mexico, near the diffuse triple junction between the Cocos, Rivera, and North American plates. Three-hundred and fifty aftershocks of the Tecomán earthquake with magnitudes between 2.6 and 5.8, each recorded by at least 7 stations, are relocated using the double difference method. Initial locations are d...

The recurrence intervals of repeating earthquakes on the San Andreas Fault in the Loma Prieta aftershock zone follow the characteristic 1/t decay of Omori’s law. A model in which these earthquakes occur on isolated patches of the fault that fail in stick-slip with creep around them can explain this observation. In this model the recurrence interval is inversely proportional to the loading rate ...

steady hydromagnetic couette flow of class-ii of a viscous, incompressible and electrically conducting fluid through a porous medium in a rotating system taking hall current into account is investigated. heat transfer characteristics of the fluid flow are considered taking viscous and joule dissipations into account. it is noticed that there exists flow separation at the moving plate in the sec...

SUMMARY The Sarria-Triacastela-Becerreá seismicity is located in an intraplate region considered seismically stable, but 1995 started unprecedented earthquake activity the area. Since then anomalous long-term continuous remains until now same location. Despite and large magnitudes for standards (5.1 Mw), origin mechanisms of this unclear. isolation background from main shock–aftershock contribu...

investigation of velocity structure based on seismic wave propagation have been performed in recent years in different parts of iran that results obtained is effective in the analysis of seismic zones and locate earthquakes with reasonable accuracy. on a broad scale, the seismotectonics of southern iran are controlled by active convergence between the arabian and eurasian tectonic plates that a...

 In the present paper damped vibrations of non-homogeneous infinite rectangular plate of parabolically varying thickness resting on elastic foundation has been studied. Following Lévy approach, the equation of motion of plate of varying thickness in one direction is solved by quintic spline method. The effect of damping, elastic foundation and taperness is discussed with permissible range of pa...
