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.

More Clustered Clouds Amplify Tropical Rainfall Extremes
Both satellite observations and model simulations reveal that more aggregated convection amplifies the increase in extreme rainfall events on a year-to-year basis.
Eruption Seismic Tremor Modeled as a Fluvial Process
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.
The Ocean-Land Connection of Droughts
Around 16 percent of large-scale droughts over land originate above the ocean and these types of droughts are more extensive and severe than droughts that originate over land.
Traces of Impacts on Warm Planetesimals Early in Solar System
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.
Smart Water Metering Need Not Compromise People’s Privacy
Scientists have devised a way of preserving privacy for smart water metering users while also providing water suppliers with information they can use to improve the efficiency of water services.
Radon Enrichment in the Volcanic Plume of Mount Etna
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.
Earthquake Hazard Hanging in the Balance
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.
The Importance of Solar Lyman-alpha Emissions for Space Weather
Lyman-alpha emissions convey a major part of the solar-flare photon energy reaching Earth and play a significant role in flare-driven enhancements of ionospheric conductivity.
The Restless Geomagnetic Field Over the Past 70,000 Years
Detailed paleomagnetic records from Black Sea sediments reveal intricate changes in the field during geomagnetic excursions.
