The increasing frequency of once-in-a-decade agricultural and ecological drought has underscored the urgency of studying hydrological changes. A research team has analyzed the estimated changes in land water storage over the past 40 years by utilizing space geodetic observation technology and global hydrological change data. This innovative method has revealed a rapid depletion in global soil moisture, resulting in a significant amount of water flowing into the oceans, leading to a rise in sea levels. The research provides new insights into the driving factors behind the alarming reduction in terrestrial water storage and rise in sea levels.

When we think of earthquakes, we imagine sudden, violent shaking. But deep beneath the Earth's surface, some faults move in near silence. These slow, shuffling slips and their accompanying hum -- called tremors -- don't shake buildings or make headlines. But scientists believe they can serve as useful analogs of how major earthquakes begin and behave.

Using rock samples collected from the Wasatch Fault, geoscientists combined experiments and analysis with examinations of fault rock textures. The team's research revealed significant clues about the Wasatch Fault's earthquake risk. Researchers explain why properties of fault rocks and geologic events that occurred more than a billion years ago portend worrisome seismic activity for Utah's population center.

Analysing lava flows that solidified and then broke apart over a massive crack in the Earth's crust in Turkey has brought new insights into how continents move over time, improving our understanding of earthquake risks.

A new study has investigated the use of a new monitoring technique for early warning of a volcanic eruption. The research team compared the earthquake signals during two eruptions of Ontake Volcano in Japan, one of which was a small eruption and the other of which was explosive. From this, they were able to identify that shear-wave splitting parameters showed differences depending on the size of the eruption. The study proposes that the monitoring of this signal would provide a useful early warning of dangerous volcanic eruptions.

New research has revealed that a massive meteorite struck northwestern Scotland about 200 million years later than previously thought, in a discovery that not only rewrites Scotland's geological history but alters our understanding of the evolution of non-marine life on Earth.

On Jan. 1, 2024, a 7.5-magnitude earthquake struck the Noto Peninsula in Japan, resulting in extensive damage in the region caused by uplift, when the land rises due to shifting tectonic plates. The observed uplift, however, varied significantly, with some areas experiencing as much as a 5-meter rise of the ground surface. To better understand how the characteristics of the affected fault lines impact earthquake dynamics, researchers in Japan used recently developed simulations to make a detailed model of the fault. The findings could help develop models to simulate scenarios of different earthquakes and mitigate disasters in the future.

Scientists believe that the motion of Earth's continents through plate tectonics has been largely steady over millions of years. New research, however, suggests this drift can speed up or slow down over relatively short time periods.

What roils beneath the Earth's surface may feel a world away, but the activity can help forge land masses that dictate ocean circulation, climate patterns, and even animal activity and evolution. In fact, scientists believe that a plume of hot rocks that burst from the Earth's mantle millions of years ago could be an important part in the story of human evolution.
