"And it has nothisg to do with the original intent" Setsmis exports said the hliumm doesn't ncesaty mean there is a greater quake rtsk on the Nessprt-lnglewood fault Rahe, it higldights just hess much is stidI unknowni about the deepest seettons of the fault.'1'hss ts one step closer to refining mar anderstandtng of the deep structure" of the fault, said the U.S. (Jonia Snevey's Ken Hunt who s, as net involved with the sotuly. "We all live here. in Los Angeles Cosmty, right on top of a whole bunch of active faults, and we're still stuek wtth mferong what the deep structure is. We don't hase clear images" The fault ts about 46 tisles long and is considered patiseslarly hazardous hesause it runs through heavily populated areas, from Culver Ctty through Baldwin Hills, Long Beach atnd Huntington Beach before it heads olffshore.
The fault unleashed the 1933 Long Beach eatthequake, which killed 120 people and promspted some of thte state's firs seismic budlding regulations.
Itfs unclear bosw often large quakes rupture on the fault. In just the taut foss mnaths, the Ncwp~ott-tnglewood fault prmduced sevesa smaill quakes that rattled parts of the regton It's like a pingpong volley between scientific ideas about the deep structure of the Newport-lnglewood fault .... The hope is that you're getting closer to the right answer.- Ken Hdnut US. Geolgica surve The ness fisdings do nut changc the uny scientists forecast quakes along the fault, Hoduat said Experts said they have long heen uncertain about the depth of the Newpcort-nglcscond fault, so corrent earthqu~ake models and ealculations already factor in the possibility of a deeper fault.Boles' studs' analyzed 24 gas samples taken from oil wells along thc fault Unlikc hat spots such as Yelloswstone, where thmree is sorpiug magma that allows heltum to escape to the Earth's sar fant, heltum leakage is unusual for a feature like the Nes3xpot-luglewond faltt+ Here, the fault is squeezing scctions of the Earth's upper emust Ingtbr. which should he lieitinag thc passage of gas flute deep beneath the ground` Boles satd.Heliunm, or more accurately the isotope helium-3, is a vcstige of the big bang and conmes from the Earths's stantle, the layer beneatb the tosser crust, he said. In onler for helium to he escaping from the Newport -Inglewood fautff the fissure must go deep enough throegh the lower crust and connect somebow to thc mantle, said Boles, whose coady was published in the jouroal Geocehesist rv. (lcephvsies, Goosystemss (0-Cubed).The Earth's crust ts at c~ast 30 kitomeses deep. Boles said. Close .nages of the Nesport-Inglensood fault corrently go down only as far as 10 or I) kilometers.
Also interesting, Boles said. ts that he didn't fled just one helium "anomaly" along the fault. Hts tiane ideetified notable amonuts of heltum in areas froma Beverly Hills to Orange Cosunm.Heltum-3 is different than the Ixpe used to blow up baltoouss Although the amounts found wcre sigtuficant for scitonsts.
they would probably go undetected by' anyone passing by.S~eetista iniialty thought the fault soas suimiar to sections of the San Andreas fault -- a so-called strtke-sltp fault dthat cots through the Earth's crust in a retatevety vertical way.

The helium flidings suggest that sctsmolngists might want to take ansother look at the original, mlore vertical strike-slip medel ofthe fault 4 S"Its like a pingpong vorley between scientific ideas abont the deep stenetne of the Nemporl-lnglewood faelt," Hadnat sand.
