Unearthing the Cause of Slow Seismic Waves in Subduction Zones
Researchers look to the fossil rock record to unearth the driving forces for variable seismic speed through subduction zones.
La vida después de una super erupción
Una vez que una erupción volcánica masiva termina, el sistema subyacente puede mantenerse activo por miles de años. Una nueva investigación vislumbra cómo funcionan los ciclos de super erupciones.
Supergreen Trees Can Signal Sites of Eruptions
Tree core chemistry can explain what happened before Mount Etna’s 2002 eruption and suggests that trees could play a role in rebuilding past eruptions.
A Simple Recipe for Making the First Continental Crust
Laboratory experiments serendipitously revealed a rock-forming process that might explain how the first continental crust formed on Earth—and possibly on Mars.
Seismology: A Promising Tool for Monitoring Permafrost
Passive seismic data from a station atop Germany’s highest peak reveal a 15-year record of permafrost degradation, suggesting that this technique could be used for long-term environmental monitoring.
Wind and Ocean Currents May Contribute to Mass Dolphin Strandings
Coastal wind patterns correlate with mass strandings of dolphins, suggesting that storm-induced upwelling could be influencing cetaceans’ behavior.
Forecasting Geohazards in the Age of Gas Hydrate Exploitation
A curious breath-like pattern exhibited by gas hydrates may help forecast hazards associated with extracting them from the seafloor.
An Explanation, at Last, for Mysterious “Zen Stones”
Laboratory experiments re-create the thin, icy pedestals that support some rocks in nature, revealing that sublimation plays a key role in the formation of these rare and beautiful structures.
New Tool Crafts Fast, Free Flood Maps for the Global South
A new online program can quickly map the outlines of past floods, allowing data-scarce countries to prepare for future disasters.
