The bright white region of this image shows the icy cap that covers Mars’ south pole, composed of frozen water and frozen carbon dioxide. ESA’s Mars Express imaged this area of Mars on December 17, 2012, in infrared, green, and blue light, using its High Resolution Stereo Camera. Credit: ESA/DLR/FU […]

This study, published in the journal Geologyin collaboration with the University of Western Australia and the China […]

A fortuitous orbit of the International Space Station allowed the astronauts this striking view of Sarychev Volcano (Russia’s Kuril Islands, northeast of Japan) in an early stage of eruption on June 12, 2009.

Photo of eruption at Mount Redoubt in Alaska in 2009. Credit: Game McGimsey, USGS New research methods may lead to earlier predictions of volcanic eruptions. Although there are telltale signs that a volcano is likely to erupt in the near future – an uptick in seismic activity, changes in gas […]

DDE aims to harmonize deep-time Earth data based on a knowledge system to investigate the evolution of Earth, including life, Earth materials, geography, and climate. Integrated methods include artificial intelligence (AI), high performance computing (HPC), cloud computing, semantic web, natural language processing, and other methods.

A computer-created graphic of a river meandering and associated sediment deposits. The lighter blue represents the river’s current flow. The darker blue represents old areas of flow that have been cut off due to the river’s meandering. The striped regions along the flow paths represent sediment deposits in the form […]

Shiveluch volcano has had more than 40 violent eruptions over the last 10,000 years. The last gigantic blast occurred in 1964, creating a new crater and covering an area of nearly 100 square kilometers with pyroclastic flows. But Shiveluch is actually currently erupting, as it has been for over 20 […]
