The next great earthquake
The 2004 Sumatra-Andaman earthquake and resulting tsunami are now infamous for the damage they caused, but at the time many scientists believed this area was unlikely to create a quake of such magnitude. view more (2007-03-23)
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 behave when they collide. view more (2007-02-08)
Teachers discover that bacteria prefer milk chocolate
Bacteria prefer milk chocolate to dark chocolate and will swim towards it on an agar plate, so teachers have found out this week (15-19 July) at a summer school run by the Society for General Microbiology at the University of Reading. The experiment is one of a series of A-level practicals currently being produced for teachers by the Society.... view more... (2002-07-17)
Volcano-like tremors detected deep within Earth's crust near San Andreas
Tremors within the Earth are usually-but not always-related to the activity of a volcano. Now, such vibrations have been recorded nowhere near a volcano, but at a geologic observatory at the San Andreas Fault. view more (2006-04-13)
A new twist on power walking
In an unprecedented breakthrough in the development of portable and renewable human-driven energy sources, an MBL (Marine Biological Laboratory) biomechanics expert who studies how muscle moves skeletons in fish and frogs has invented a backpack that gives new meaning to the term power walking. view more (2005-09-09)
A sea change for earthquakes
A reconstruction of land movements and changes in sea levels for three massive historic earthquakes in Alaska gives clues that may help scientists forecast future earthquakes and earthquake-triggered tsunami. To be published in this week's Journal of Quaternary Science¹ the findings should help reduce losses from future catastrophic events. view more (2005-02-21)
Sediment layer may forecast greatest earthquakes
Researchers at Yale and the University of Washington report that great earthquakes, like the 2004 Sumatra earthquake, may be caused by the build up of sediment on top of subduction zones, suggesting a new way to forecast these most severe earthquakes. view more (2006-01-31)
Pacific Northwest tectonic plates are moving
he three major tectonic plates off the Pacific Northwest coast are undergoing a gradual shift, and the area in which they converge - popularly known as the "Triple Junction" - appears to be migrating in a southeasterly direction. view more (2006-04-12)
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)
Sediment could be a major factor in biggest subduction zone earthquakes
The most powerful earthquakes - such as those that shook Indonesia in 2004, Alaska in 1964, Chile in 1960 and the Pacific Northwest in 1700 - occur in subduction zones, areas of the sea floor just offshore where two tectonic plates meet and one dives beneath the other. view more (2006-01-31)
Earth-shattering proof of continents on the move
AFRICA is being torn apart. And as Ethiopia's rift valley grows slowly wider, an international team of scientists is taking a unique opportunity to plot the progress of continents on the move. view more (2007-01-30)
Is a Russian peninsula really part of North America?
For many years geologists have harbored a belief that the Kamchatka Peninsula, shrouded in mystery and secrecy on Russia's east coast, actually sits on the same tectonic plate as the mainland United States, Canada and Mexico. view more (2006-05-03)
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)
Study reconciles long-standing contradiction of deep-earth dynamics
Researchers at Columbia University's Lamont-Doherty Earth Observatory recently resolved a long-standing contradiction about the workings of the deep Earth. view more (2005-08-25)
San Andreas earthquake observatory achieves milestone as drillers penetrate the active fault zone
The San Andreas Fault Observatory at Depth (SAFOD) reached a significant goal on Aug. 2 when scientists drilled into a seismically active section of the fault approximately two miles below the surface of the Earth. view more (2005-08-04)
Bioceramic orbital plate implant
Ceramic materials used for this purpose are known as bioceramics and their fields of application include orthopedic, odontosthomathology, ophthalmology, plastic and cosmetic surgery. view more (2005-10-03)
Geologically produced antineutrinos provide a new window into the Earth's interior
In Jules Verne's nineteenth century classic Journey to the Centre of the Earth, an Edinburgh professor and colleagues follow an explorer's trail down an extinct volcano to the Earth's core. view more (2005-07-28)
Study outlines eruption at undersea volcano
An international team of scientists has presented its findings from the first observations of the eruption of a submarine volcano that in 2004 and 2005 spewed out plumes of sulfur-rich fluid and pulses of volcanic ash 550 meters below the ocean's surface near the Mariana Islands northwest of Guam. view more (2006-05-25)
Plate tectonics may take a break
Plate tectonics, the geologic process responsible for creating the Earth's continents, mountain ranges, and ocean basins, may be an on-again, off-again affair. view more (2008-01-04)
Measure the speed of light using Milky Way Stars®
Nothing travels faster than light - it only takes 8 minutes for it to reach the Earth from the nearest star, the Sun, which is 150 million kilometres away. Now anyone can measure this speed - with chocolate stars and a microwave oven! The experiment is described on a new Institute of Physics web resource for teachers about fun physics... view more...
