There must be few things more frightening than being caught up in the deadly path of an all-absorbing lava flow. Imagine the intense heat, being spattered with skin-scalding magma that’s erupting from the depths beneath or being covered in blistering hot ash spewed forth from the gaping mouth of the giant fiery furnace.

We’ve unearthed some fascinating images of the devastation and destruction caused by the devouring nature of eruptive volcanoes. We hope you’ll agree they make for compulsive viewing.

Scientists at the National Oceanography Centre, Southampton, are set to explore the world's deepest undersea volcanoes and find out what lives in a 'lost world' five kilometres beneath the Caribbean.

The team of researchers led by Dr Jon Copley has been awarded £462,000 by the Natural Environment Research Council to explore the Cayman Trough, which lies between Jamaica and the Cayman Islands. This rift in the Caribbean seafloor plunges to a depth of more than 5000 metres below sea level. It contains the world's deepest chain of undersea volcanoes, which have yet to be explored.

"The deep ocean is the largest ecosystem on our planet, so we need to understand its patterns of life," says Dr Copley. "Deep-sea exploration has also given us new cancer treatments and better fibre-optic cables for the internet, both thanks to deep-sea creatures."

"The Cayman Trough may be a 'lost world' that will give us the missing piece in a global puzzle of deep-sea life,"

Few things in nature are as unpredictable as the majestic volcano. Unleashing billowing ash, lava and pyroclastic flows when the Earth’s tectonics plates push and shove at each other like bullies in a playground, volcanoes are testament to the devastating and deadly forces of nature. Their power and might have seen them worshipped in the past, feared always and trusted, never, yet we still are drawn by their beauty, even in the face of destruction.

We’ve unearthed some of NASA’s best satellite images of volcanoes from around the world, revealing the other side of these fiery demons. Their allure remains uncanny but not unsurprising.

Spectacular Chile Volcano Eruption

Nature still has the best special effects....

Chile Volcano eruption!!
Several weeks ago, a volcano that had been dormant for 9,000 years near the
coast of Chile erupted spectacularly, hurling liquefied rocks many miles
into the sky with lightning. The results, which you see here, are called a

'dirty thunderstorm,' and are quite rare.

Nobody is certain what causes them, but according to National Geographic
it's believed to be 'the result of rock fragments, ash, and ice particles in
the plume colliding to produce static charges-just as ice particles collide
to create charges in regular thunderstorms.'

The Mars Webcam

clipper's remarks: The VMC is operated by the Mars Express Flight Control Team, based at ESOC, Darmstadt, Germany. This activity is conducted on a 'best-effort, last-priority' basis given the availability of planning time, command upload time and data down-link capacity.

This is a unique situation, as Flight Control Teams for ESA missions usually do not 'operate' payload instruments; this is done by dedicated, specialised science teams. But the VMC is different: it had a purely operational purpose (successfully completed in 2003 with Beagle's separation) and as such it is not operated by scientists, but by flight controllers.

Recent Volcanic Activity

Several volcanoes have erupted in the past few months - two in Chile (Chaiten and Llaima) and one in Alaska (Okmok). At any given time, approximately 20 to 50 volcanoes are active worldwide (depending on the definition of "active"). Collected here are photos of volcanic events from the the past several years, seen from many angles, including low Earth Orbit. (15 photos total)

You can use a webcam to sneak peeks at birds’ nests, active volcanoes, watch the Shuttle launch, and even to check traffic. But that’s just local stuff. What if you want more of a far look?

Then you need to check out the most distant webcam (so far) in the solar system: the Mars Express Visual Monitoring Camera

This camera on board Europe’s Mars Express orbiter has been circling the red planet since 2003. It was used to confirm the Beagle lander’s separation from the main spacecraft, and that completed its main mission. But last year, controllers wondered if the camera could be turned back on to provide some tourist views of Mars, so they began a new campaign to check out the camera. It turned on just fine

The image above shows something we never can see from Earth: a crescent Mars, with the Sun peeking over the limb (you need to have Mars between you and the Sun to see this, and Earth is always closer to the Sun than Mars)

People do all kinds of crazy things in Hawaii, but flying balloons over a volcano usually isn't one of them. Unless you're Adam Durant, that is.

Durant, an adjunct geological sciences faculty member at Michigan Technological University, and colleagues took meteorological balloons to the Kilauea volcano this summer to make the first on-location measurements of volcanic gases as they actually spew from the mouth of the volcano. The Kilauea volcano began erupting in March.

The first flight was a success and made the first in situ measurements of gases in a volcanic plume using meteorological balloons," Durant reported in a talk at Michigan Tech.

In addition to seeing volcanoes up closeDurant and his colleagues wear goggles and breathing masks at the infernal mouth of the volcanohe analyzes the plumes using controlled meteorological (CMET) balloons, which have altitude control and drift with winds.

