Thanks to 20 years of seismic data processed through one of the world’s most powerful supercomputers, scientists have created the first complete, 3D visualization of a mountain-size rock called the Kumano Pluton buried miles beneath the coast of southern Japan. They can now see the rock could be acting like a lightning rod for the… Continue Reading Big Data Imaging Shows Rock’s Big Role in Channeling Earthquakes in Japan

Are Deep Fluids Behind the Largest Earthquakes? ‘Not So Fast!’ Says UT Graduate Student
Sandwiched between tectonic plates are layers of material that show up as thin shadows on seismic tomography, a kind of CT scan of the Earth. For years, scientists assumed the anomalies were signs of highly pressurized water squeezed into densely packed rock and that the fluid acted as a kind of hair-trigger on earthquake faults.… Continue Reading Are Deep Fluids Behind the Largest Earthquakes? ‘Not So Fast!’ Says UT Graduate Student
Slow Slip’ Earthquakes’ Hidden Mechanics Revealed
Slow slip earthquakes, a type of slow motion tremor, have been detected at many of the world’s earthquake hotspots, including those found around the Pacific Ring of Fire, but it is unclear how they are connected to the damaging quakes that occur there. Scientists at The University of Texas at Austin have now revealed the… Continue Reading Slow Slip’ Earthquakes’ Hidden Mechanics Revealed
Sinking Sea Mountains Make and Muffle Earthquakes
Subduction zones — places where one tectonic plate dives beneath another — are where the world’s largest and most damaging earthquakes occur. A new study has found that when underwater mountains — also known as seamounts — are pulled into subduction zones, not only do they set the stage for these powerful quakes, but also… Continue Reading Sinking Sea Mountains Make and Muffle Earthquakes
UTIG Seminar Notes: Kelly Olsen explains why some regions are more prone to powerful earthquakes than others
The final UTIG seminar of the Fall semester is reserved for graduate students to practice their presentations for AGU Fall. This year’s practice talks will be given by UTIG grad students Xian Wu, Kelly Olsen and Janaki Vamaraju. We asked each student to give us a sneak-preview into what they’ll be talking about and why… Continue Reading UTIG Seminar Notes: Kelly Olsen explains why some regions are more prone to powerful earthquakes than others
