although there is enough knowledge indicating on the influence of frequency content of input motion on the deformation demand of structures, state-of-the-practice seismic studies use the intensity measures such as peak ground acceleration (pga) which are not frequency dependent. the v max/a max ratio of strong ground motions can be used in seismic hazard studies as the representative of frequen...

Detailed seismic investigation of an unusually intense earthquake swarm which occurred in the northern Gulf of California during March 1969 has provided new information about seismic processes which occur on actively spreading oceanic ridges and has placed some constraints on the elastic wave velocities beneath them. Activity during this swarm was similar to that of a foreshock-mainshock-afters...

This work investigates the effect of the explicit inclusion of queueing delays due to locking overhead in a performance study of a two phase locking concurrency control method. A mean value analysis is used to calculate the system's performance measures, response time and throughput. It is found that the locking overhead's contribution to delay depends largely on the degree of page faulting act...

This article presents equations for the estimation of horizontal strong ground motions caused by shallow crustal earthquakes with magnitudes Mw ≥ 5 and distance to the surface projection of the fault less than 100 km. These equations were derived by weighted regression analysis, used to remove observed magnitude-dependent variance, on a set of 595 strong-motion records recorded in Europe and th...

Over the past few decades, earthquake engineering research mainly focused on the effects of strong seismic shaking. After the 1999 earthquakes in Turkey and Taiwan, and thanks to numerous cases where fault rupture caused substantial damage to structures, the importance of faulting-induced deformation has re-emerged. This paper, along with its companion (Part II), exploits parametric results of ...

Incision of the Colorado River in the Grand Canyon, widely thought to have happened between ca. 6 and 1.2 Ma, has continued at variable rates along the canyon over the past ;500 k.y., based on measurements of bedrock incision combined with U-series and 40Ar/ 39Ar ages. River incision rates downstream of the Toroweap fault in the western Grand Canyon are about half the ;140 m/m.y. incision rate ...
