Geological exploration reveals Australian super volcano
A geological survey team says an ancient super volcano exuded more than 450 cubic kilometres of molten magma in a single eruption, over what are now Ngaanyatjarra tribal lands.
Study shows volcanic eruptions beneath bodies of water can cause widespread dispersal of diatoms
Harmful particles in Icelandic volcanic ash fell first, says new research
The type of particles which are most harmful to jet engines were the first to fall out of the Eyjafjallajökull ash plume following the volcano's eruption in 2010, delegates at the Goldschmidt conference will be told today.
New Zealand volcano lets off steam
A volcano off New Zealand sent a plume of steam two kilometres (1.24 miles) into the air Tuesday, although volcanologists described the eruption as small and said it was over in minutes.
Some volcanoes 'scream' at ever-higher pitches until they blow their tops
It is not unusual for swarms of small earthquakes to precede a volcanic eruption. They can reach a point of such rapid succession that they create a signal called harmonic tremor that resembles sound made ...
Melting in the Afar helps scientists understand how oceans form
Lavas from the Afar Depression in Ethiopia, where three tectonic plates are spreading apart, have given scientists a new insight into how ocean basins form.
Searching for objects in turbulent seas
Imagine an object was dropped in the stormy sea. It may be a life raft, a person overboard or a black box from an aircraft. One needs to find it, or at least predict where to search for it.
Pacaya volcano erupts in Guatemala
Guatamala's Pacaya volcano erupted early Thursday, sending volcanic material more than 400 meters in the air, authorities said.
Chile, Argentina on red alert over Copahue volcano (Update)
Chilean and Argentine officials issued a red alert Monday for the increasingly active Copahue volcano bordering the two countries and ordered the evacuation of about 3,000 people.
Mexican volcano rumbles, but residents shrug it off
Mexico's Popocatepetl volcano has blown steam for days, prompting authorities to prepare for possible evacuations, but residents are used to their towering neighbor's rumblings and keep going to work without ...
No Redoubt: Volcanic eruption forecasting improved
Forecasting volcanic eruptions with success is heavily dependent on recognizing well-established patterns of pre-eruption unrest in the monitoring data. But in order to develop better monitoring procedures, ...
Research finds second source of potentially disruptive Icelandic volcanoes
New research by The Open University and Lancaster University discovered another type of Icelandic volcanic eruption that could cause disruption. Published in Geology (February 2013), the team found magma ...
New research improves estimates of amount of ash in volcanic clouds
(Phys.org)—The amount of ash released by Iceland's Eyjafjallajökull volcano during April 2010 was significantly underestimated at the time of the eruption, according to a new model developed at the University ...
Eruption risk perception disconnected from detected threat
The perceived risk of having a volcanic eruption needs to match the actual risk, detected through combined technologies including remote sensing of volcanic gasses, before dire consequences can be prevented.
