The technique of heliospheric imaging could be valuable for future space weather operations.
Hazards & Disasters
Pollution over Southeast Asia May Threaten Ozone Health
Emissions of short-lived chlorine-based chemicals that deplete ozone are increasing worldwide. But over some regions of Asia, these chemicals may be on a fast track to the ozone layer.
Volcanic Woes May Have Contributed to Ancient Egypt’s Fall
Ice cores and ancient river records suggest that volcanic eruptions may have reduced the flow of the Nile River. Failures of the Nile floods that usually irrigated Egypt’s farms could have fed social unrest.
Probing Magma Reservoirs to Improve Volcano Forecasts
The roots of volcanoes remain enigmatic, largely because geophysical and petrological models remain rudimentary. Scientific drilling and exploration can help.
Polluted Lakes in Disguise
Clear lake water under highly polluted conditions might necessitate a rethink of water management policies and pollutant mitigation.
New Frontiers and Technologies in Submarine Volcanism Research
AGU Chapman Conference on Submarine Volcanism: New Approaches and Research Frontier; Hobart, Tasmania, Australia, 29 January to 3 February 2017
How to Trigger a Massive Earthquake
Humans may be to blame for California’s second-largest 20th century earthquake, and a team of seismologists has now proposed how that could have happened.
Storms May Have Produced Most Mediterranean “Tsunami” Deposits
A new analysis reveals that nearly all of the region’s sedimentary evidence ascribed to tsunamis, which dates back 4,500 years, corresponds to periods of heightened storminess.
How Earth’s Outer Radiation Belts Lose Their Electrons
A new analysis of three space storms reveals the mechanisms of particle loss from the Van Allen belts.
Sooty Bird Bellies Yield Insights into Historical Air Pollution
A new study mined museum collections to investigate just how sooty the air in the United States has been for the past 135 years.
