Newswise: Volcanic eruption may explain recent purple sunrises

Volcanic eruption may explain recent purple sunrises

University of Colorado Boulder

Photographers and others with a keen eye have noticed that sunrises and sunsets have become a lot more purple in the U.S. New measurements from a high-altitude balloon could explain why.

Jurassic world of volcanoes found in central Australia

University of Adelaide

An international team of subsurface explorers from the University of Adelaide in Australia and the University of Aberdeen in Scotland have uncovered a previously undescribed ‘Jurassic World’ of around 100 ancient volcanoes buried deep within the Cooper-Eromanga Basins of central Australia.

Careful analysis of volcano’s plumbing system may give tips on pending eruptions

Penn State Institute for CyberScience

A volcano will not send out an official invitation when it’s ready to erupt, but a team of researchers suggest that scientists who listen and watch carefully may be able to pick up signs that an eruption is about to happen. In a study of Hawaii's Kīlauea volcano, the researchers reported that pressure changes in the volcano’s summit reservoirs helped explain the number of earthquakes — or seismicity — in the upper East Rift Zone. This zone is a highly active region where several eruptions have occurred over the last few decades, including a spectacular one in 2018.

Chaos Theory Produces Map for Predicting the Paths of Particles Emitted Into the Atmosphere

American Institute of Physics (AIP)

Floating air particles following disasters and other geological events can have a lasting impact on life on Earth, and a new model drawing on chaos theory looks to help predict how these particles move, with an eye toward applications for geoengineering. Using available wind data, Tímea Haszpra developed a model for following particles as they travel around the globe. Using it, she has generated maps that can be used to predict how particles will be dispersed above the world.

Water drives explosive eruptions; here’s why magmas are wetter than we thought

Washington University in St. Louis

Volatile elements in magma, primarily water, drive explosive volcanic eruptions. The tricky part is determining just how much volatile content was present before the eruption took place. This is especially difficult when the only evidence scientists have to go on is the end product after all the volatiles have been lost.

Aftershocks of 1959 earthquake rocked Yellowstone in 2017-18

University of Utah

A swarm of more than 3,000 small earthquakes in the Maple Creek area (in Yellowstone National Park but outside of the Yellowstone volcano caldera) between June 2017 and March 2018 are, at least in part, aftershocks of the 1959 quake.
