A Hanging Glacial ‘Tooth’ Caused February’s Deadly Indian Flash Flood

In February, a massive avalanche tore through a mountain valley in the northern Indian state of Uttarakhand, causing flash flooding and mudslides. A new study has found that debris broke off a glacier above the valley and disintegrated so quickly that the resulting friction melted ice around it, causing the enormous,…Read more...

Washoe Lake, Slide, Mt. Rose, and Lake Tahoe

Just a quick shot taken from a plane a couple days ago, looking south from around 12,000 feet or so. We circled Lake Tahoe completely, finally coming into the Reno airport from the south—an approach I'm not sure I've been on in my several decades living in the area. [Author: Silver Fox]

Ancient tsunami could have wiped out Scottish cities today, study finds

Research maps the extent of the catastrophic Storegga tsunami 8,200 years ago for the first timeTowns and cities across Scotland would be devastated if the country’s coastline was hit by a tsunami of the kind that happened 8,200 years ago, according to an academics’ study.While about 370 miles of Scotland’s northern and eastern coastline were affected when the Storegga tsunami struck, the study suggests a modern-day disaster of the same magnitude would have worse consequences.

Permian Seafloor Gardens Of Glass

In Metazoa:Animal Minds and the Birth of Consciousness, author Peter Godfrey-Smith describes the Hexactinellida, a group of sponges that construct hard parts made of silicon dioxide as a support for its soft tissue. In an earlier post I had written briefly about amorphous varieties of silica. The Hexactinellidae's skeleton is made up of opal, denoted by the chemical formula SiO2.nH2O. Sponges put together their skeleton using a variety termed opal-A , the A indicating amorphous. Over geologic ...

An Ancient Supervolcano May Have Zapped the Ozone Layer, Exposing Early Humans to Intense Sunburns

The Toba super-eruption of some 74,000 years ago has long intrigued scientists, who remain uncertain about how the event affected humans living at the time. Now, a team of researchers suggest that the real damage from Toba came from on high, in the form of a depleted ozone layer induced by a massive release of sulfur…Read more...

Massive fossil find in California includes mastodon, petrified forest

A ranger working for a San Francisco water utility discovers a massive petrified forest and its ancient residents. The forest dates from the Miocene era 10 million years ago.Mastodons, horses, and rhinoceroses lived there.As we go about our daily lives, it's easy to forget that the places we find ourselves weren't always the way they are now. While people driving down Highway 163 in Utah's Monument Valley may be awestruck by the towering red rocks, they may not think about what those rocks sign...

Tarantulas: How 120-million-year-old creatures conquered the globe

Scary-looking tarantulas actually prefer to keep to themselves and stay in their burrows. Their sedentary nature makes a puzzle of their presence in so many places around the world.Researchers discover that this is because they've been around a very long time and rode drifting continental land masses to their contemporary positions.Whenever a movie script calls for the protagonist to be menaced by a spider, central casting typically places a call to a tarantula wrangler. Tarantulas, or therapho...

How scientists actually collect magma samples in a bucket

Via US Geological Survey: This video clip shows HVO geologist Tim Orr sampling lava from an active pāhoehoe breakout on the episode 61g lava flow. The chemistry of these lava samples provides information on the magma plumbing system. Sampling has been a regular part of monitoring Kīlauea Volcano's ongoing Pu'u 'Ō'ō eruption.

‘Hidden’ magma pools under volcanoes may pose alarming eruption threats

The study analyzed magma collected from a 2009 incident in which geothermal drillers encountered magma that geophysical surveys failed to detect.Currently, magma imaging technology can't accurately detect magma pools under a certain size.Hidden magma pools pose safety concerns because magma from other sources might combine with the hidden magma, which could trigger unexpectedly explosive eruptions.In 2009, scientists with the Deep Drilling Project were drilling a mile-deep borehole into Iceland'...

Remnants of an ancient planet buried inside the Earth may be the cause of a weak spot in the magnetic field

An artist's depiction of Earth's magnetic field, which protects the planet from solar radiation. NASA Earth's magnetic field, which protects it from solar radiation, has a weak spot that's expanding. This weak spot may be caused by pieces of an ancient planet that hit Earth and sank into the mantle. The growing "dent" in the magnetic field can cause malfunctions in satellites and spacecraft.

A new warning sign to predict volcanic eruptions?

A recent study used data collected by NASA satellites to conduct a statistical analysis of surface temperatures near volcanoes that erupted from 2002 to 2019.The results showed that surface temperatures near volcanoes gradually increased in the months and years prior to eruptions.The method was able to detect potential eruptions that were not anticipated by other volcano monitoring methods, such as eruptions in Japan in 2014 and Chile in 2015. How can modern technology help warn us of impending...

Terrawatch: cities that change the shape of the planet

The weight of buildings in dense urban areas can lead to subsidence, with effects particularly marked by the coastIt’s well known that ice sheets are heavy enough to bend the underlying rocks, but what about cities? Are some cities capable of reshaping the bit of planet they sit on?By 2050 around 70% of Earth’s population are projected to live in cities.

Second Fissure Opens Up At Fagradalsfjall (UPDATE - THIRD FISSURE ERUPTS)

REYKJANES PENINSULA, ICELAND - An approximately 200 meter long fissure has opened up to the SW of the first eruptive vents at Fagradalsfjall at approximately noon Iceland time on April 5th. The fissure opened up some 200 meters from a rescue and aid camp that was set up nearby, which was quickly dismantled and moved. New fissure outbreak at Fagradalsfjall. The new fissure can be seen below in relation to the main vent, with lave spilling down a valley to the ENE.  New fissure on the lowe...

Rain, caves, and miracles: New study connects weather to ancient tales

Ancient climate patterns can be determined by examining the ratios of various isotopes.Isotopic signatures found in Italian cave stalagmites suggest that the Sixth Century was wetter than usual.The study provides a partial explanation for the origin of stories about saints performing water miracles. Ancient and near ancient records are often less than trustworthy. Even if you ignore the parts with reports of sea monsters or ants that mine gold , certain events often seem exaggerated. If we tr...

Did Earth eat the protoplanet it crashed into long ago?

Many experts believe that the Moon was formed when a protoplanet named Theia crashed into the Earth 4.5 billion years ago.One flaw in the theory has been that there's no remaining sign of Theia.New research suggests that Theia's mantle was subsumed by Earth and that large anomalous blogs of rock deep within the Earth are its remains. They're called "large low-shear-velocity provinces" (LLSVPs), and they're large anomalous globs of, well, some kind of rock deep inside the Earth. There's one unde...

Lightning may have provided a key mineral for early life on Earth

A chance discovery in suburban Illinois may change how we understand the dawn of life. Among other things, life needs water-soluble phosphorus, which was hard to come by 3.5 billion years back. This finding may imply that life has more opportunities to begin on other worlds than previously supposed. Even the youngest child often wonders where they came from. For many scientists, a group of people known for retaining their childlike wonder, the question naturally evolves to asking how life its...

Humans still similar to first animals without heads, arms or skeletons

A new study finds genetic links between early oceanic animals and humans. The animals studied had no heads, skeletons, legs or arms.The creatures were from the Ediacaran era, living about 555 million years ago. As complex as modern humans can get, they still retain some features of the earliest animals on Earth, found new research. We are not as different as we might think from strange prehistoric organisms that didn't have any heads, arms, legs or skeletons.A study from UC Riverside identified...
