Mass extinction events are sometimes portrayed in illustrations of volcanic eruptions causing widespread destruction.
By meticulously examining sediments in China’s Yellow River, a Swedish-Chinese research group are showing that the history of tectonic and climate evolution on Earth may need to be rewritten. Their findings are published today in the highly reputed journal Nature Communications.
Berkeley geologists have uncovered compelling evidence that an asteroid impact on Earth 66 million years ago accelerated the eruptions of volcanoes in India for hundreds of thousands of years, and that together these planet-wide catastrophes caused the extinction of many land and marine animals, including the dinosaurs.
There have been many estimates for when the earth’s inner core was formed, but scientists from the University of Liverpool have used new data which indicates that the Earth’s inner core was formed 1 – 1.5 billion years ago as it “froze” from the surrounding molten iron outer core.
A new study shows that iron-bearing rocks that formed at the ocean floor 3.2 billion years ago carry unmistakable evidence of oxygen.
Major volcanic eruptions can have a significant effect on the flow of the biggest rivers around the world, research shows.
A pre-historical sudden collapse of one of the tallest and most active oceanic volcanoes on Earth — Fogo, in the Cape Verde Islands – triggered a mega-tsunami with waves impacting 220 metres (721 feet) above present sea level resulting in catastrophic consequences, according to a new University of Bristol study.
Scientists at the University of Birmingham have discovered evidence of carbonaceous aerosols – organic dust – transported from Asia and deposited in the Arctic over the last 450 years, according to research published in the journal Nature Scientific Reports.
Earth’s biosphere witnessed its greatest ecological catastrophe in the latest Permian, dated to about 251.9 million years ago.
Scientists have discovered the world’s longest known chain of continental volcanoes, running 2,000 kilometres across Australia, from the Whitsundays in North Queensland to near Melbourne in central Victoria.
Researchers at the University of Gothenburg have found traces of two enormous meteorite impacts in the Swedish county of Jämtland, a twin strike that occurred around 460 million years ago.
An international team of researchers, including scientists from the University of Cambridge, has discovered unique ‘graffiti’ on the walls of a cave in central China, which describes the effects drought had on the local population over the past 500 years.
In June, 1991, Mount Pinatubo in the Philippines exploded, blasting millions of tons of ash and gas over 20 miles high – deep into the stratosphere, a stable layer of our atmosphere above most of the clouds and weather.
Drone footage captures the beauty of one of the world’s largest caves, containing dense jungles, immense cliffs and its own climate.
At the end of the Pleistocene period, approximately 12,800 years ago — give or take a few centuries — a cosmic impact triggered an abrupt cooling episode that earth scientists refer to as the Younger Dryas.
The discovery of a fiber-reinforced, concrete-like rock formed in the depths of a dormant supervolcano could help explain the unusual ground swelling that led to the evacuation of an Italian port city and inspire durable building materials in the future, Stanford scientists say.
Two thousand years ago, Norway produced iron in significant quantities. Much of it was exported both southward and northward from Trøndelag in central Norway.
Researchers have found that parts of the western Solomon Islands, a region thought to be free of large earthquakes until an 8.1 magnitude quake devastated the area in 2007, have a long history of big seismic events.
Gas and oil seeps have been part of religious and cultural practices for thousands of years.
Geological knowledge is essential for the sustainable development of a “smart city” — one that harmonizes with the geology of its territory.
The Campanian Ignimbrite (CI) eruption in Italy 40,000 years ago was one of the largest volcanic cataclysms in Europe and injected a significant amount of sulfur-dioxide (SO2) into the stratosphere.
Hidden magnetic messages contained within ancient meteorites are providing a unique window into the processes that shaped our solar system, and may give a sneak preview of the fate of the Earth’s core as it continues to freeze.
