How Magma Climbs the Crustal Ladder Between Eruptions

The road cut seems rather dull and gray at first, but the tuff and pumice rocks hold the secrets of a volcano. Covered in...

‘Ring around bathtub’ at giant volcano field shows movement of subterranean...

The Laguna del Maule volcanic complex in Chile is a large, complicated and explosive landscape that, oddly, lacks the classic cone seen on many...

New way to estimate magma beneath Yellowstone supervolcano

Researchers at Washington State University and the University of Idaho have found a new way to estimate how fast magma is recharging beneath the...

Magma ocean may be responsible for the moon’s early magnetic field

Around four billion years ago, the Moon had a magnetic field that was about as strong as Earth's magnetic field is today. How the...

Catching mantle plumes by their magma tails

Hawaii's volcanos stand as silent sentinels. They guard the secret of how they formed, thousands of miles away from where the edges of tectonic...

Lavas in the lab could lead miners to new iron ore...

Geologists have discovered that some magmas split into two separate liquids, one of which is very rich in iron. Their findings can help to...

New study reveals the secret of magmas that produce South Africa’s...

South Africa's history and economy has been built on its rich natural treasures of a number of precious metals, stones and minerals. The country's mineral...

Chemical tipping point of magma determines explosive potential of volcanoes

Volcanic eruptions are the most spectacular expression of the processes acting in the interior of any active planet. Effusive eruptions consist of a gentle...

When magma prevents volcanic eruptions

A spectacular proof of our planet's activity, calderas are huge topographic depressions, similar to flat-bottomed craters, with a diameter of several tens of kilometres....

Moon’s crust underwent resurfacing after forming from magma ocean

The Earth's Moon had a rough start in life. Formed from a chunk of the Earth that was lopped off during a planetary collision,...

Magma held in ‘cold storage’ before giant volcano eruption

Long Valley, California, has long defined the "super-eruption." About 765,000 years ago, a pool of molten rock exploded into the sky. Within one nightmarish...

New magma pathways after giant lateral volcano collapses

Giant lateral collapses are huge landslides occurring at the flanks of a volcano. Giant lateral collapses are rather common events during the evolution of...

Magma chambers have a sponge-like structure

Supervolcanoes are superlative in every respect. The eruption of the Toba caldera in modern-day Indonesia approximately 74,000 years ago was so powerful that it...

Getting to the root of Iceland’s molten rock origins

New data reveal an unprecedented depiction of a region of partially molten rock deep within the Earth, which appears to be feeding material in...

Volcanic Crystals Give a New View of Magma

Volcanologists are gaining a new understanding of what's going on inside a shallow magma reservoir that lies below an active volcano and they're finding...

Deep magma reservoirs are key to volcanic ‘super-eruptions,’ new research suggests

New study shows the importance of large reservoirs in creating Earth's most powerful volcanic eruptions and explains why they are so rare Large reservoirs of...

New study documents aftermath of a supereruption, and expands size of...

The rare but spectacular eruptions of supervolcanoes can cause massive destruction and affect climate patterns on a global scale for decades - and a...

Deep mantle chemistry surprise: Carbon content not uniform

Even though carbon is one of the most-abundant elements on Earth, it is actually very difficult to determine how much of it exists below...

Modeling magma to find copper

Copper is an essential element of our society with main uses in the field of electricity and electronics. About 70% of the copper comes...

Cyclic change within magma reservoirs significantly affects the explosivity of volcanic...

A new study published in Geology uses pockets of melts trapped within crystals to understand the conditions occurring beneath volcanoes before explosive eruptions. Volcanologists...
