Ice Ages Blamed On Tilted Earth

There's a lot more links I like but I'll do those later...one more article behind the cut.
Btw, I know this fault line
WASHINGTON (Reuters) - A little-known fault that runs under Los Angeles into its suburbs could cause the costliest earthquake in U.S. history and kill as many as 18,000 people if it shifts, geologists said on Wednesday.
The Puente Hills fault has caused quakes of magnitude 7.2 to 7.5 at least four times in the past 11,000 years, said the teams at the U.S. Geological Survey and the Southern California Earthquake Center at the University of Southern California.
This is rare, but building codes and emergency planning should take the risks into account, the quake experts said.
"As an individual, your odds of dying of a heart attack or an auto accident are much greater than of dying from this earthquake," said Ned Field, a USGS researcher who led the study.
"That being said, there are other sources of earthquakes throughout the region, and it's not a question of if, but when, so everyone should take necessary safety precautions."
The Puente Hills fault runs under Los Angeles County and adjacent to Riverside and San Bernardino counties.
A quake of magnitude 7.2 to 7.5 would kill anywhere between 3,000 and 18,000 people, would displace between 142,000 and 735,000 households, and cause up to $250 billion in property damage, the researchers report in the journal Earthquake Spectra.
That would make it the costliest disaster in U.S. history, the researchers said.
The estimates come from 18 different possible quake scenarios, all presuming that the rupture occurs at 2 p.m. on a weekday.
The fault runs under older commercial and industrial structures, they said, while the areas damaged in the 1994 Northridge earthquake, which killed 33 people, were mostly wood-frame residential structures.
"One of the main goals of this study was to use our improved knowledge of seismic hazards in Southern California to evaluate -- and hopefully reduce -- the uncertainties in this type of risk analysis," said Thomas Jordan, director of the Southern California Earthquake Center
