Tectonic Dynamics in the Alpine-Pannonian Region

The Alpine-Pannonian region represents a complex junction where the convergent evolution of the Eurasian and Adriatic plates has given rise to the Alps, Carpathians and the intervening Pannonian Basin. Initial continental collision during the Cenozoic generated orogenic wedges and high-pressure metamorphism, followed by slab rollback beneath the Eastern Alps and Carpathians. This rollback induced back-arc extension in the Pannonian realm, leading to widespread thinning of the crust, basin subsidence and development of extensional fault systems. Successive slab-tearing events beneath the Eastern Alps created slab gaps that channelled asthenospheric upwelling, promoting mantle-driven uplift and facilitating crust–mantle decoupling. The Periadriatic fault system and associated strike-slip networks accommodated lateral extrusion of Alpine crust toward the Pannonian Basin. Today, low to moderate seismicity, rapid sedimentation in extensional depocentres and active fault offsets attest to ongoing tectonic processes. Understanding these dynamics is critical for seismic hazard assessment, hydrocarbon and geothermal exploration, and offers a natural laboratory for studying the interplay of collision, rollback and back-arc extension on a continental scale.

Tectonic Dynamics in the Alpine-Pannonian Region publication trend

The graph below shows the total number of articles in tectonic dynamics in the alpine-pannonian region across all publications each year (not limited to Nature Index journals).

Technical terms

Subduction polarity: Direction in which one tectonic plate descends beneath another.

Slab rollback: Retreat of the hinge of a subducting plate, driving extension in the overriding plate.

Back-arc extension: Crustal stretching behind a volcanic arc induced by slab rollback.

Strike-slip fault: Vertical fracture along which lateral displacement occurs.

Pannonian Basin: Neogene back-arc extensional basin between the Alps and Carpathians, formed by slab rollback processes.
