What to know about Plate tectonics shaped the Cradle of Civilization by merging two ancient rivers, study suggests

A new study published in Nature Geoscience suggests that the Euphrates River was formed by the merging of two ancient rivers, the Paleo-Karasu and Paleo-Murat, due to tectonic activity. The research utilizes seismic and topographic data to trace how these rivers shifted from the Mediterranean toward the Arabian Plate, contributing to the formation of the Fertile Crescent.

Why it matters

Flowing over 1,700 miles from Turkey through Syria and Iraq, the river played a crucial role in sustaining the region known as the "Cradle of Civilization." Yet, researchers aren't sure about the river's origins or how tectonic activity might have shaped its…

Common ground

A new study, published in Nature Geoscience, suggests that two ancient rivers, diverted by shifting plate tectonics, merged to form this vital river.
