UC Santa Barbara geologist Jim Boles found evidence of helium leakage from the Earth’s mantle along a 30-mile stretch of the Newport-Inglewood Fault Zone in the Los Angeles Basin.

He claims the results show that the Newport-Inglewood fault is deeper than scientists previously thought.

Using samples of casing gas from two dozen oil wells ranging from LA’s Westside to Newport Beach in Orange County, Boles discovered that more than one-third of the sites show evidence of high levels of helium-3 (3He).

‘The results are unexpected for the area, because the LA Basin is different from where most mantle helium anomalies occur,’ said Boles, professor emeritus in UCSB’s Department of Earth Science.

‘The Newport-Inglewood fault appears to sit on a 30-million-year-old subduction zone, so it is surprising that it maintains a significant pathway through the crust.’

Compared to the previous assessment issued in 2008, UCERF2, the estimated rate of earthquakes around magnitude 6.7, the size of the destructive 1994 Northridge earthquake, has gone down by about 30 percent.

The expected frequency of such events statewide has dropped from an average of one per 4.8 years to about one per 6.3 years.

However, in the new study, the estimate for the likelihood that California will experience a magnitude 8 or larger earthquake in the next 30 years has increased from about 4.7% for UCERF2 to about 7.0% for UCERF3.

Impressive Vortex Opens on Lake

On June 5, the Tulsa District of the US Army Corps of Engineers opened the gates on the spillway on Lake Texoma, bordering Texas and Oklahoma. The water release created a dramatic-looking vortex in the water.


After two years of searching for a rumored face located on the side of a cliff, a Canadian man has finally hit the jackpot.

Hank Gus, an aboriginal and member of the Tseshaht First Nation, heard about the face from someone who first learned about it after hearing a kayaker describe it in 2008, and decided to set out and look for himself.

It was found on the Reeks Island, part of the Broken Group Islands located in the Pacific Rim National Park Reserve in British Columbia.

Now, the question is whether this is a man-made wonder or just the result of Mother Nature.
