The Alps Revisited—4D-MB, the German Contribution to the Alp Array Mission

4D-MB is a multi- and interdisciplinary project that stands as an integral part of the international Alp Array mission. It helps test the advanced hypothesis that re-organizations of the Earth’s mantle during the collision of tectonic plates have immediate as well as long-lasting effects on the earthquake distribution, crustal motion and landscape evolution in the mountain belts. The Alp-Array consortium involves 64 institutions distributed in 17 countries.
