The Andes Mountains are much taller than plate tectonic theories predict they should be, a fact that has puzzled geologists for decades. Mountain-building models tend to focus on the deep-seated compressional forces that occur when tectonic plates collide and send rocks skyward. A new study demonstrates how modern top-down models that account for climate-related factors … Study combines climatic, tectonic models to explain Andean conundrum

A new study has found that the minerology of the rocks that a meteorite hits, rather than the size of the impact, determines how deadly an impact it will have.

The noise created by the Earth’s movements has been used to build up a detailed picture of the geological conditions beneath the Greenland Ice Sheet and the impact on ice flow, in new research.  The team studied Rayleigh waves — seismic waves generated by movements such as earthquakes — to produce high-resolution images of the … Using the Earth’s noise to see beneath the Greenland ice sheet

Insights into how the West Antarctic Ice Sheet responded to a warmer climate millions of years ago could improve predictions of its future.

The San Andreas and San Jacinto faults have ruptured simultaneously at least three times in the past 2,000 years, most recently in 1812, according to a new study by geologists.

New research shows that physics measurements of just a small portion of reef can be used to assess the health of an entire reef system. The findings may help scientists grasp how these important ecosystems will respond to a changing climate.

Rising sea levels are already impacting coastal residents and aggravating existing coastal hazards, such as flooding during high tides and storm surges. New research indicates that future sea-level rise will also have impacts on the heights of future tsunamis. Title: New research makes waves tackling the future of tsunami monitoring and modelingSourced From: www.sciencedaily.com/releases/2021/12/211208090014.htmPublished Date: … New research makes waves tackling the future of tsunami monitoring and modeling

A large earthquake off the coast of south-central Chile in 1737 may have caused a substantial tsunami that was absent from historical records. Historical records are used to predict how often tsunamis are likely to occur in a region in the future. Until now, it was previously believed that tsunami-causing earthquakes had occurred in this … Previously unrecorded Chilean tsunami identified

At the crushing pressures of Earth‘s lower mantle (670-2890 km deep), electrons were long ago predicted to swap dance partners, an effect that has escaped geophysical detection for decades until now. The signature is not global but localised to rock that once laid beneath the ocean floor and now dives into the deepest rocky mantle. … Geophysicists detect electron dance deep inside the Earth, with a Twist

Iron is an essential nutrient that almost all life requires to grow and thrive. Iron’s importance goes all the way back to the formation of the planet Earth, where the amount of iron in the Earth’s rocky mantle was ‘set’ by the conditions under which the planet formed and went on to have major ramifications … Iron integral to the development of life on Earth – and the possibility of life on other planets
