Scientists model landscape formation on Titan

A new hypothesis reveals that a global sedimentary cycle driven by seasons could explain the formation of landscapes on Saturn’s moon Titan. The research shows the alien world may be more Earth-like than previously thought.

Stanford’s Richard Nevle discusses his new book

Richard Nevle, deputy director of Stanford’s Earth Systems Program, discusses his forthcoming collection of essays about the Sierra Nevada mountain range, The Paradise Notebooks.

New model may improve Bay Area seismic hazard maps

Using the Santa Cruz Mountains as a natural laboratory, researchers have built a 3D tectonic model that clarifies the link between earthquakes and mountain building along the San Andreas fault for the first time. The findings may be used to improve seismic hazard maps of the Bay Area.

Extinction changes rules of body size evolution

A sweeping analysis of marine fossils from most of the past half-billion years shows the usual rules of body size evolution change during mass extinctions and their recoveries. The discovery is an early step toward predicting how evolution will play out on the other side of the current extinction crisis.

Giant friction experiment at Kīlauea volcano

A new analysis of the 2018 collapse of Kīlauea volcano’s caldera helps to confirm the reigning scientific paradigm for how friction works on earthquake faults. The model quantifies the conditions necessary to initiate the kind of caldera collapse that sustains big, damaging eruptions of basaltic volcanoes like Kīlauea and could help to inform forecasting and mitigation.

Discovery illuminates a 120-million-year record of ancient Earth

Stanford-led expeditions to a remote area of Yukon, Canada, have uncovered a 120-million-year-long geological record of a time when land plants and complex animals first evolved and ocean oxygen levels began to approach those in the modern world.
