Forecasting Earthquake-Induced Floods

Katherine Kornei, Science Writer by Katherine Kornei 12 June 202312 June 2023

Surface-rupturing earthquakes can abruptly reroute rivers when fault scarps function like dams. Researchers have now successfully modeled such an event that occurred in New Zealand.

Dating the World’s Tallest Trees

Katherine Kornei, Science Writer by Katherine Kornei 27 April 202319 May 2023

Scientists analyzed more than 1.2 million trees to assemble chronologies of annually dated rings, which will inform fields ranging from climate science to seismology.

The increasing frequency and intensity of acute disasters are exposing more people to traumatizing events such as Hurricane Katrina, which devastated New Orleans communities and forced thousands of residents from their homes in 2005.

Asteroid Impacts Could Have Warmed Ancient Mars

Katherine Kornei, Science Writer by Katherine Kornei 17 April 202317 April 2023

Hydrogen released during large impacts might have boosted Mars’s surface temperature above freezing for thousands or even millions of years, enabling liquid water to flow over the Red Planet.
