Improving Microseismic PWave Source LocationWith Multiple Seismic Arrays
Using array analysis, the direction and distance to a seismic P wave source can be determined. However, individual arrays are limited in their geographical coverage and by their resolving capability, which is determined by the array aperture, configuration, and number of stations. We demonstrate these limitations on three large seismic arrays located in Japan, Europe, and California, and find t...
متن کاملOptimal wave focusing for imaging and microseismic event location
Focusing waves inside a medium has applications in geophysics in areas such as imaging and microseismic event location. The goal in focusing is to concentrate the wave energy at a specific time and location inside a medium. Various techniques have been devised and used to achieve this goal. Timereversal (TR) is a well-researched method that has been used routinely to focus waves. The ability of...
متن کاملSuperresolution Source Location with Planar Arrays
■ The challenge of precision source location with a radio-frequency antenna array has existed from the beginnings of radiometry and has continued in modern applications with planar antenna arrays. Early work in this field was limited to estimating single source directions in one dimension with systems like crossed-loop radiometers. Currently, more advanced systems attempt to estimate azimuth an...
متن کاملJoint microseismic event location with uncertain velocity
We study the problem of the joint location of seismic events using an array of receivers. We show that locating multiple seismic events simultaneously is advantageous compared to the more traditional approaches of locating each event independently. Joint location, by design, includes estimating an uncertainty distribution on the absolute position of the events. From this can be deduced the dist...
متن کاملTime-Arrival Location of Seismic P-Wave based on Wavelet Transform Modulus Maxima
The time-arrival location of seismic P-wave is an important problem in the seismic research field. The modulus maxima of wavelet transform is a useful method for picking up the singularities of function. For applying the modulus maxima method to investigate the arrival time, it is necessary to eliminate the influence of random factors. Based on standard deviation, we present a method to reduce ...
