Determining Earthquake Locations in NW Himalayan Region: An Application of Particle Swarm Optimization

چکیده
Inversion problems in seismology deal with the estimation of the location of an earthquake from the observations of the arrival times of the body waves. This problem is modeled as a non-linear optimization problem in which the objective function to be minimized is the discrepancy between the observed and the calculated travel times. This paper attempts to determine the seismic location in the upper mantle of the Earth’s crust using a new nature inspired optimization technique named “particle swarm optimization”. With the help of this technique, the location of the earthquakes in the northern Himalayan and Hindu Kush region is determined. The location of the Earthquakes up to the depth 100 Km are considered. An advance version of PSO namely LXPSO is used for the inversion of data.

Our country has experienced flood and earthquakes in most cities, due to its location in the Alpine-Himalayan mountain belt, with varying climates which they are so destructive. The earthquake is considered as a harmful natural hazard that affect human society around the world, and is extremely dangerous because it cannot be foreseen and its energy can be freed at any time, and is classified in...
متن کاملPREDICTION OF EARTHQUAKE INDUCED DISPLACEMENTS OF SLOPES USING HYBRID SUPPORT VECTOR REGRESSION WITH PARTICLE SWARM OPTIMIZATION
Displacements induced by earthquake can be very large and result in severe damage to earth and earth supported structures including embankment dams, road embankments, excavations and retaining walls. It is important, therefore, to be able to predict such displacements. In this paper, a new approach to prediction of earthquake induced displacements of slopes (EIDS) using hybrid support vector re...
