Where will the next big earthquake hit Istanbul?

The city of Istanbul is focus of great concern for earthquake researchers. This 15-million metropole is situated very close to the so-called North Anatolian...

Earthquakes can make thrust faults open violently and snap shut

It is a common trope in disaster movies: an earthquake strikes, causing the ground to rip open and swallow people and cars whole. The...

Lessons from Parkfield help predict continued fault movements after earthquakes

A new study shows that the San Andreas Fault continued to slip gradually for six to twelve years after the 2004 magnitude 6.0 Parkfield,...

Past Quakes at Fault: Abrupt Sinking of Seal Beach Wetlands

A California State University, Fullerton faculty-student study shows evidence of abrupt sinking of the wetlands near Seal Beach, Calif., caused by ancient earthquakes that...

Fault system off San Diego, Orange, Los Angeles counties could produce...

A fault system that runs from San Diego to Los Angeles is capable of producing up to magnitude 7.3 earthquakes if the offshore segments...

Ventura fault could cause stronger shaking, new research finds

A new study by a team of researchers, including one from the University of California, Riverside, found that the fault under Ventura, Calif., would...

Megathrust earthquakes

The raggedness of the ocean floors could be the key to triggering some of the Earth's most powerful earthquakes, scientists from Cardiff University have...

Earthquake faults are smarter than we usually think

Northwestern University researchers now have an answer to a vexing age-old question: Why do earthquakes sometimes come in clusters? The research team has developed a...

Alpine Fault theory takes shape

The Alpine Fault has been assumed to be a near vertical crack, however, research published last year by Victoria scientists suggests that the fault...

Biggest exposed fault on Earth discovered

Geologists have for the first time seen and documented the Banda Detachment fault in eastern Indonesia and worked out how it formed. Lead researcher Dr...

Subduction zone geometry: Mega-earthquake risk indicator

Mega-earthquakes (with a magnitude greater than 8.5) mainly occur on subduction faults where one tectonic plate passes under another. But the probability of such...

Fault curvature may control where big earthquakes occur

Major earthquakes -- magnitude 8.5 and stronger -- occur where faults are mostly flat, say University of Oregon and French geologists. Curvier faults, they...

To recover from next big quake, start today

Seismologists with the U.S. Geological Survey recently discovered that the Hayward Fault, considered the most dangerous fault in the San Francisco Bay Area, is...

Entire Himalayan arc can produce large earthquakes

The main fault at the foot of the Himalayan mountains can likely generate destructive, major earthquakes along its entire 2,400-kilometer (1,500-mile) length, a new...

Two San Francisco-area earthquake faults found to be connected

The most dangerous earthquake fault in the San Francisco Bay Area is connected to another, which means both could rupture simultaneously and unleash major...

New fault discovered in earthquake-prone Southern California region

A swarm of nearly 200 small earthquakes that shook Southern California residents in the Salton Sea area last week raised concerns they might trigger...

How Nature’s ‘Dislocations’ Occur

Every material can bend and break. Through nearly a century's worth of research, scientists have had a pretty good understanding of how and why....

Study Reveals New Earthquake Hazard in Afghanistan-Pakistan Border Region

University of Miami (UM) Rosenstiel School of Marine and Atmospheric Science scientists have revealed alarming conclusions about the earthquake hazard in the Afghanistan-Pakistan border...

Slow slip events can trigger earthquakes

In subduction zones, where one tectonic plate slides beneath another, slow, imperceptible slip, known as 'slow earthquakes' or 'slow slip events', can trigger powerful...

Study Finds Earthquakes Can Trigger Near-Instantaneous Aftershocks on Different Faults

According to a new study by scientists at Scripps Institution of Oceanography at the University of California San Diego, a large earthquake on one...
