Can a drone reveal the murky secrets of San Francisco Bay?

Measurements of suspended sediment concentrations reveal a lot about the health of a waterway, but information has been difficult to obtain. A new approach uses a drone to take high-resolution photos to reveal turbidity.

Where can flooded fields help replenish groundwater?

Overpumping in California’s Central Valley has depleted groundwater storage capacity and caused the land to sink. A new model could help zero in on where water managers can replenish aquifers by flooding fields.

What can machine learning tell us about the solid Earth?

Scientists are training machine learning algorithms to help shed light on earthquake hazards, volcanic eruptions, groundwater flow and longstanding mysteries about what goes on beneath the Earth’s surface.

Rescuing geologic and climate records

Postdoc Daniel Ibarra recently traveled to the Philippines to collect cave deposits that are considered key to understanding changes in climate during ancient times.

Volcanoes, archaeology and the secrets of Roman concrete

Geophysical processes have shaped Pozzuoli, Italy, like few other places in the world. Stanford students applied modern tools to understand those links and what it means to live with natural hazards as both threat and inspiration.

Catalina Island is sinking and tilting

A new analysis of marine fossils and seismic data offers keys to better modeling of global sea levels and earthquake risk in Southern California.

Researchers map susceptibility to human-made earthquakes

Stanford researchers have mapped local susceptibility to human-made earthquakes in Oklahoma and Kansas. The new model incorporates physical properties of the Earth’s subsurface and forecasts a decline in potentially damaging shaking through 2020.

What makes volcanoes dangerous?

Recent eruptions offer reminders that lava, ash and size don’t fully explain how volcanoes become deadly.
