Earthquake depth impacts potential tsunami threat

Earthquakes of similar magnitude can cause tsunamis of greatly varying sizes. This commonly observed, but not well-understood phenomenon has hindered reliable warnings of local tsunamis.

Anatomy of an earthquake series

An international team led by scientists at GFZ Helmholtz Centre Potsdam, in collaboration with colleagues by Spanish, Italian and US institutions, is publishing a new scientific work on induced seismicity in Europe in ...

The giant geode of Pulpí

The geode of Pulpí is an 11-meter hollow ovoid with crystal-paneled walls. It is like those familiar couplets of stone interiors covered with bright crystallites, but so large that several people can fit inside. The crystals, ...

Earthquake in super slo-mo

A big earthquake occurred south of Istanbul in the summer of 2016, but it was so slow that nobody noticed. The earthquake, which took place at mid-crustal depth, lasted more than 50 days. A novel processing technique applied ...

Researchers report new understanding of deep earthquakes

Researchers have known for decades that deep earthquakes—those deeper than 60 kilometers, or about 37 miles below the Earth's surface—radiate seismic energy differently than those that originate closer to the surface. ...
