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 deployed and found that earthquakes emit their strongest seismic shockwaves in four opposing directions. The effect, which leaves a pattern resembling a four-leaf… Continue Reading Seismic Shockwave Pattern May Be Redirecting Earthquake Damage
Frictional Properties of Natural Fault Rocks Explain Slip
In a new Nature Geosciences paper, Im, Saffer, Marone, and Avouac report on computer models that incorporate laboratory measurements from natural fault rocks to study fault slip and rupture behavior. They show that the frictional properties of these natural fault rocks can explain the spectrum of slip behavior observed on tectonic faults that spans from… Continue Reading Frictional Properties of Natural Fault Rocks Explain Slip
