In this study, for supporting global rescue operations, we will propose a new earthquake damage detection method, based on a combination of earthquake damage estimation using earthquake information (magnitude, location of source, detailed ground condition, and attenuation equation for distance) and change detection by means of remote sensing data. First, to find collapsed buildings and houses o...

The Karmania Hazard Model (KHM) is a GIS-based application for earthquake scenario development and disaster management. The lack of integrated and automated tools for estimating resources needed in the aftermath of an earthquake during the disaster response phase motivated the design and implementation of a comprehensive, interactive, and user-friendly model. This model draws on datasets integr...

Earthquakes are one of the most destructive natural hazards on our planet Earth. Hugh earthquakes striking offshore may cause devastating tsunamis, as evidenced by the 11 March 2011 Japan (moment magnitude Mw 9.0) and the 26 December 2004 Sumatra (Mw 9.1) earthquakes. Earthquake prediction (in terms of the precise time, place, and magnitude of a coming earthquake) is arguably unfeasible in the ...

Introduction The heterogeneities in the crust and upper mantle structure as well as the complex source rupture process have an important influence on regional seismic wavefield, particularly for high-frequency waves. Moreover small-scale heterogeneities such as for the sedimentary basin introduce significant amplification of ground motion, which lead to long ground shaking over several minutes ...

In a spatial point set, clustering patterns (features) are difficult to locate due to the presence of noise. Previous methods, either using grid-based method or distance-based method to separate feature from noise, suffer from the parameter choice problem, which may produce different point patterns in terms of shape and area. This paper presents the Collective Nearest Neighbor method (CLNN) to ...

The rupture process and tectonic surroundings of the 2008 Wenchuan, China, earthquake are both complex in a way that might be related to the heterogeneous stress field of the Longmen Shan region. In this study, we construct dynamic models with heterogeneous initial stress to reproduce a kinematic inversion result by Wen et al. (2012) and investigate the physical mechanisms of the variable slip ...
