Natural hazards
Colombian City Pioneers Path to “Early Warnings for All”
Medellín alerts citizens to floods, landslides, fires, lightning, and poor air quality.
Forecasting Earthquake-Induced Floods
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.
Ancient Victims of Vesuvius May Have Baked in a Cloud of Ash
Debate still swirls around what killed ancient Romans during the 79 CE eruption. A study of wood charred by the event suggests a brief, but searing, flow of volcanic gas and debris.
A Common Language for Reporting Earthquake Intensities
Scientists are working together to establish a standardized international scale for measuring and reporting the intensities and impacts of earthquake shaking.
Envisioning a Near-Surface Geophysics Center for Convergent Science
A recent effort identified how a proposed near-surface geophysics center integrating research and teaching could address critical challenges and promote community engagement and cultural change.
Observing a Seismic Cycle at Sea
Scientists organized a trio of expeditions to document the buildup of stress leading to a large earthquake on a seafloor fault, developing innovations for successful seagoing research in the process.
How Hail Hazards Are Changing Around the Mediterranean
A new method for studying hailstorms from space offers more consistent and more complete views of how and where hail forms, and how climate change might influence hail’s impacts in the future.
Engineering with Nature to Face Down Hurricane Hazards
Natural and engineered, nature-based structures offer promise for storm-related disaster risk reduction and flood mitigation, as long as researchers can adequately monitor and study them.
A Better Operational Lava Flow Model
By segmenting the vertical structure of a lava flow, the Lava2d model provides more realism to operational lava forecasts.
