On a dynamic planet like Earth, it can be easy for drivers of change to go unnoticed – but scientists have now established and investigated an unexpected link between the Sun and our homeworld. Sunspots, and therefore solar activity, cause seismic ...

Yes, Hurricane Melissa affected seismic activity, but it did not cause a crack in the seafloor that will lead to a major earthquake. Our expert debunks a viral claim.

A recent study published in Earth and Planetary Science Letters is the first to directly link earthquakes to climate change-induced glacial melt. Scientists analyzed 15 years of seismic activity in the Grandes Jorasses—a peak that is part of the Mont Blanc massif between Italy and France—to better understand this association.

After the 1975 earthquake, there was a greater emphasis on monitoring the motion of the south flank. Hawaiian Volcano Observatory and the University of Hawaiʻi at Mānoa installed continuous GPS instruments on Kīlauea’s south flank that recorded the steady seaward motion of the south flank at a rate of about 5 centimeters (2 inches) per year.

The quake came during a cluster that saw over a dozen other earthquakes reported over a 24-hour period, the USGS map shows.
