Outline of Final Research Achievements

Based on the interpretation of 3D satellite images and shaded relief maps, we prepared a map and catalog of active faults of Afghanistan located west of the Himalayan collision zone. We then proposed active tectonic divisions of the country by integrating data on active faults, geology, and geophysics. We estimated a left-lateral slip rate of the Chaman fault near Kabul as 4-5 mm/yr based on the ages of offset fluvial terraces by cosmogenic nuclide dating. We propose that the faults surrounding the Kabul basin are capable of producing earthquakes higher than M7.

Academic Significance and Societal Importance of the Research Achievements

本研究は,アフガニスタンの活断層や地震テクトニクスに関する国際的にみても初めての実証的な研究である.本研究で地形の実体視に基づく活断層図を初めて作成し,今後の地球科学研究の基礎資料を提供できた.またチャマン断層の変位速度が北端へ向かって小さくなることが判明した.またカブール周辺の活断層が大地震を発生させる可能性のある活断層であることが明らかとなり,今後の地震災害軽減の基礎資料を提供した.また本研究を通して,アフガニスタンの若手研究者に我が国の活断層研究の技術移転を行うことができた.
