Seismological research is directly related to the incubation, occurrence, and evolution of earthquakes. Scientists seek to reveal potential earthquake precursors by monitoring the stress state of ...

Caltech researchers have developed a new method to measure soil moisture in the shallow subterranean region between the surface and underground aquifers. This region, called the vadose zone, is ...

When the edge of a Greenland glacier breaks off into the sea to become an iceberg, can a global seismic network "hear" it?

The blue path illustrates a core-penetrating seismic wave moving through a region in the outer core, where the seismic speed has increased because a low-density flow has moved into the region. Credit: ...
