Earthquake clustering phenomena such as aftershocks, foreshocks, and pairing of mainshocks are prominent and characteristic features of earthquake occurrence. Because the earthquake nucleation process controls the time and place of occurrence of earthquakes, non-linear dependence of nucleation times on stress changes can strongly affect the spatial and temporal patterns of earthquake occurrence...

Trauma experience not only could predict longterm physical and mental health problems, but also could have impact on the cognitive processes. Modified Stroop task and subliminal masked priming task were used to examine the automatic cognitive processing of earthquake-related stimulus (disaster-related, rescue-related, and earthquake-unrelated words) of healthy undergraduates at one month and tw...

The 5 September 2012 M(w) 7.6 earthquake on the Costa Rica subduction plate boundary followed a 62-y interseismic period. High-precision GPS recorded numerous slow slip events (SSEs) in the decade leading up to the earthquake, both up-dip and down-dip of seismic rupture. Deeper SSEs were larger than shallower ones and, if characteristic of the interseismic period, release most locking down-dip ...

The main components which affect the earthquake damage grades classification of multistory masonry buildings and the damage characters are summarized and analyzed through the statistics and analysis of a large number of previous earthquake damage data. According to the standard of earthquake damage grades classification, the damage numbers of each component of multistory masonry buildings under...

A variety of user-friendly spreadsheet templates have been developed for geoscience studies. However, the use of the built-in matrix functions within spreadsheet programs, such as Excel, is not particularly straightforward, lowering the value of spreadsheet programs for matrix-based computations, such as multiple regression analyses. Therefore, this study first developed two applications for Ex...

Because of the availability of high-resolution satellite imagery, remote sensing data has become an attractive source of data for identifying post-earthquake damage. Recently, several semiautomated methods for earthquake damage detection have been developed. These methodologies fall into two general categories: change detection and thematic classification. In change detection, both preand post-...

In order to better research the role helicopter played in the earthquake rescue, a helicopter earthquake rescue mission modeling method based on multi-agent was proposed. The elements of the earthquake environment modeling were described. Typical helicopter rescue missions in earthquake relief were divided into three basic types, and the mission flow was carded. The division and function of age...

The development of seismic vulnerability evaluation standards for reinforced concrete buildings in Japan is briefly reviewed. Damage statistics are shown to indicate that severe damage was observed in a relatively small percentage of existing buildings even after damaging earthquakes in the world. Therefore, a simple screening procedure is necessary to identify such vulnerable buildings out of ...

1. The multidimensional character of seismicity: time, space, and earthquake focal mechanism need to be modeled. The latter is a symmetric second-rank tensor of a special kind. 2. The intrinsic randomness of earthquake occurrence, necessitating the use of stochastic point processes and appropriate complex statistical techniques. 3. The scale-invariant or fractal properties of earthquake process...
