An aftershock results from the sudden change in stress occurring within and between rocks and the previous release of stress brought on by the principal earthquake. .

.

each correlation trace is weighted according to the mean amplitude of the noise in a 200.

The earthquake focal depth is also determined in the process by using the time separations of the direct P and depth phases.

In this work we propose a new method by using converted waves for investigating accurately the locations of lower crustal earthquakes in the North China.

Sep 12, 2009 · It uses theoretical Green's function and a time-domain deconvolution with positivity constraint to estimate the source time function from the teleseismic P waveforms.

The precise focal depth of earthquakes is a crucial parameter for better characterising of complex tectonic zones, especially where seismogenic faults occur at different depths.
