Strong earthquakes along the San Andreas fault in southern California are more frequent than previously thought, so the dreaded “Big One” could be just around the corner, US researchers said Friday in a study.

…Strong earthquakes along the San Andreas fault in southern California are more frequent than previously thought, so the dreaded “Big One” could be just around the corner, US researchers said Friday in a study.

University of California at Irvine and Arizona State University scientists examined the geological record stretching back 700 years along the fault line 160 kilometers (100 miles) northwest of Los Angeles.

They found that strong earthquakes — between 6.5 and 7.9 magnitude — shook the area every 45-144 years, instead of the previously established 250-400 years.

Since the last big 7.9 magnitude earthquake struck southern California in 1857, or 153 years ago, scientists believe the next “Big One” could happen at any time.

The scientists on Friday provided an abstract of their study, which will be published in full in the September 1 issue of the magazine Geology.

“What we know is for the last 700 years, earthquakes on the southern San Andreas fault have been much more frequent than everyone…

Saturn’s giant moon Titan has water frozen as hard as granite and Great Lakes-sized bodies of fed by a complete liquid cycle, much like the hydrological cycle on Earth, but made up of methane and ethane rather than on water.

…The significantly lower temperature is a bit of a stumbling block (it’s ten times as far from the sun as us), but there’s a strong possibility of subterranean microbial life - or even a prebiotic “Life could happen!” environment.If a space traveler ever visits Titan, they will find a world where temperatures plunge to minus 274 degrees Fahrenheit, methane rains from the sky and dunes of ice or tar cover the planet’s most arid regions -a cold mirror image of Earth’s tropical climate, according to scientists at the University of Chicago.Titan’s ice is stronger than most bedrock found on earth, yet it is more brittle, causing it to erode more easily, according to new research by San Francisco State University Assistant Professor Leonard Sklar. Sklar and his team developed new measurements from tests on ice as cold as minus 170 degrees Celcius which demonstrate that ice gets stronger as temperature decreases. Understanding ice and its resistance to erosion is critical to answering how Titan’s earth-like…
