Understanding Europe's topography
Europe's shape is in a constant change: The Mediterranean basin is shrinking, the Alps are rising and pushing North, and Scandinavia is still rebounding after having been crushed by the weight of a thick and huge ice sheet in the ice ages. But what did Europe look like in the past, what are the... view more (2008-11-24)
Mercury's shifting, rolling past
Patterns of scalloped-edged cliffs or lobate scarps on Mercury's surface are thrust faults that are consistent with the planet shrinking and cooling with time. However, compression occurred in the planet's early history and Mariner 10 images revealed decades ago that lobate scarps are among the... view more (2008-03-18)
Newly discovered active fault building new Dalmatian Islands off Croatian coast
A newly identified fault that runs under the Adriatic Sea is actively building more of the famously beautiful Dalmatian Islands and Dinaride Mountains of Croatia, according to a new research report. view more (2008-01-23)
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)
Why a Rocky Mountain high?
A University of Utah study shows how various regions of North America are kept afloat by heat within Earth's rocky crust, and how much of the continent would sink beneath sea level if not for heat that makes rock buoyant. view more (2007-06-25)
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)
Scientists use seismic waves to locate missing rock under Tibet
Geologists at the University of Illinois at Urbana-Champaign have located a huge chunk of Earth's lithosphere that went missing 15 million years ago. By finding the massive block of errant rock beneath Tibet, the researchers are helping solve a long-standing mystery, and clarifying how continents... view more (2007-02-08)
Seismologists detect a sunken slab of ocean floor deep in the Earth
Halfway to the center of the Earth, at the boundary between the core and the mantle, lies a massive folded slab of rock that once formed the ocean floor and sank beneath North America some 50 million years ago. view more (2006-05-18)
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)

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... view more (2004-05-07)
Journal of Geological Society salutes Young Author 2003
The Geological Society of London's flagship journal has chosen Ingrid Ukstins Peate to be Journal of the Geological Society Young Author of the Year 2003. The award was given for the paper The transition from sedimentation to flood volcanism in the Kangerlussuaq Basin, East Greenland, published in... view more (2004-03-10)
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... view more (2004-02-20)

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... view more (2000-05-22)
