Rocks stretch, break, and flow, depending on how and under which conditions they are loaded. A new formulation to better capture Earth’s rheology is explored in the context of plate thickness.Read More »Biogeosciences
Levels of dissolved trace and heavy metals, which can be toxic, are highly variable across the river basin, concentrating in urban areas with high pollution but diluted by inflow from tributaries.Read More »Geochemistry, Mineralogy, Volcanology
Subduction zones with a low dipping angle and thick sediments can produce giant earthquakes; this finding lets researchers estimate worst-case scenarios for coastlines around the world.Read More »
Impact and turbulence models for river tremor are adapted and combined into a model that predicts the amplitude and frequency content of volcanic eruption tremor.Read More »Geochemistry, Mineralogy, Volcanology
Meteorite NWA 11004 contains evidence of melting preceding an impact dated to 4546±36 Ma. Short lived radioactive decay had already heated the parent body of this meteorite before the impact.Read More »Geochemistry, Mineralogy, Volcanology
More than 70 passive sensors on Mount Etna have captured the first radon measurements in volcanic plumes and show that radon could affect people around volcanoes.Read More »Geology & Geophysics
Earthquake hazard calculations for California’s coast are refined with a view of precariously balanced rocks that would have fallen if the largest predicted shaking happened in the past 20,000 years.Read More »
At Kīlauea Volcano, scientists are using unoccupied aircraft to monitor the new water lake, a possible harbinger of explosive activity, that formed after the volcano’s 2018 eruption.Read More »Geochemistry, Mineralogy, Volcanology
The construction industry is one of the world’s largest emitters of carbon dioxide. Whether it can reduce those emissions depends on replacing its most common building material.Read More »Geology & Geophysics
A new study that combines constraints from the 2015 Gorkha earthquake, forward models of deforming crust, and thermochronology data gives new insights into the structure of the Himalaya.Read More »
