An earthquake prediction system installed on some of the world's largest fault lines is unproven and won't be rolled out in New Zealand, government scientists say. US researchers believe they've cracked a way of predicting quakes days before they strike, with the potential to save thousands of lives. The QuakeFinder, developed by a Silicon Valley firm, uses a series of sensors to measure changes in underground static electricity. As a shake starts building, the ground releases intense electrical currents "almost like lightening, underground," says QuakeFinder's founder, Tom Bleier. But the system won't be tested here until its science is proven, says GNS. "This theory has been around for quite some time and ... realistically it has a low probability of success," said GNS seismologist Dr Bill Fry. Civilisation has, for centuries, tried various methods of predicting when a deadly quake will strike - by reading bizarre animal behaviour, shiftin...
