effective ground evaluations on non-insitu concept

 We can suggest two effective approach as pratic for evaluating ground effects of far seismic events;

I)As first approach,evaluation shake sensing reports on distance-magnitude relations a big magnitude as relative.

II)As second approach,analysis of multistations 

This approaches are among techniques summaried for ground inspect of non-insitu concept.Explanation via blogger as a example for first description;

Second Approach:Comparative a procedure of spectrogram analysis of stations included same radius by source for evaluating ground effects of far seismic events that summarying as pretty effective method.In this mean,link acquired of pre-informations about common structure of applications:

Where,eligibility with autoprocess tricks of stations included same radius among most important headlines emphasized considering evaluation expressed!!!You are right👍I cite to elimination for aim expressed of multiple spectrogram images shared via link.With this conclusion,we can establish informations for ground structure matters of station regions on either instant and longtime ranges considering some dbase apps on concept of stations eliminated based on radial after far region events.

I will wait replies of geoenvironments related...

You are right!Subject positive conclusions of important efforts based on this methodology for  prediction field as a conclusion of second approach...For example,some presentations on USArray project of US are shortly summarying  evaluations  about catched such a potential of US;
