Rice University and Georgia Tech scientists use data from ancient coral to build a record of temperatures in the tropical Pacific Ocean over the last millennium. The data question previous links between volcanic eruptions and El Niño events.
New Zealand's largest fault is a jumble of mixed-up rocks of all shapes, sizes, compositions and origins. According to research from a global team of scientists, this motley mixture could help explain why the fault generates slow-motion earthquakes known as 'slow slip events' as well as destructive, tsunami-generating tremors.
An international team of scientists has for the first time identified the conditions deep below the Earth's surface that lead to the triggering of so-called 'slow motion' earthquakes.
In a new study in the AGU journal Geophysical Research Letters, scientists from the University of California, Irvine and NASA's Jet Propulsion Laboratory describe Greenland's loss of 600 billion tons of ice in the summer of 2019, raising global sea levels by 2.2 millimeters in a short time.
Researchers say they have identified the origins of an unusual fault that probably magnified the catastrophic 2011 Japan tsunami.
A trio of studies are the latest developments in a paradigm shift that could change how Earth history is understood. They support an assertion by a Scripps Institution of Oceanography geophysicist that a once-liquid portion of the lower mantle, rather than the core, could have exceeded the thresholds needed to create Earth's magnetic field during its early history.
Scientists have developed a new computational technique that could lead to fast, finely detailed brain imaging with a compact device that uses only sound waves.
High-frequency vibrations are some of the most damaging ground movements produced by earthquakes, and Brown University researchers have a new theory about how they're produced.
In many coastal zones and gorges, unstable cliffs often fail when the foundation rock beneath them is crushed. Large water waves can be created, threatening human safety. In this week's Physics of Fluids, scientists reveal the mechanism by which these cliffs collapse, and how large, tsunami-like waves are created. Few experimental studies of this phenomenon have been carried out, so this work represents valuable new data that can be used to protect from impending disaster.
Geologists from Wits University in Johannesburg, South Africa, have come up with an original explanation of how nature may produce an intriguing class of magmatic rocks that are made up of only one type of mineral.
