(Getty Images) (Newser) – It's been a shaky day all around the globe: A 6.2 earthquake hit off Japan's coast today, and a 6.0 shaker also struck off Cuba's coast. No tsunami warnings have been issued in either location, and no injuries or damage have been reported. In Japan, cooling functions were still intact at the battered Fukushima Dai-ichi nuclear power plant. Meanwhile, in southern California, a 3.5 quake rattled Los Angeles and Orange County this morning, but no damage or injuries have been reported.