Ice Volcanoes of Titan May Habor Life

Fri, 15 Aug 2008 21:15:21 GMT

clipper's remarks: For almost thirty years, scientists have known that complex carbon compounds called tholins exist on comets and in the atmospheres of the outer planets. Theoretically, tholins might interact with water in a process called hydrolysis to produce complex molecules similar to those found on the early Earth.

Could tholins formed in Titan's atmosphere react with liquid water temporarily exposed by meteor impacts or ice volcanoes to produce potentially prebiotic complex organic molecules — before the water freezes?

Laboratory research by Catherine Neish, a graduate student working on her doctorate in planetary science at the University of Arizona, suggests, not without controversy, however, that, over a period of days, compounds similar to tholins can be react with water at near-freezing temperatures.

Titan, the sixth and largest moon of the planet Saturn, is thought to be made largely of ice. Some of that ice may melt during meteor impacts or in underground processes, producing "ice volcanoes" that emit a "lava" containing ammonia mixed with water.

New observations of Titan by the Cassini spacecraft suggest the presence of cryovolcanism on the moon's surface. Cryovolcanism has important astrobiological implications, as it provides a means of exposing Titan's organics to liquid water, transforming hydrocarbons and nitriles into more evolved and oxidized prebiotic species.

Ganesa Macula, a mountain on Titan, is believed to be an '"ice volcano" that periodically belches "lava" containing liquid water. Simulated lab research by University of Arizona graduate student Catherine Neish suggests this water may react with organic compounds in Titan's atmosphere to create complex molecules similar to those on the early Earth.

Strange Rites

Cannibalism: I'd Like My God Medium Rare, Please. With a Nice Chianti.

Even suggesting a connection between cannibalism and Christian mass may sound extreme to believers, but just as the crucifixion of Jesus has a lot in common with older religious practices of human sacrifice, so too does the idea of transubstantiation — wine and bread becoming the blood and body of Jesus — have a lot in common with older religious practices of cannibalism. Crucifixion and mass are easier to understand if one understands the religious background of human sacrifice and cannibalism.

The concept of sacrificing something important to the gods or spirits was common in religions around the world.

For the Aztecs, consuming human flesh was a type of communion, establishing a sacred relationship between humans and gods. Because the people who were ritually sacrificed were "impersonators" of the gods, the Aztecs saw themselves as not consuming another human being, but as consuming a god.

San Andreas Fault Longer Than Thought

(July 30) - As if the San Andreas Fault weren't long and menacing enough, newly found mud pots and mud volcanoes now suggest it extends another 18 miles, going under the Salton Sea and beyond, in the desert southeast of Palm Springs.

California's Earthquake Source

Cassandra Shie, AOL

The San Andreas Fault line, which runs roughly 700 miles through California's west coast, is longer than previously thought, researchers found. The line, which separates different plates of land that move in different directions and cause earthquakes, extends another 18 miles in the desert southeast of Palm Springs.

Ancient Sunken Islands Found

An image from the ROV Tiburon shows deep-sea beach sand and lava that appears to have been sculpted by waves — along a shore now nearly a half-mile (680 meters) below the surface.

Sandy beaches are plentiful along the California coast, but not many are found below the ocean. Scientists just added three to the list.

What were once volcanic islands off the coast of California now sit at the bottom of sea.

With the help of a robotic submersible, a team of researchers captured images of long-sunken sandy beaches at depths exceeding 2,000 feet (610 meters). The video images and rock samples taken from ocean bottom indicate that the beaches were associated with volcanoes that used to poke above the surface.

By Bjorn Carey

"They were probably islands for a million years or less and have been submerged for about the last 10 to 14 million years," Clague told LiveScience, adding that his team hasn’t yet finished dating all of the samples hauled up from below.

"The extension of the San Andreas does not appear to be active. It is probably a very old part of the fault, and helps to explain the larger, more complex transition area between the Imperial fault and San Andreas Fault, called the Brawley Seismic Zone," he said.

U.S. Geological Survey researchers David K. Lynch and Kenneth W. Hudnut report

Using satellite imagery and a physical examination of the land, they identified a cluster of 33 mud pots, mud volcanoes and sink holes which, when plotted, form a clear linear pattern that suggests an underground rift or fault.

Water and gas (CO2 mostly) coming up from below the surface must have a source," Lynch explained. "It is usually associated with an opening in the crust that reaches down to a magma body relatively close to the surface (like Yellowstone). The fact that [the mud pots and mud volcanoes] line up indicates a fault. The fact that they line up with the end of the San Andreas Fault suggests that the two are connected

Seismologists say that enough stress has accumulated at the fault to generate the next "Big One," an earthquake of magnitude 7.0 or greater, any day now or 10 years or more from now.

the region is more complicated than researchers previously thought.
