A Deep, Dark Mystery [Helium leakage from Earth's mantle in Los Angeles Basin]

Compton, Calif. after the Long Beach Earthquake, which occurred on the fault in question. My aunt lived at the time in Compton, about a half a mile from where the picture was taken. She and her neighbors were afraid to return to their homes for several days for fear of aftershocks.

All geology points to a noachic flood.

Didn't it rain!

Well, if they start there, everything else is likely to be wrong as well. So no wonder their 'theories' don't work out.

There can be large gas leaks before a major earthquake hits....

Thanks Bigg Red.

[snip] ...helium-3 (³He)... is a vestige of the Big Bang. Its only terrestrial source is the mantle. Leakage of ³He suggests that the Newport-Inglewood fault is deeper than scientists previously thought... "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."... high levels of ³He inversely correlate with carbon dioxide (CO₂), which Boles noted acts as a carrier gas for ³He. An analysis showed that the CO₂ was also from the mantle, confirming leakage from deep inside the Earth. [/snip]

Sounds like big trouble. :'o

"If it is correct — then this is very bad news."

What do you think this indicates, if their data is correct?

Newport-Inglewood fault has long been considered a severe threat. It runs under or near the most densely populated areas of LA, including the nationally critical Port of Los Angeles.

Heaven knows old Ben is no scientist, sounds to me that if it extends all the way down to the mantle — then a quake on it will be more devastating than ever thought possible.

[BenLurkin]

Yep.

And though everyone tells me I’m wrong — I think all the recent water main breaks in L.A. are due to the surface being compressed by slowly building pressure under L.A.

Here is another interesting article about a CA fault which may reach to the mantle. I wonder if these places are nearby or the phenomena related? Are these signs of special danger?

I just reread the intro and see that the link I just posted IS related to the same fault area.

How so? We have a daughter in SF ... Thanks in advance.

When you say “SF” do you mean San Fernando or San Francisco?

Because the fault in question poses no threat to San Francisco.
