Researchers showed that the 1995 Kobe (Hyogo-ken Nanbu) earthquake, which struck southern Hyogo Prefecture, may have been triggered by deep underground flooding beneath Arima Hot Springs. By analyzing the stable isotope ratios of hydrogen and oxygen as well as chloride ions in Arima hot spring water over several decades, the researchers have uncovered a likely connection between the earthquake and water originating from the subducting Philippine Sea Plate.

Researchers have discovered inorganic nanostructures surrounding deep-ocean hydrothermal vents that are strikingly similar to molecules that make life as we know it possible. These nanostructures are self-organized and act as selective ion channels, which create energy that can be harnessed in the form of electricity. The findings impact not only our understanding of how life began, but can also be applied to industrial blue-energy harvesting.

A mysterious type of iron-rich magma entombed within extinct volcanoes is likely abundant with rare earth elements and could offer a new way to source these in-demand metals, according to new research. Rare earth elements are found in smartphones, flat screen TVs, magnets, and even trains and missiles. They are also vital to the development of electric vehicles and renewable energy technologies such as wind turbines.

A new study offers the most detailed glimpse yet into how Earth's surface temperature has changed over the past 485 million years. The data show that Earth has been and can be warmer than today -- but humans and animals cannot adapt fast enough to keep up with human-caused climate change.

Some of the most dramatic climatic events in our planet's history are 'Snowball Earth' events that happened hundreds of millions of years ago, when almost the entire planet was encased in ice up to 0.6 miles thick. New research provides a more complete picture for how the last Snowball Earth event ended, and suggests why it preceded a dramatic expansion of life on Earth, including the emergence of the first animals.

Understanding the relationship between plasticity of muddy soil and earth pressure can be crucial to maintaining tunnel stability and predicting ground behavior during earth pressure balance (EPB) shield tunnelling, a common underground excavation method. Researchers developed small-scale model experimentation combined with moving particle simulation-based computer-aided engineering analysis that reliably predicted soil's plasticity and its correlating factors without having to deal with the cost and time of on-ground field analysis.

A landslide in a remote part of Greenland caused a 200 meter (650 foot) mega-tsunami that sloshed back and forth across a fjord for nine days, generating vibrations throughout Earth, according to a new study. The study concluded that this movement of water was the cause of a mysterious, global seismic signal that lasted for nine days and puzzled seismologists in September 2023.

Amethyst is a violet variety of quartz which has been used as a gemstone for many centuries and is a key economic resource in northern Uruguay. Geodes are hollow rock formations often with quartz crystals, such as amethyst, inside. Amethyst geodes in Uruguay have been found in cooled lava flows, which date from the original breakup of the supercontinent Gondwana around 134 million years ago. However, their formation has remained a mystery.
