(Phys.org)—A pair of researchers with the Berkeley Seismological Laboratory in California has found possible evidence of an ultralow-velocity zone (ULVZ) feeding the Icelandic plume. In their paper published in the journal ...
A team of researchers from the University of Cambridge have developed a new way of measuring the pressure inside volcanoes, and found that it can be a reliable indicator of future eruptions.

(Phys.org) —A team of researchers in France has successfully demonstrated small-scale reflection of seismic waves around a desired geological area. In their paper published in the journal Physical Review Letters, the researchers ...
(Phys.org) —The Earth's outer layer is made up of a series of moving, interacting plates whose motion at the surface generates earthquakes, creates volcanoes and builds mountains. Geoscientists have long sought to understand ...
