Short-period body waves recorded at teleseismic distances from great earth· quakes provide information about source rupture processes and strong motions. First, we examine mostly WWSSN records of 19 earthquakes of moment magni· tude Mw of 6.5 to 9.5. Four parameters are measured from the short-period Pwave train: the maximum amplitude; the period at maximum amplitude; the time between the first...

The 2014 Ms 6.5 (Mw6.1) Ludian earthquake occurred in the eastern Sichuan-Yunnan border region of western China. This earthquake caused much more severe engineering damage than the usual earthquakes with the same magnitude in China. The National Strong Motion Network obtained large set of ground motion recordings during the earthquake. To investigate the engineering interested characteristics o...

When a specific building is examined and analysed for its architectural merits, it is the visible, superficial aspects, which are considered, for example: aesthetics, function, spatial relationships, and landscape. One of the most important invisible factors that should be considered in the design process is the safety of buildings against natural hazards, particularly against earthquakes. Whil...

Although earthquakes happen frequently in many parts of the world, any occurrence of a moderate to large event is sudden and unexpected. Thus, the earthquake process can be interesting and even frightening to people. Most earthquakes are associated with natural, dynamic processes that shape Earth’s landscape. The vast majority of earthquakes are caused by sudden slip along faults, resulting in ...

S U M M A R Y We perform a comprehensive analysis of dynamic triggering around the Babaoshan and Huangzhuang-Gaoliying faults near Beijing, China. The triggered earthquakes are identified as impulsive seismic arrivals with clearP and S waves in 5 Hz high-pass-filtered three-component velocity seismograms during the passage of large amplitude body and surface waves of large teleseismic earthquak...

[1] We use interferometric synthetic aperture radar, GPS, and teleseismic data to constrain the relative location of coseismic slip from 11 earthquakes on the subduction interface in northern Chile (23 –25 S) between the years 1993 and 2000. We invert body wave waveforms and geodetic data both jointly and separately for the four largest earthquakes during this time period (1993 Mw 6.8; 1995 Mw ...

Using the simple ETAS branching model of seismicity, which assumes that each earthquake can trigger other earthquakes, we quantify the role played by the cascade of triggered seismicity in controlling the rate of aftershock decay as well as the overall level of seismicity in the presence of a constant external seismicity source. We show that, in this model, the fraction of earthquakes in the po...
