Researchers map susceptibility to man-made earthquakes

Stanford researchers have mapped local susceptibility to man-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.

After the Big One: Understanding aftershock risk

Geophysicist Gregory Beroza discusses the culprits behind destructive aftershocks and why scientists are harnessing artificial intelligence to gain new insights into earthquake risks.

Hurricane Florence

Hurricane Florence: The science behind the storm

Atmospheric scientist Morgan O’Neill discusses what’s driving Florence, why it’s unusual, and how it could be connected to climate change and other storms brewing in the Atlantic.

Q&A: How does climate change affect human health?

Stanford experts discuss the linkages between climate change and health, an area that will be a focus of Stanford-led events at the Global Climate Action Summit in San Francisco.

Transparency may improve U.S. home buyout programs

New research finds government buyouts of homes in floodplains have often lacked transparency. This could deter residents from participating in managed retreat, one of the main strategies for adapting to areas becoming more flood-prone, Stanford researcher suggests.

Snake

Drought predictive of decrease in snakebites

Rattlesnake bites, contrary to public opinion, increase after periods of high rainfall, not drought, according to a Stanford-led study that examined 20 years of snakebite history in California.

Drinking water

Natural chromium sources threaten California groundwater

A study shows natural sources of hexavalent chromium are affecting more people and wells in California than industrial sources. But groundwater pumping may accelerate release of this carcinogen.

Arctic

Finding the pulse of the polar vortex

A new analysis of how air moves between two layers of Earth’s atmosphere reveals a deep system that could enable long-term weather forecasts and better climate models.

Mount Sinabung

Learning through sound

The audible world contains vast amounts of information about the world around us. Scholars from across Stanford are exploring this invisible landscape as a research tool and as a way of understanding each other.

Port Arthur

Bracing for sea level rise to boost national security

Storm season is upon us, the federal flood insurance plan is broken and sea level rise continues unabated. Stanford climate and policy experts Alice Hill and Katharine Mach look at issues related to rising seas with an eye toward increasing resilience and security.

Fuego Volcano

Beyond lava and ash: What makes volcanoes dangerous?

Recent eruptions offer reminders that lava, ash and size don’t fully explain how volcanoes become deadly. Geologists Gail Mahood and Donald Lowe describe some of the science and mysteries behind volcanic hazards. 

Cracked earth

Study casts doubt on the predictive value of earthquake foreshocks

Do tiny underground tremors provide clues that a big earthquake is coming? A new study suggests foreshocks are just like other small quakes, not helpful warning signs as previously thought.

East Rift Zone

Geothermal at the foot of Kilauea

Geothermal engineer Roland Horne discusses geothermal energy in the face of natural hazards and a way to tap the earth’s heat far from volcanoes in the future.

Lava lake

Understanding Kilauea: A different flavor of volcano

Geophysicist and volcanologist Paul Segall describes Hawaii's most active volcano and the science behind the latest eruptions.

Summit of Villarica volcano

Stanford scientists eavesdrop on volcanic rumblings to forecast eruptions

Sound waves generated by burbling lakes of lava atop some volcanoes point to greater odds of magmatic outbursts. This finding could provide advance warning to people who live near active volcanoes.

New map profiles induced earthquake risk for West Texas, New Mexico

A seismic stress map created by Stanford geophysicists can help predict which parts of West Texas and New Mexico may be at risk of fracking-induced earthquakes. The map could guide oil discovery efforts in the region.

Thwaites Glacier in Antarctica

Interacting Antarctic glaciers may cause faster melt and sea level contributions

Two of the most rapidly changing glaciers in Antarctica, which are leading contributors to sea-level rise, may behave as an interacting system rather than separate entities, according to a new analysis of radar data.

Small earthquakes at fracking sites may be early indicators of bigger tremors to come

Tiny tremors caused by hydraulic fracturing of natural gas near the surface could be early signs of stressful conditions deep underground that could destabilize faults and trigger larger earthquakes.

More frequent fires slow plant regrowth

Long-term effects of repeated fires on soils found to have significant impacts on carbon storage not previously considered in global greenhouse gas estimates.
