Earthquake rupture along Main Marmara Fault shows eastward progression towards Istanbul

In April 2025, the Main Marmara Fault, beneath the Marmara Sea in northwest Turkey, experienced its largest earthquake in more than 60 years. In a study published in Science, a team of researchers led by Professor Patricia Martínez-Garzón of the GFZ Helmholtz Geoscience Center in Potsdam, Germany, analyzes nearly two decades of seismic data surrounding the April 2025 magnitude M 6.2 earthquake.
