2014 Aegean Sea Earthquake: Introduction

Most ruptures travel along a fault at speeds slower than the shear waves they generate, so the shaking arrives a beat ahead of the source. But on 24 May 2014, in the northern Aegean Sea between Greece and Turkey, a fault rupture did something stranger: the eastern segment ran faster than the S-waves themselves, becoming what seismologists call a supershear earthquake - a kind of seismic sonic boom in which the rupture front overtakes the waves it is making. The magnitude was 6.9, which is large but far from catastrophic by Aegean standards. The damage was real but bounded. What made the 2014 event remarkable was less what it did and more what it taught us about how the ground breaks.

To the east, the North Anatolian Fault runs through the Sea of Marmara as a long strike-slip wound, the Anatolian plate sliding westward against the Eurasian plate. To the south and west, the H...

A shorter section ruptured first, west of the hypocenter. Then the rupture jumped east and tore along a longer, 65-kilometer segment - and on this longer s...

On the Turkish island of Imbros - now officially Gökçeada, off Turkey's northern Aegean coast - old houses cracked and walls fell. Thirty people were taken to hospitals with minor injuries. In Çanakkale on the mainland Tur...

Three people died in the broader earthquake area, according to Çanakkale officials - real human beings whose families that morning had not expected to be making funeral arrangements. E...
