Deep faults and disrupted crater at Acheron Fossae
These images were taken by the High Resolution Stereo Camera (HRSC) on board ESA's Mars Express of the Acheron Fossae region, an area of intensive tectonic (continental 'plate') activity in the past. The images show traces of enormous stress and corresponding strain in the crust of the Red Planet. The HRSC was pointed twice at this interesting... view more... (2004-05-07)
'Rosetta Stone' of supervolcanoes discovered in Italian Alps
Scientists have found the "Rosetta Stone" of supervolcanoes, those giant pockmarks in the Earth's surface produced by rare and massive explosive eruptions that rank among nature's most violent events. The eruptions produce devastation on a regional scale - and possibly trigger climatic and environmental effects at a global scale. view more (2009-09-21)
65-million-year-old asteroid impact triggered a global hail of carbon beads
The asteroid presumed to have wiped out the dinosaurs struck the Earth with such force that carbon deep in the Earth's crust liquefied, rocketed skyward, and formed tiny airborne beads that blanketed the planet. view more (2008-05-06)
Ancient mineral shows early Earth climate tough on continents
A new analysis of ancient minerals called zircons suggests that a harsh climate may have scoured and possibly even destroyed the surface of the Earth's earliest continents. view more (2008-06-16)
Unusual mechanism of the Ambrym and Pentecost Islands earthquake in Vanuatu
The Vanuatu island arc, in the South-West Pacific, is 1 700 km long. It corresponds to a convergence zone where the Australian plate is slipping eastwards under the North Fiji Basin, which is part of the Pacific plate, thus generating earthquakes. On 26 November 1999, the central islands of Vanuatu, particularly Ambrym and Pentecost, were strongly... view more... (2004-02-20)
Satellite methods for monitoring volcanic activity in the Andes Cordillera
The central part of the Andes situated between southern Peru and Chile bears 50 active or potentially volcanoes, spread along a 1500 km-long arc. These volcanic structures mostly rise to between 4000 and 7000 m, are very remote with abrupt slopes and are often cloaked in snow. view more (2007-10-08)
Physicist: Stars can be strange
According to the "Strange Matter Hypothesis," which gained popularity in the paranormal 1980's, nuclear matter, too, can be strange. view more (2006-12-19)
An active spreading ridge discovered off the Futuna Islands (South-West Pacific)
In the context of a French national research programme on natural hazards, a bathymetric survey was undertaken off the Futuna and Alofi Islands in the South-West Pacific. Its objective was to improve knowledge of deformations of the oceanic lithosphere in this part of the Pacific which suffers intense seismic activity. During the campaign, called... view more...

Ancient rocks show how young Earth avoided becoming giant snowball
A greenhouse gas that has become the bane of modern society may have saved Earth from completely freezing over early in the planet's history, according to the first detailed laboratory analysis of the world's oldest sedimentary rocks. view more (2007-02-06)
Scientists launch deep-sea scientific drilling program to study volatile earthquake zone
Today, the Nankai Trough Seismogenic Zone Experiment (NanTroSEIZE) gets underway, with the Japanese drilling vessel Chikyu departing from Shingu Port with scientists aboard, all ready to log, drill, sample, and install monitoring instrumentation in one of the most active earthquake zones on Earth. view more (2007-09-21)
Chinese earthquake provides lessons for future
The May 12 Sichuan earthquake in China was unexpectedly large. Analysis of the area, however, now shows that topographic characteristics of the highly mountainous area identified the mountain range as active and could have pointed to the earthquake hazard. Topographic analysis can help evaluate other, similar fault areas for seismic risk,... view more... (2008-07-22)
Mega Eruption of Yellowstone's Southern Twin
North America isn't the only continent that's experienced super-colossal volcanic eruptions in the recent geologic past. view more (2006-03-29)
Mars -- Red Planet once blue planet
A team of Canadian and U.S. researchers have uncovered evidence that ragged, kilometre-high undulating features on the surface of Mars were shorelines of massive ancient oceans that once covered one-third of the planet in water. view more (2007-06-14)
China quake rare and unexpected, says new MIT study
A new analysis of the setting for last month's devastating earthquake in China by a team of geoscientists at MIT shows that the quake resulted from faults with little seismic activity, and that similar events in that area occur only once in every 2,000 to 10,000 years, on average. view more (2008-07-01)
Increased flow of groundwater after earthquakes suggests oil extraction applications
The most obvious manifestation of an earthquake is the shaking from seismic waves that knocks down buildings and rattles people. Now researchers have established a more subtle effect of this shaking—it increases the permeability of rock to groundwater and other fluids. view more (2006-06-29)
Earthquakes Happen at Full Moon
Russian physicists have found that flashes of neutron radiation from the Earth surface are bound to increasing in seismic activity. They believe that this phenomenon can be used as a novel kind of earthquake foreboding. The researchers of the Department of Cosmic Radiation of the Research Institute of Nuclear Physics at Moscow State University... view more... (2001-02-02)
New data shakes accepted models of collisions of the Earth's crust
New research findings may help refine the accepted models used by earth scientists over the past 30 years to describe the ways in which continents clash to form the Earth's landscape. view more (2007-02-08)
Asteroid attack 3.9 billion years ago may have enhanced early life on Earth, says CU-Boulder study
The bombardment of Earth nearly 4 billion years ago by asteroids as large as Kansas would not have had the firepower to extinguish potential early life on the planet and may even have given it a boost, says a new University of Colorado at Boulder study. view more (2009-05-21)
Mountain ranges rise dramatically faster than expected
Two new studies by a University of Rochester researcher show that mountain ranges rise to their height in as little as two million years-several times faster than geologists have always thought. view more (2006-01-27)
Eddies Warm Up The Ocean
Eddies appear in the ocean like in the atmosphere. Atmospheric eddies are short-lived, extremely speedy, and often very hazardous. Oceanic eddies are slower and can be observed only with the use of special equipment, but these eddies gently mixing ocean waters affect the climate in general. For more than ten years specialists from the Pacific... view more... (2002-02-19)
