In May 1997, a large earthquake shook the Kermadec Islands region in the South Pacific Ocean. A little over 20 years later, in September 2018, a second big earthquake hit the same location, its waves ...

The mechanism facilitating the smooth movement of the oceanic lithosphere over the underlying asthenosphere (upper mantle) remains poorly understood. Recently, researchers from Japan investigated the ...

New research from The University of Texas at Austin could change the way scientists think about potential damage from earthquakes. The study examined data from one of the densest seismic arrays ever ...

Scientists have known that seismic waves slow down when passing through ultra-low velocity zones, or ULVZs, but only knew they existed around hotspots that create volcanic island chains. Now, a new ...

On a sunny morning in September 1985, a massive earthquake killed more than 9,000 people in Mexico City, even though the epicenter of the earthquake was some 200 miles away. The worst damage happened ...

Large quakes produce shaking at a variety of frequencies. Some waves can travel hundreds of miles, and are amplified by local geological conditions. By Thomas Fuller Thomas Fuller has reported on why ...

Mars has had its first CT scan, thanks to analyses of seismic waves picked up by NASA’s InSight lander. Diagnosis: The Red Planet’s core is at least partially liquid, as some previous studies had ...
