It was only in 2007, when an earthquake off New Zealand's Stewart Island brought an oil seepage to the surface, that international interest in the region as a potential untapped source of crude began to gain momentum. Since that discovery, this g
he magma chamber seen in the new study fed these smaller eruptions and is the source of the park's amazing hydrothermal springs and geysers. It also creates the surface uplift seen in the park, said Bob Smith, a seismologist at the University of Uta
he mountain ranges of the North American Cordillera are made up of dozens of distinct crustal blocks. A new study clarifies their mode of origin and identifies a previously unknown oceanic plate that contributed to their assembly.
sing electromagnetic technology developed and advanced at Scripps, the researchers mapped a large area beneath the seafloor off Central America at the northern East Pacific Rise, a seafloor volcano located on a section of the global mid-ocean ridges
The researchers analyzed pumice and lava from an eruption at Iceland's Torfajokull volcano some 70,000 years ago to search for evidence of the levels of gases from water and carbon dioxide in the eruption. "I was amazed by what I found," La
The scientists discovered the magma layer at the Middle America trench offshore Nicaragua. Using advanced seafloor electromagnetic imaging technology pioneered at Scripps, the scientists imaged a 25-kilometer- (15.5-mile-) thick layer of partially me
The alert level for the aviation industry was raised from "green" to "yellow", which it described as a precautionary measure due to the volcano's "increased earthquake activity." Emergency services said in a separate statement that they had
There's just one catch: the technique relies on a fifth force of nature that has not yet been detected, but some particle physicists think it might exist. The fifth force would be in addition to gravity, the weak and strong nuclear forces and electr
The 11 March 2011 Tohoku-Oki earthquake (Mw9.0) produced the largest slip ever recorded in an earthquake, over 50 meters. Such huge fault movement on the shallow portion of the megathrust boundary came as a surprise to seismologists because this port
"Zircons are heavy minerals, and the uranium and lead elements used to date the ages of these zircons are extraordinarily heavy, so these grains do not easily fly around — they did not blow into Mauritius from a sandstorm in Africa," Hartz told Our
he formation and expansion of bubbles in the magma created a buoyant foam, which rose to the seafloor and then buoyantly detached from the volcano as molten pumice balloons but with chilled margins. During its ascent to the sea surface, the vesicles
A new theory explains why homing pigeons are so good at navigating back to their nests--and why sometimes they are not.
87% of the 15 largest (8.6 magnitude or higher) and half of the 50 largest (8.4 magnitude or higher) earthquakes of the past century are associated with intersection regions between oceanic fracture zones and subduction zones," says Dietmar Muller,
When Rothman's group analysed the genome of Methanosarcina - a methanogen responsible for most of Earth's biogenic methane today - they discovered that the microbe gained this ability about 231 million years ago. The date was close to that of the m
The Himalayan range was formed, and remains currently active, due to the collision of the Indian and Asian continental plates. Scientists have known for some time that India is subducting under Asia, and have recently begun studying the complexity of
Oceanic crust covers two-thirds of the Earth's solid surface, but scientists still don't entirely understand the process by which it is made. Analysis of more than 600 samples of oceanic crust by a team including Carnegie's Frances Jenner reveals
Located about 45 miles south of Baton Rouge, Assumption Parish carries all the charms and curses of southern Louisiana. Networks of bayous, dotted with trees heavy with Spanish moss, connect with the Mississippi River as it slowly ambles toward the G
It is simply ludicrous,” said Karl Karlstrom, 61, a professor of geology at the University of New Mexico who has made more than 50 river trips through the canyon — one with Flowers, when she chipped her samples off the canyon walls — and helped creat
Part painting, part sculpture, Quakescape taps realtime seismological data to create a color-coded visualization of the earth's movements beneath Christchurch, New Zealand.
the first explosion was rooted in a magma chamber about 3 miles (5 kilometers) below the surface, while the three later explosions stemmed from magma chambers at depths of about 7 miles (11.5 km), 12 miles (19 km) and 15 miles (24 km).
Nearly 5 miles across and 3,000 feet deep, the stealth crater has lurked just west of Bow City, Alberta, for millions of years. Since the 1930s, some had suspected a bit of odd-looking, fragmented terrain in the area sat ato
They were also ordered to paymore than nine million euros (almost $12 million) in damages to survivors in the devastated medieval town of L'Aquila in a case that has sparked outrage in the international science community. Seismologists in Italy a
home to the largest active magma body in Earth's continental crust and known for a long history of massive volcanic eruptions.
The quake was caused by at least four undersea fault ruptures southwest of Sumatra, Indonesia, within a 2-minute, 40-second period. It killed at least two people, and eight others died from heart attacks. The quake was felt from India to Australia, i
, climate conditions on Bylot Island will be able to support the kinds of trees we find in the fossilized forest that currently exist there, such as willow, pine and spruce. I've also found evidence of a possible growth of oak a
On one particular day in April 2011, two guides told me they had felt an earthquake while they were on the volcano and that the motion of the ground had actually made them jump. Locals working in restaurants on the main island of Thera became aware o
Photographers CJ Kale and Nick Selway waited more than five years to capture a never-before seen-view of an active volcano. When the conditions were finally right, the two friends risked their lives to get it.
'Trillions of carats' lie below a 35-million-year-old, 62-mile diameter asteroid crater in eastern Siberia known as Popigai Astroblem. The Russians have known about the site since the 1970s.
Shatter cones are surface features with distinctive wavy patterns that are known to be created only by the tremendous force of a meteorite impact or an underground nuclear explosion. What's more, Pratt said his map showed that the feature is circula
A comprehensive analysis of the Cascadia Subduction Zone off the Pacific Northwest coast confirms that the region has had numerous earthquakes over the past 10,000 years, and suggests that the southern Oregon coast may be most vulnerable based on rec
