Japanese student discovers new crustacean species in deep sea hydrothermal vent

A new species of microcrustacean (Stygiopontius ) was collected from a submarine hot spring (hydrothermal vent) of a volcanic seamount (Myojin-sho caldera) in the...

Volcanic hazard scenarios: Mount Taranaki, New Zealand

Over the last 5000 years, Mount Taranaki volcano, located in the westernmost part of New Zealand's North Island, produced at least 16 Plinian-scale explosive...

Ample warning of supervolcano eruptions likely, experts say

Concern over the potential imminent eruptions of Earth's supervolcanoes, like Taupo in New Zealand or Yellowstone in the United States, may be quelled by...

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...

Scientists decipher the magma bodies under Yellowstone

Using supercomputer modeling, University of Oregon scientists have unveiled a new explanation for the geology underlying recent seismic imaging of magma bodies below Yellowstone...

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...

Great magma erup­tions had two sources

Research at Finnish Museum of Natural History may explain controversies related to great magma eruptions. The modern continents were formed when Pangea broke into pieces...

Did highest known sea levels create the iconic shape of Mount...

The iconic cone-like structure of Mount Etna could have been created after water levels in the Mediterranean Sea rose following an extended period of...

Detecting volcanic eruptions

To borrow from a philosophical thought experiment: If a volcano erupts in a remote part of the world and no one hears it, does...

Understanding the Earth under Hawaii

In the 1960s, some 50 years after German researcher Alfred Wegener proposed his continental drift hypothesis, the theory of plate tectonics gave scientists a...

Wider coverage of satellite data better detects magma supply to volcanoes

Using satellite imaging, Penn State researchers for the first time identified a major magma supply into a reservoir extending almost two miles from the...

Research shows humans thrived through Toba super-volcanic eruption

Imagine a year in Africa that summer never arrives. The sky takes on a gray hue during the day and glows red at night....

The secrets of garnet reveal source of water to fuel powerful...

Among geologists who study powerful earthquakes and volcanoes, there is a mystery: as one of Earth's tectonic plates slides beneath another in a subduction...

Scientists capture sounds of volcanic thunder

Researchers report in a new study that they've documented rumblings of volcanic thunder for the first time, a feat considered nearly impossible by many...

Scientists find seismic imaging is blind to water

When an earthquake strikes, nearby seismometers pick up its vibrations in the form of seismic waves. In addition to revealing the epicenter of a...

Scientists helping to improve understanding of plate tectonics

Scientists at The Australian National University (ANU) are helping to improve understanding of how rocks in Earth's hot, deep interior enable the motions of...

Underwater volcano behavior captured by timely scientific expedition

Researchers got a rare opportunity to study an underwater volcano in the Caribbean when it erupted while they were surveying the area. The research, published...

Ash from dinosaur-era volcanoes linked with shale oil, gas

Nutrient-rich ash from an enormous flare-up of volcanic eruptions toward the end of the dinosaurs' reign kicked off a chain of events that led...

Another clue for fast motion of the Hawaiian hotspot

The island chain of Hawaii consists of several volcanoes, which are fed by a "hotspot." In geosciences a "hotspot" refers to a phenomenon of...

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...
