A decade-long research collaboration has revealed that the split between Africa and North America roughly 200 million years ago was more drawn out than previously thought.
Science Updates
Slipping and Locking in Earth’s Earthquake Factories
Geodetic observations collected during back-to-back decadal research campaigns have revealed crucial new insights into the start–stop and slow-motion behavior of subduction zones.
Deep Submarine Fresh Water: A New Resource for Volcanic Islands?
The discovery of large freshwater reservoirs off Hawaii suggests that other volcanic islands may have similar resources, which could help meet water demands amid population growth and climate change.
Improving Models for Solar Climate Intervention Research
Modern climate models were designed to simulate natural systems and changes mainly due to atmospheric carbon dioxide, rather than to predict effects of deliberate climate interventions.
Discerning Structure and Seismic Hazards in the Sikkim Himalayas
A dense seismic network in operation since 2019 will provide new insights into the tectonics of seismically active Himalayan regions.
Measuring Ambient Ocean Sound During the COVID-19 Pandemic
An expanded nonmilitary hydrophone network provides new opportunities to understand the variability and trends of ocean sound and the effects of sound on marine organisms.
Improving Access to Paleoclimate Data
Paleoclimate databases are powerful tools for improving climate models. The recent work of speleothem researchers offers lessons on creating a lasting database and fostering the needed mindset.
Advances in Satellite Data for Wildfire Smoke Forecasting
Observations from the newest geostationary Earth-observing satellites are offering valuable views of fire progression and smoke plume development and helping simulate impacts from large wildfires.
Assessing Social Equity in Disasters
Natural hazard impacts and resources allocated for risk reduction and disaster recovery are often inequitably distributed. New research is developing and applying methods to measure these inequities.
Amateur Radio Operators Help Fill Earthquake Donut Holes
Ham radio networks gear up to provide real-time, on-the-ground information about earthquake shaking and damage when other communication pathways are knocked out of commission.
