Downtown and West Los Angeles are moving toward the San Gabriel Mountains and the metropolitan area in between will be squeezed slowly over the next several thousand years, according to researchers using precise satellite surveying techniques at NASA's Jet Propulsion Laboratory, Pasadena, CA. The measurements suggest that new mountains may be forming south of the high San Gabriel Mountains. The results come from the Southern California Intergrated Global Positioning System Network, an array of 60 GPS received that continuously measures the constant, tiny movements of earthquake faults throughout Southern California.
