A new simulation of space-weather driven geoelectric fields at the land/sea conductivity boundary shows how these fields are magnified by both coastal effects and inhomogeneous land conductivity.
Hazards & Disasters
Social Media Helps Reveal Cause of 2018 Indonesian Tsunami
Videos from Twitter and YouTube helped scientists tease out the physical mechanisms that generated the large tsunami in Palu Bay after a magnitude 7.5 earthquake.
Detecting Earth’s Natural Hazards High Up in the Sky
Signals in the ionosphere contain information about the source and scale of natural hazards occurring on Earth’s surface that could be used for monitoring and mitigation.
The Ticking Time Bomb of Arctic Permafrost
Arctic infrastructure is under threat from thawing permafrost.
Did Ozone Loss Cause the End Devonian Mass Extinction?
Ozone loss, perhaps as a consequence of a warming climate, may have been responsible for a catastrophic loss of biodiversity.
Modeling Fluid Migration in Subduction Zones
Scientists from different disciplines are working together to identify common challenges in and techniques for modeling fluid migration associated with subduction zone processes.

Otherwise, fossil fuel emissions will return to normal.
The Ability of Pyroclastic Flows to Generate Tsunamis
Lab experiments of fluidized granular flows entering the water shed light on the dynamics of tsunami generation by fast-moving, pyroclastic density currents at volcanic islands or coastal volcanoes.
Armagedón a 10,000 A.C.
Fragmentos de un cometa probablemente golpearon la Tierra hace 12,800 años, y una pequeña aldea del Paleolítico en Siria podría haber sufrido el impacto.
