Escalating activity along a fault line in the Sea of Marmara is moving closer to Istanbul, seismologists warn.

The ground beneath the Sea of Marmara is not just restless, it is organizing itself in a pattern that points directly toward Istanbul. A decade of seismic data now suggests that ruptures along the ...

In April 2025, the Main Marmara Fault below the Sea of Marmara in northwestern Türkiye experienced its largest earthquake in ...

When we think of earthquakes, we imagine sudden, violent shaking. But deep beneath the Earth's surface, some faults move in near silence. These slow, shuffling slips and their accompanying hum -- ...

A new twist on the San Andreas fault could shake up southern Californians preparing for the Big One. The southern San Andreas isn’t vertical in most places, as previously thought. Instead, it twists ...

The magnitude 7.8 earthquake that rocked parts of Turkey and Syria on Monday, killing more than 23,000 people, resembles a threat that Californians could potentially face. The same type of fault runs ...

In central Turkey, beneath the arid plains surrounding Lake Tuz, a silent geological shift is underway. A fault zone once thought to mirror the lateral motion of neighboring systems is instead tearing ...

A small part of the San Andreas Fault that was thought to quietly slide without shaking its neighbors may actually be capable of strong earthquakes, including magnitude-6 shakers, a new study finds.

When a seismologist visited the site of the 2019 Ridgecrest earthquakes two days after the event, he noticed something strange. Pebble- to boulder-sized rocks clearly had been moved by the earthquakes ...

Some of the largest and deadliest earthquakes in recent years hit where earthquake hazard estimates didn't predict massive quakes. A detailed computer model of large earthquakes in Japan and Taiwan ...
