Machine Learning Highlights Ways to Improve Flood Mitigation

Aaron Sidder, freelance science writer by Aaron Sidder 18 October 202318 October 2023

New research shows that home flood insurance coverage is often a reactive purchase in response to flooding, while top-down policies that focus on community resilience may offer more robust protection.

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.
