Tiny earthquakes reveal hidden faults under Northern California

Phys.org: Earth science - Thu, 01/15/2026 - 19:00

By tracking swarms of very small earthquakes, seismologists are getting a new picture of the complex region where the San Andreas fault meets the Cascadia subduction zone, an area that could give rise to devastating major earthquakes.

Collapse of the Tang dynasty: Climate change likely played a role

Phys.org: Earth science - Thu, 01/15/2026 - 17:19

Environmental phenomena and their consequences can disrupt social structures and destabilize political systems. An interdisciplinary research team demonstrated this using the example of the late Tang dynasty in medieval China.

Large parts of the tropics overlooked in environmental research, study says

Phys.org: Earth science - Thu, 01/15/2026 - 16:03

Environmental research in the tropics is heavily skewed, according to a comprehensive study led by Umeå University. Humid lowland forest ecosystems receive a disproportionate amount of attention, while colder and drier regions that are more affected by climate change are severely underrepresented.

Earth system models overestimate river flow increases, research reveals

Phys.org: Earth science - Thu, 01/15/2026 - 14:50

Understanding how water moves through the Earth system is fundamental to predicting climate impacts and ensuring sustainable water management. Yet despite decades of research, uncertainties persist regarding how global precipitation is partitioned into evapotranspiration and river flow—the two dominant pathways by which water returns from land to the atmosphere and oceans.

Utah's other Great Salt Lake is underground, ancient, deep....and fresh

Phys.org: Earth science - Thu, 01/15/2026 - 10:36

Under the Great Salt Lake playa lies a potentially vast reservoir of pressurized freshwater that has accumulated over thousands of years from mountain-derived snowmelt, according to new research from University of Utah geoscientists. This groundwater occupies the pore spaces in sediments that fill the basin west of the Wasatch Mountains and below a 30-foot-thick salty layer.

Ocean impacts nearly double economic cost of climate change, study finds

Phys.org: Earth science - Thu, 01/15/2026 - 10:00

For the first time, a study by researchers at Scripps Institution of Oceanography at the University of California, San Diego integrates climate-related damages to the ocean into the social cost of carbon—a measure of economic harm caused by greenhouse gas emissions.

Increased deciduous tree dominance reduces wildfire carbon losses in boreal forests, study shows

Phys.org: Earth science - Thu, 01/15/2026 - 10:00

As climate change drives more frequent and severe wildfires across boreal forests in Alaska and northwestern Canada, scientists are asking a critical question: Will these ecosystems continue to store carbon or become a growing source of carbon emissions?

Rocks and rolls: The computational infrastructure of earthquakes and physics of planetary science

Phys.org: Earth science - Wed, 01/14/2026 - 19:49

Sometimes to truly study something up close, you have to take a step back. That's what Andrea Donnellan does. An expert in Earth sciences and seismology, she gets much of her data from a bird's-eye view, studying the planet's surface from the air and space, using the data to make discoveries and deepen understanding about earthquakes and other geological processes.

AI sheds light on hard-to-study ocean currents

Phys.org: Earth science - Wed, 01/14/2026 - 19:47

The Indonesian Throughflow carries both warm water and fresh water from the Pacific into the Indian Ocean. As the only low-latitude current that connects the two bodies of water, it plays a key role in ocean circulation and sea surface temperature worldwide.
