Elevated levels of radioactive elements found at Louisiana sinkhole site

Louisiana massive sinkhole gets bigger every day and gas bubbles have been located now in thirteen sites on the bayous around Ground Bayou. After a section of pipeline in the slurry area became bent, officials asked natural gas companies operating near the sinkhole to

Louisiana sinkhole - fears of radioactivity and gas explosion as sinkhole gets bigger

Boiling bubbles in the waters of Bayou Corne, in Assumption Parish, about 50 miles south of Baton Rouge in Louisiana, US, concerned residents in mid-May. Then, suddenly a massive sinkhole appeared on August 3. It forced the closure of nearby highway 70 after a gas

New mountain found on the ocean floor off the coast of Iceland

Multi-beam measurements on a mission of research vessel Arni Fridriksson earlier this summer revealed vast underwater mountain deep roots from the continental shelf of 120 nautical miles west of the peninsula. The unnamed mountain on the ocean floor off the west coast

Plate tectonics discovered on Mars

A UCLA scientist has discovered that the geological phenomenon known as "plate tectonics", which involves the movement of huge crustal plates beneath a planet's surface, also exists on Mars. An Yin, planetary geologist and a UCLA professor of Earth and space sciences

New study shows Cascadia Subduction Zone earthquake risk to be much higher than previously thought

America's Pacific Northwest has a 37% chance of being hit by a magnitude 8 or larger earthquake in the next 50 years, a new study shows. That's more than double previous estimates of a 10-15% risk. Great Subduction Zone earthquakes are the largest

Growth of Earth's inner core may be a precursor to the magnetic reversal

A new finding suggests that shifts in the geomagnetic field are connected to growth of the inner core. Peter Olson and Renaud Deguen of Johns Hopkins University in Baltimore, Maryland, used numerical modelling to establish that the axis of Earth's magnetic field

Can fracking contaminate drinking water?

Hydraulic fracturing uses pressurised fluid to crack open deep shale rocks to release the methane trapped within them. Geologists say this potentially harmful fluid is unlikely to percolate up through a few kilometres of rock to reach the shallow aquifers that supply

Residents of Assumption Parish (US) report earth tremors and venting streams of natural gas surfacing the waterways

Residents in a swampy area of northern Assumption Parish reported earth tremors as well as venting streams of natural gas roiling the surface of waterways for about a month. Residents reported tremors last month and again on Tuesday and Wednesday. Assumption Parish

Understanding earthquakes and tectonic tremors

Seismic stations worldwide are recording strong earthquakes on daily basis. Every month the earth is shaken by approximately 80,000 earthquakes, at a rate of 2 earthquakes a minute. There is an earthquake taking place somewhere right now.Within the last few years

Seattle fault can generate bigger earthquakes then previously thought

The Seattle Fault, a zone of east-west thrust faults under the Puget Sound and Seattle, last ruptured in a magnitude-7.0 to -7.5 earthquake about 1,100 years ago. It's due for another one, but scientists don't know when that might happen. However, they warn that an

Almost vanished Poplar Island is slowly reappearing

The crust under the Chesapeake Bay is sinking, while sea levels are rising. Made of clay and silt, the islands erode quickly, and many have disappeared altogether. Small islands were once a nesting  habitat for water birds and turtles, while the larger islands

Creeping quakes show that New Zealand's earthquake-prone landscape is even more unstable than previously thought

Researchers recorded New Zealand's deep tremors lasting up to 30 minutes on its biggest fault line - the Alpine Fault, which runs the length of the South Island. The quakes, which caused no surface damage, occurred 20-45 kilometres (12-28 miles) beneath the Earth's
