A new perspective on volcanic plumbing systems

Volcanic eruptions such as Mount St. Helens’ in 1980 show the explosiveness of magma moving through the Earth’s crust. Now geologists are excited about what uplifted granite bodies such as Yosemite’s El Capitan say about magma that freezes before it

Stalagmites from Iranian cave foretell grim future

Results from analysis of stalagmites in an Iranian cave, which include information during the last glacial and interglacial periods, showed that relief from the current dry spell across the interior of the Middle East is unlikely within the next 10,000

Falling sea levels caused volcanoes to overflow

A team of international scientists researching volcanoes have found new connections between the solid earth and the climate system. Climate evolution shows some regularities, which can be traced throughout long periods of earth’s history. One of them is that the

Bulges in volcanoes could predict eruptions

A team of researchers from UC have developed a new way of measuring the pressure inside volcanoes, and found that it can be a reliable indicator of future eruptions. Using a technique called ‘seismic noise interferometry’ combined with geophysical measurements,

Aerosols, climate change and Icelandic volcanic eruption

A spectacular six-month Icelandic lava field eruption could provide the crucial key for scientists to unlock the role aerosols play in climate change, through their interactions with clouds. An international team of climate scientists, led by the University of Exeter,

Volcanic eruptions triggered dawn of the dinosaurs

Huge pulses of volcanic activity are likely to have played a key role in triggering the end Triassic mass extinction, which set the scene for the rise and age of the dinosaurs, new Oxford University research has found. Researchers from

Curiosity rover finds clues to ancient Mars environment

NASA scientists have found a wide diversity of minerals in the initial samples of rocks collected by the Curiosity rover in the lowermost layers of Mount Sharp on Mars, suggesting that conditions changed in the water environments on the planet

Source of 1586 Sanriku, Japan, tsunami uncovered

A team of researchers re-examined historical evidence around the Pacific and discovered the origin of the tsunami that hit Sanriku, Japan in 1586—a mega-earthquake from the Aleutian Islands that broadly impacted the north Pacific. Until now, this was considered an

Why rocks flow slowly in Earth’s middle mantle

For decades, researchers have studied the interior mantle of the Earth using seismic waves from earthquakes. Now a recent study, led by Arizona State University’s School of Earth and Space Exploration Associate Professor Dan Shim, has re-created in the laboratory

Deep magma reservoirs are key to super-eruptions

Large reservoirs of magma stored deep in the Earth’s crust are key to producing some of the Earth’s most powerful volcanic eruptions, new research has shown. In a new study, an international team of scientists claim that the most powerful
