Italy’s Apennine Mountains mystery: Why is Earth’s crust slowly ‘unzipping’ deep underground, and what is happening beneath the surface?
3+ day, 2+ hour ago (470+ words) Scientists studying Italy’s Apennine Mountains have found a strange process deep below the surface. The Earth’s crust in this region appears to be slowly pulling apart, almost like a zip opening from underground. The finding comes from researchers at the…...
Gondwana Was Earth's Largest Supercontinent, and It Sparked the Cambrian Explosion
3+ day, 21+ hour ago (228+ words) The 75% threshold itself, meanwhile, was always somewhat arbitrary. Joseph Meert, a paleogeographer at the University of Florida who established that threshold in 2012, has acknowledged as much. "A lot of people have taken it to be a significant exact number, and…...
Seafloor Geology
5+ day, 23+ hour ago (97+ words) Part way through Dive 07 of the 2026 American Samoa ROV + Mapping Exploration expedition, seafloor geology shifted from terraces and sheets to possible pillows and ferromanganese-encrusted flows and cobbles intermixed. The shift in structure did not seem to significantly impact the biological…...
Seismic anisotropy reveals stress rotation caused by magmatic-tectonic interactions in the Natron rift

Structural Geology and Tectonics Exemplary phase identification (station GE01; same as in Figure 3). (top to bottom) Horizontal component waveform, spectrogram,…...
A massive plume deep beneath Africa is pulling the continent apart
1+ week, 6+ day ago (1058+ words) Computer models are helping scientists explain a puzzling pattern of deformation beneath the East African Rift System. The results point to the African Superplume, a vast upwelling of hot mantle material deep inside Earth, as the source of unusual motion…...

Volcanoes deliver rock older than the continents
3+ week, 6+ day ago (782+ words) No drill has ever reached the mantle, so scientists depend on volcanoes to deliver the samples instead. Lava from Hawaii and Iceland carries helium, ruthenium, and tungsten signatures that point to a source near the boundary with Earth's core, about…...
