Catastrophic outburst floods carved Greenland’s ‘Grand Canyon’
Buried a mile beneath Greenland's thick ice sheet is a network of canyons so deep and long that the largest of these has been called Greenland's "Grand Canyon."
Geology
Scientists find evidence of how platinum metals form under 60 million-year-old Scottish volcano
Research carried out by scientists at Keele University, the University of Manchester and University College Dublin has shed new light on how precious metals are concentrated in igneous rocks.
Geology
New study finds connection between fault roughness and the magnitude of earthquakes
A new study led by McGill University has found that tectonic plates beneath the Earth's surface can show varying degrees of roughness and could help explain why certain earthquakes are stronger than others.
Geology
The sleeping giant – supervolcano of the Andes
Under the volcanoes in the Andes where Chile, Argentina and Bolivia meet, there is a gigantic reservoir of molten magma.
Geology
Seismic map of North America reveals geologic clues, earthquake hazards
How do mountains form? What forces are needed to carve out a basin? Why does the Earth tremble and quake?
Geology
Tectonic plates started shifting earlier than previously thought
An enduring question in geology is when Earth's tectonic plates began pushing and pulling in a process that helped the planet evolve and shaped its continents into the ones that exist today.

Study suggests rainfall triggered 2018 Kīlauea eruption
In May 2018 Kīlauea volcano on the island of Hawaii erupted, touching off months of intense activity. Through August, incandescent lava from fissures spewed hundreds of feet in the air, and billowing ash clouds reached as high as six miles into the atmosphere.
Geology
A possible relationship between the red color of stalagmites and paleoclimatic changes is found
The CENIEH has participated in a study where spectroscopic techniques were used to investigate the cause of the red coloration of the stalagmites in Goikoetxe Cave and its possible use as an indicator of paleoclimatic changes in northern Spain.
Geology
New geochemical tool reveals origin of Earth’s nitrogen
Researchers at Woods Hole Oceanographic Institution (WHOI), the University of California Los Angeles (UCLA) and their colleagues used a new geochemical tool to shed light on the origin of nitrogen and other volatile elements on Earth, which may also prove useful as a way to monitor the activity of volcanoes.

Journey to the center of the Earth – First of its kind experiment uses diamond anvils to simulate the Earth’s core
In an effort to investigate conditions found at the Earth’s molten outer core, researchers successfully determined the density of liquid iron and sound propagation speed through it at extremely high pressures.
Geology
Timing of large earthquakes follows a ‘devil’s staircase’ pattern
At the regional level and worldwide, the occurrence of large shallow earthquakes appears to follow a mathematical pattern called the Devil's Staircase, where clusters of earthquake events are separated by long but irregular intervals of seismic quiet.

Heavy iron isotopes leaking from Earth’s core
Earth's molten core may be leaking iron, according to researchers who analyzed how iron behaves inside our planet.
The boundary between the liquid iron core...
