Some thesis about a source location of Marina Region(N part) are confirming  based on Electoquakes...Also,I catched a discovery during my analysis!!!So,implications are showing to YellowSea Region...
Conclusion working as a whole are presenting;

By the way,I wondered to Seismicity History of Marina Trench Geography;

So,a structure as compatible to yellow circle as ~ which  is corelating with seismicty specifications!!!

As second part,I especially focalised to Yellowsea Region...conclusions of my some researches about Yellowsea Region;

By the way,Special thanks to Google Earth...Thus,I can express a geophysical source determination  for circle centre with my yellow circle 

Also,some internet sources are subject about Yellowsea Region...A information among most interest;

Detailed Analysis;

TAI HO Consolidated Impact Crater Region is among identified regions.Other locations are into Sea Regions which are expressing to very powerful implications
