International joint research for geoelectromagnetic investigation of divergent plate boundary at Afar in Ethiopia

Project Gist

On-land geo-electromagnetic research on a subaerial sea-floor spreading center at Afar Depression in Ethiopia

Keywords

Afar Depression、divergent plate boundary、sea-floor spreading、geo-electromagnetic survey、geomagnetic anomaly

Background, Purpose, and Project Achievements

At Afar Depression in Ethiopia, we can investigate the feature of a sea-floor spreading center on land. We have planed a collaborative research project among Japanese and Ethiopian researchers for geo-electromagnetic surveys at the subaerial sea-floor spreading center, including aero-geomagnetic surveys with unmanned airplanes in near future.

Future Prospects

Aero-geomagnetic surveys with unmanned airplanes at Afar Depression for detailed mapping of geomagnetic anomalies at the sea-floor spreading center. Geo-scientific field excursions in Japan and Ethiopia as an international educational program for young geoscientists.
