Estimating Lake Evaporation Just Got Easier
A new method standardizes freshwater lake measurements and shows they are losing a fifth of their inflow to evaporation.
Layered Zone Beneath Coral Sea Suggests Ancient Magma Ocean
Scientists studying South Pacific earthquakes suggest that an ultralow-velocity zone at the core-mantle boundary may be a remnant of a molten early Earth.
Sensing Iceland’s Most Active Volcano with a “Buried Hair”
Distributed acoustic sensing offered researchers a means to measure ground deformation from atop ice-clad Grímsvötn volcano with unprecedented spatial and temporal resolutions.
A Monsoon-Filled Reservoir Might Have Nudged a Fault to Fail
New research examines whether a sudden increase in water loading in Pakistan’s Mangla Dam might have been connected to the 2019 New Mirpur earthquake.
Geoscientists Can Help Reduce the Threat of Nuclear Weapons
A nuclear war would claim many lives from its direct impacts and cause rapid climate change that would further imperil humanity. Scientists can help shape policies to put us on a safer path.
When Deep Learning Meets Geophysics
Traditional physical models are no longer the only foundational tools for processing geophysical data; “big data” help to reveal the laws of geophysics from new angles with exciting results so far.
Gas-Rich, Transcrustal Magma Storage in the Main Ethiopian Rift
Increments of melt trapped in crystals reveal upper crustal magmas in the Main Ethiopian Rift are rich in water and other volatiles, leading to extensive diffuse degassing and hydrothermal systems.
Taro Takahashi (1930–2019)
This giant in geochemistry also pioneered early high-pressure, high-temperature studies that launched the field of mineral physics.
Understanding High-Energy Physics in Earth’s Atmosphere
Thunderstorms present a variety of hazards, including emissions of ionizing radiation. An international group of scientists met at an Armenian observatory to share their findings.
