A team of researchers with the University of Ottawa has used teleseismic data from on- and off-shore sensors to learn more about the low-viscosity layer (LVL) present in a northern part of the Cascadia subduction zone. In ...
A Brown University study provides new evidence that the icy shell of Jupiter's moon Europa may have plate tectonics similar to those on Earth. The presence of plate tectonic activity could have important implications for ...
