UF study: Isthmus of Panama formed as result of plate tectonics
Contrary to previous evidence, a new University of Florida study shows the Isthmus of Panama was most likely formed by a Central American Peninsula colliding slowly with the South American continent through tectonic plate movement over millions of years.   view more (2008-07-30)

Stress Buildup Precedes Large Sumatra Quakes
The island of Sumatra, Indonesia, has shaken many times with powerful earthquakes since the one that wrought the infamous 2004 Indian Ocean tsunami. Now, scientists from the California Institute of Technology and the Indonesian Institute of Sciences are harnessing information from these and earlier... view more (2008-05-28)

Deep-ocean drilling researchers target earthquake and tsunami zone
Researchers fresh from an eight-week scientific drilling expedition off the Pacific coast of Japan today reported their discovery of strong variation in the tectonic stresses in a region notorious for generating devastating earthquakes and tsunamis, the Nankai Trough.   view more (2007-12-13)

Scientists aim to unlock deep-sea 'secrets' of Earth's crust
Scientists from Durham University will use robots to explore the depths of the Atlantic Ocean to study the growth of underwater volcanoes that build the Earth's crust.   view more (2008-05-14)

Silent earthquakes may foreshadow destructive temblors, study finds
A team of American geoscientists is urging colleagues around the world to search for evidence of tiny earthquakes in seismically active areas, such as the Pacific Northwest, that are periodically rocked by powerful temblors of magnitude 8 and higher.   view more (2006-07-06)

Investigating the deepest layers of the Earth's crust
The deep layers of the Earth's crust and the upper part of its mantle have been the target for investigation by a number of research groups at the EHU/UPV. This deep zone, and the processes that have taken place there in the past, can be investigated by means of studying those rocks which today are... view more (2004-02-04)

'Ultrasound' of Earth's crust reveals inner workings of a tsunami factory
Research announced this week by a team of U.S. and Japanese geoscientists may help explain why part of the seafloor near the southwest coast of Japan is particularly good at generating devastating tsunamis, such as the 1944 Tonankai event, which killed at least 1,200 people. The findings will help... view more (2007-11-16)

Complex structure observed in Tonga mantle wedge has implications for the evolution of volcanic arcs
The subduction zones where oceanic plates sink beneath the continents produce volcanic arcs such as those that make up the "rim of fire" around the Pacific Ocean.   view more (2007-04-13)

Seismologists see Earth's interior as interplay between temperature, pressure and chemistry
Seismologists in recent years have recast their understanding of the inner workings of Earth from a relatively benign homogeneous environment to one that is highly dynamic and chemically diverse.   view more (2007-10-26)

Carbon dioxide and climate - the plot thickens
Using a novel technique, the researchers obtained a best estimate for carbon dioxide levels 43 million years ago of 385 parts per million (ppm), slightly higher than today's figure of 360 ppm. This result is far below earlier estimates which suggested that carbon dioxide levels were up to six times... view more (1999-06-08)

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)

Amadeus and Esmeraldas: two marine geophysics campaigns to investigate strong earthquakes off Ecuador and Colombia
Several large earthquakes with magnitude higher than 8 on the Richter scale have already occurred along the margins between the Nazca and South American tectonic plates, under the ocean off Ecuador and Colombia. This region is vulnerable, all the more so because since the 1980s, Ecuador's oil... view more (2005-02-16)

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)

Journey to the center of the earth: Discovery sheds light on mantle formation
Uncovering a rare, two-billion-year-old window into the Earth's mantle, a University of Houston professor and his team have found our planet's geological history is more complex than previously thought.   view more (2008-04-11)

Study of 2004 tsunami forces rethinking of giant earthquake theory
The Sumatra-Andaman earthquake of Dec. 26, 2004, was one of the worst natural disasters in history, largely because of the devastating tsunami that followed.   view more (2006-03-06)

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)

Scientists explain source of mysterious tremors emanating from fault zones
Tiny tremors and temblors recently discovered in fault zones from California to Japan are generated by slow-moving earthquakes that may foreshadow catastrophic seismic events, according to scientists at Stanford University and the University of Tokyo.   view more (2007-03-15)

Mineral ages show Blue Mountain rocks related to Klamath, Sierra Nevadas
New evidence, based on mineral dating, suggests that rocks of the Blue Mountains, the oldest geological formation in Oregon, may have been derived from the Klamath and Sierra Nevada mountain chains, University of Oregon researchers report.   view more (2007-10-30)

Eastern California shear zone puzzles seismologists
Residents and seismologists in Northern California focus on the San Andreas Fault, but a Penn State researcher thinks more questions should be asked about the Eastern California Shear Zone, a fault that ends or dissipates without a clear connection.   view more (2005-10-18)

Lighting the Way: Measuring Surface Tension Just Got Easier
Inventors at Oxford University have developed a new method to indirectly measure the surface tension of liquid by tracking reflected light intensity to assess the surface configuration. The procedure is reliable, repeatable, quick to set-up and use, contact-less and non-destructive. Surface tension... view more (2003-09-05)

Hotspots or Not? Isotopes Score One for Traditional Theory
One great beauty of plate tectonics theory is that it explains so many geological phenomena at one time. But plate tectonics could not explain the location of many volcanic islands - Hawaii, the Azores or the Galapagos Islands, often called "hotspots" - far from the edge of tectonic... view more (2006-12-07)

Building for the Future
Providing motorists with real time information on incidents and road delays, the Highway's Agency state-of-the-art National Traffic Control Centre (NTCC) is taking shape. From 2004, NTCC will play a vital role in the way traffic is managed. Based in the West Midlands, the purpose built centre has... view more (2003-12-01)

Lifeburn - heating systems for domestic application
Heating systems must adjust the thermal power to the needs of the user through the modulation of their thermal power. So a major efficiency, less polluting emissions and more comfort can be obtained. However, the difficulty to develop new radiant burners has slow down the appearing of new... view more (2002-09-23)

UCR physicist demonstrates how light can be used to remotely operate micromachines
A research team led by Umar Mohideen, a physicist at the University of California, Riverside, has demonstrated in the laboratory that the Casimir force - the small attractive force that acts between two close parallel uncharged conducting plates - can be changed using a beam of light, making the... view more (2007-06-01)

Economists Find Just how Much People Value The Status of Personalised Car Number Plates
Status matters a lot to human beings. Economists have long understood this, but have found it almost impossible to research and understand how much we value things that we believe give us status but seem to have little other use. Most economics textbooks simply ignore concerns about status, but now... view more (2002-08-06)
