As the Earth's tectonic plates shift and grind miles below our feet, we feel the effects on the surface in the form of earthquakes and volcanic activity. As Ed Yong of Not Exactly Rocket Science and Chris Rowan of Highly Allochthonous explain, earthquakes far from tectonic plate boundaries may be aftershocks of more violent seismic events along mid-continental faults that occurred hundreds of years...

According to research undertaken by Atalay Ayele of Addis Ababa University in Ethiopia, a 500 metre long, 60 metre deep crack in the Earth’s surface in Afar, Ethiopia, opened in several days. The eruption of the Dabbahu volcano is believed to have widened a rift in the African and Arabian tectonic plates; as volcanic magma spilled [...]

Earthquakes occur within continental tectonic plates as well as at plate boundaries. Do clusters of such mid-plate events constitute zones of continuing hazard, or are they aftershocks of long-past earthquakes?

A landscape photograph by Edward Burynsky can be as frozen as it is arresting. But stare at his portraits of China's Three Gorges Dam or the Alberta tar sands , and you can almost make out Earth in motion. In his massive prints, the built and natural environments slam into each other like tectonic plates, driven by a global economy hurtling forward at full steam. Even if there's little actual oil...

Jerusalem's geology has been crucial in molding it into one of the most religiously important cities on the planet, according to a new study.It started in the year 1000 BCE, when the Jebusite city's water system proved to be its undoing.

FROM- American Thinker By James R. Fencil Earth operates a network of molten upwellings from deep seams in the planet's crust which act to shove tectonic plates across the seafloors where these plates bump into continental land outcroppings. There the spreading plates subduct beneath the continental rims and simultaneously thrust mountains upward from sea level. Such crustal movements continue to alter...

The steady stream of water main breaks may be about not only our infrastructure collapsing , but also shifting tectonic plates, reports the Los Angeles Times . The Jet Propulsion Laboratory is looking into whether a rash of minor earthquakes may be causing the mains to bust open. Andrea Donnellan, a geophysicist at JPL, confirmed there's been a change in normal ground movement as of late, but added...

An international team of scientists says it has created the most complete seismic image of the Earth's crust and upper mantle located under the Himalayas. The scientists said their research identified some unusual geologic features that might explain how the world's largest mountain range formed. Oregon State University Associate Professor John Nabelek, lead author of the study, said the team discovered...

Using sophisticated seismometers and GPS devices, scientists have been able to track minute movements along two massive tectonic plates colliding 25 miles or so underneath Washington state�s Puget Sound basin. Their early findings suggest that a mega-earthquake could strike closer to the Seattle-Tacoma area, home to some 3.6 million people, than was thought earlier. The deep tremors, which humans...

Ice and glacier coverage at lower altitudes in cold climates more important than collision of tectonic plates, researchers find Scientists have solved the mystery of why the world's highest mountains sit near the equator - colder climates are better at eroding peaks than had previously been realised. Mountains are built by the collisions between continental plates that force land upwards. The fastest...

Most evenings I let the nippers watch The Simpsons at six. I love that program because as we know it plays on different levels, and the youngsters just like the slapstick of it (and they keep quiet when it's on, which is worth, oh I don't know, about a squillion dollars...). After that Neighbours comes on. Now, I don’t follow it because it’s effing awful and the kids usually watch for two...

Rain Water Harvesting in Mumbai, India: Application of GIS Prakash M Apte Abstract: Surface water is inadequate to meet demands of our urban centres. While infiltration of rain water into the sub-soil has decreased, pressure of population growth and industrialization has accelerated the rate of drawing underground water in excess of the rate at which the water table gets recharged by natural means....
