Wildfires leave lasting risks: Improving predictions of hazardous debris flows in burned areas

Researchers developed a new method to predict debris flows in post-fire landscapes, incorporating vegetation recovery, which reduces unnecessary warnings and improves accuracy. The updated method reflects changes in soil absorption and plant water uptake after wildfires, providing more accurate hazard maps and rainfall threshold guidance.

How landslides happen without heavy rainfall: Early strong runoff coincides with weak geomaterials

A study published in Geology found that up to 75.7% of landslides occur during low or no rainfall periods, with early-stage rainfall reaching the sliding surface through three runoff supply modes and two migration stages. The team recommends mass monitoring, public education, and engineering mitigation measures to prevent such disasters.

New discovery of younger Ediacaran biota

Researchers have uncovered a new, exceptionally preserved fossil site in Newfoundland, Canada, dating back to 551 Ma. This find dramatically alters our understanding of the 'Kotlin Crisis,' the first extinction event in animal history, which is now estimated to have resulted in an astonishing 80% loss of biodiversity.

Cobalt mineralogy at the Iron Creek deposit, Idaho cobalt belt, USA: Implications for domestic critical mineral production

A new study published in Geology evaluates the potential for domestic cobalt extraction from the Idaho Cobalt Belt, which hosts the second largest known domestic resource of critical mineral cobalt. The researchers conclude that the ore from Idaho should be divided and processed for copper and cobalt separately to meet growing demand.

New articles for Geosphere posted early online

Two new studies examine the Late Triassic tectonic stress field of the southwestern Ordos Basin and its implications for regional geology. The research also explores a new Cambrian stratigraphic unit in the Grand Canyon, USA, and the progressive unroofing of the Big Maria and Riverside Mountains in southeastern California.

Geosciences at the Crossroads of America

The 57th annual meeting of the Geological Society of America's South-Central Section will take place in Oklahoma, USA, from March 13-14. The event features a diverse program covering various geologic disciplines and includes environmental-related sessions on topics such as hydrogeology and unconventional resources.

New GSA Bulletin articles published online ahead of print

Researchers studied the nature and dynamics of China and Tibet, identified a possible sea-level fall trigger for youngest rejuvenated volcanism in Hawaiʻi, and explored porphyry copper mineralization. New data from El Kef Coring Project in Tunisia reveals unexpected differences in stratigraphic successions, challenging previous assumpt...
