According to physics, seismic waves from earthquakes should travel in a four-leaf clover pattern, but in the real world they behave more like ripples in a pond. New research has found the pattern hidden among low-frequency seismic waves, the kind that can topple buildings. The study looked at small earthquakes in northern Oklahoma and could … Seismic shockwave pattern may be redirecting earthquake damage

Climate scientists identify abrupt transitions in climate records that may have been caused by the climate system crossing a tipping point. They devised a statistical method to determine whether these transitions are simply noise or evidence of a more significant change. Their method is less error-prone than previous methods, since it doesn’t rely on human … Climate changed abruptly at tipping points in past

A team of scientists has identified an additional force that likely contributed to a mass extinction event 250 million years ago. Its analysis of minerals in southern China indicate that volcano eruptions produced a ‘volcanic winter’ that drastically lowered earth’s temperatures — a change that added to the environmental effects resulting from other phenomena at … ‘Volcanic winter’ likely contributed to ecological catastrophe 250 million years ago

New research reveals that after its initial formation 100 million years ago, the Sierra Nevada ‘died’ during volcanic eruptions that blasted lava across much of the American West 40 million to 20 million years ago. Then, tens of millions of years later, the Sierra Nevada mountain range as we know it today was ‘reborn.’ Title: … Sierra Nevada range should celebrate two birthdays

Hydrocarbons, which are an essential component of crude oil and natural gas, form under pressure and high temperatures in the deep ocean floor. In the Guaymas Basin in the Gulf of California, researchers have detected hydrocarbon gas patterns that could not have been generated by known formation pathways. In their study they describe a new … Hydrocarbon gas: Explanation for unusual isotope patterns

New observations of the atomic structure of iron reveal it undergoes ‘twinning’ under extreme stress and pressure.

The mechanism behind one of the first stages of coal creation may not be what we thought it was, according to a team of researchers who found that microbes were responsible for coal formation and production of methane in these areas, which has implications for methane fuel recovery from some coal fields. Title: Coal creation … Coal creation mechanism uncovered

Geophysicists can use a new model to explain the behavior of a tectonic plate sinking into a subduction zone in the Earth’s mantle: the plate becomes weak and thus more deformable when mineral grains on its underside are shrunk in size. Title: Crushed resistance: Tectonic plate sinking into a subduction zoneSourced From: www.sciencedaily.com/releases/2021/11/211111130240.htmPublished Date: Thu, … Crushed resistance: Tectonic plate sinking into a subduction zone

When tectonic plates sink into the Earth they look like slinky snakes! That’s according to a study published in Nature, which helps answer a long standing question about what happens to tectonic plates when they sink – or subduct – into the Earth’s interior. The process helps drive plate tectonics. Title: Fate of sinking tectonic … Fate of sinking tectonic plates is revealed
