A classification algorithm is developed for evaluating the damage state of buildings subjected to earthquakes. Nonlinear response history analysis is used to generate the time histories of each building subjected to each earthquake. This report summarizes the analysis procedure used to extract data and describes the different classification algorithms that are developed to predict damage state....

The central United States has undergone a dramatic increase in seismicity over the past 6 years (Fig. 1), rising from an average of 24M ≥3 earthquakes per year in the years 1973–2008 to an average of 193M ≥3 earthquakes in 2009–2014, with 688 occurring in 2014 alone. Multiple damaging earthquakes have occurred during this increase including the 2011M 5.6 Prague, Oklahoma, earthquake; the 2011 M...

Post-earthquake road traversability is a critical factor that affects traffic conditions. Therefore, post-earthquake simulation method considering was proposed in this study. First, the impact ranges of earthquake-induced building collapse and fire spread buildings were analyzed, determined accordingly. Subsequently, flow predicted based on characteristics, micro-level vehicle behaviors simulat...

[1] We combine a viscoelastic model for the interseismic process and an elastodynamic model for the coseismic process to explore the dynamics (over multiple earthquake cycles) of two parallel strike-slip faults embedded in a two-dimensional full space. The step over fault geometry results in a buildup of heterogeneous fault stress near the step over. This heterogeneous stress accumulates at the...

Spurred in part by the rising economic costs of natural disasters, there has been a dramatic increase in efforts aimed at estimating the direct and indirect losses caused by earthquakes. For example, in 1997 the journal Earthquake Spectra devoted a special issue to loss estimation. Papers appearing in that publication ranged from cost-benefit analyses of structural rehabilitation strategies (D’...

This paper deals with the analysis of the reliability of information concerning damages caused to buildings by earthquakes. This research was started after analyzing a huge amount of written sources drawn up after 1930 Irpinia (southern Italy) earthquake. The analysis led to delineate damage ‘scenarios’, useful in trying to mitigate seismic risk for most affected towns. Once analyzed the effect...

Crustal fluids exist near fault zones, but their relation to the processes that generate earthquakes, including slow-slip events, is unclear. Fault-zone fluids are characterized by low electrical resistivity. Here we investigate the time-dependent crustal resistivity in the rupture area of the 1999 Mw 7.6 Izmit earthquake using electromagnetic data acquired at four sites before and after the ea...

The 12 May 2008 Wenchuan earthquake (Mw 7.9) ruptured the active Longmen Shan thrust belt bounding the eastern margin of the Tibetan plateau against the Sichuan basin (Fig. 1) (Burchfiel et al., 2008). Initial observations of this devastating earthquake were reported in several short papers focusing on coseismic slip and earthquake-fault geometry (e.g., Wang et al., 2008; Xu et al., 2009; Lin e...
