I discussed near "two seismic event" as time considering Outer Core Structure; >4/16_M4.3,Fannuj Region >4/17_M4.6,Central Mid-Atlantic Ridge I observe Algeria-Niger border ~ for central region as volumetric.Next,I noted some developments correlated to circle; >4/18_M4.4,Bardaskan Region >4/21_M5.3,Bardarbunga Region >4/21_M4.6,South Atlantic Ocean >4/24_M4.8,Reykjanes Ridge >5/1_M4.6,Socotra Region >5/3_M4.2,Quchan Region >5/6_M4.5,Norwegian Sea >5/13_M4.8,Central Mid-Atlantic Ridge Data Source:USGS Yes,you are right,I cite a volumetric develepment thesis based on outer core structure for these events. Thus,I hope that as nice an approach for Earth Researchers...
