In order to expand our knowledge about magnetic structures under a sea-floor spreading center and the formation process of magnetic stripes, we are proceeding an on-land geo-electromagentic research plan at the divergent plate boundary in Afar Depression, Ethiopia, where we can directly investigate into a sea-floor spreading center on land. We will introduce our plan and report the progress of geomagnetic and geological surveys we have performed.
