he team found that the magma chamber was colossal. Reaching depths of between 2km and 15km (1 to 9 miles), the cavern was about 90km (55 miles) long and 30km (20 miles) wide. It pushed further into the north east of the park than other studies had p
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 newly discovered water source could supply half of Africa's driest sub-Saharan country with 400 years of water, reports Matt McGrath of BBC.
What I suspect will work is to produce coarse biochar from sawdust which should be readily available in sufficient amounts to produce the tonnages desired. I would then blend the mill tailings and the biochar on perhaps a ten to one ratio of tailing
have occurred in Iceland four times in roughly the past thousand years, records indicate, the most recent being the deadly and remarkable eruption of Iceland's volcano Laki in 1783-84.
The last tipping point in Earth's history occurred about 12,000 years ago when the planet went from being in the age of glaciers, which previously lasted 100,000 years, to being in its current interglacial state. Once that tipping point was reached,
The current theory of continental drift provides a good model for understanding terrestrial processes through history. However, while plate tectonics is able to successfully shed light on processes up to 3 billion years ago...
Now, Guilherme Gualda of Vanderbilt University and his colleagues present several lines of evidence from the Bishop Tuff deposit at Long Valley, suggesting that the pools are "ephemeral" - lasting as little as 500 years before eruption.
Some of the steepest mountain slopes in the world got that way because of the interplay between terrain uplift associated with plate tectonics and powerful streams cutting into hillsides, leading to erosion in the form of large landslides, new resear
The UK-led team of researchers analysed tiny crystals in rocks erupted from the volcano. These crystals contain a record of events inside the magma chamber such as injections of hot magma or gas. They found that injections of magma or gas into the c
An earthquake in the Indian Ocean off the coast of Sumatra, Indonesia on 11th April was unusually powerful, at magnitude 8.6, for a “strike-slip” type of quake, and a new analysis of the earthquake and its 8.2 magnitude after-shock has proposed that
"the Yellowstone super-volcano is a little less super than previously thought." The bad news: the Yellowstone super-volcano is "more active than previously thought." That means eruptions are more frequent. So the next one is likely closer than pr
This rebound has been countered by some form of major elastic flow from an area close but that was capable of subsiding. The North Atlantic is the only such area available. Thus the argument that parts of the mid ocean ridge subsided cannot be dismis
I'll go with the statement-but it is not the standard statement scientists usually make. The landmass on both maps DOES coincide with a map on the Mid-Atlantic Ridge in the Scientific American a while back, indicating the area of a possible earlier
Early members of an ancient family of trees, the cypresses, grew on the supercontinent Pangaea, and when this giant continent split apart, it shaped the future of these trees, according to research that examined the evolution of these trees, which to
Before the magma separated from the bedrock, the semifluid rock and the leftover solid minerals actively exchanged trace elements. "Different minerals have characteristic ways of separating when trace elements are smelted. In other words, the con
The researchers also found spherules that had collided at high velocities with other spherules during the chaos of impact. Such features, Kennett noted, could not have formed through anthropogenic, volcanic, or other natural terrestrial processes. "
e 250 million years ago when rapid climate change wiped out nearly all marine species and a majority of those on land. Now, they have discovered a new culprit likely involved in the annihilation: an influx of mercury into the eco-system.
Clouds of dust belched from the corners of almost every room in Joe Reneau's house as the biggest earthquake in Oklahoma history rocked the two-story building.
UPDATE 3:15 EDT: It looks like the phreatomagmatic explosive activity is beginning south of El Hierro. Prensa El Hierro tweeted (translated): “Juan Manuel Santana have just announced that produce water columns and ash.” La Restinga is being evacuated
