Research reveals structural changes in the inner core's surface, indicated by differences in seismic wave pairs.

Seismic waves suggest the planet's solid inner core is being pulled out of shape – and it has undergone these changes over ...

On Feb. 7, 1812, there was perhaps the most notable of three large earthquakes that shook the New Madrid seismic zone that ...

Santorini, and other Greek islands in the region, are in the middle of an "unprecedented" seismic swarm or crisis - the name ...

The tremors continue to rise in and around Santorini, Amorgos, Anafi and Ios, sparking fears of a larger disaster.

Unprecedented Seismic Activity Seismic activity is often the first indicator of changes deep within the Earth. Recently, ...

Dr. John Ebel, a geophysics professor at Boston College, explained the movement of tectonic plates, including the North American Plate, which Maine is centered on, is responsible for the seismic event ...

And we see that seismic waves slow down there." Earth scientists therefore call these regions "Large Low Seismic Velocity Provinces" or LLSVPs. "The waves slow down because the LLSVPs are hot ...
