California's killer quake forced power outages as far away as Canada and Idaho, but no wind turbines in Tehachapi or Palm Springs were damaged, it appears. The quake, measuring 6.6 on the Richter scale, was centred in Northridge, about 70 miles from Tehachapi. "There was no damage," says a Southern California Edison official in Tehachapi. Some turbines were shut off briefly, because of surges in the power system, but there was no structural damage. Curt Maloy, until recently president of the Desert Wind Energy Association, confirms that no turbines were damaged in San Gorgonio Pass, although vibration sensors shut them down momentarily.
