Japan's watchdog Nuclear Regulation Authority announced Wednesday that a radioactive water leak at the crippled Fukushima Daiichi Nuclear power plant was magnitudes more severe than previously thought, further eroding faith in the capacity of the plant owners and government to deal with safety breaches in the aftermath of a disaster there two years ago. 

The NRA increased the severity level of the crisis '" which began when a leak was discovered in a storage tank Monday '" from a level 1 "anomaly' to a level 3 "serious incident' on the International Nuclear and Radiological Event Scale. 

Each number on the scale represents a 10-fold increase in severity, with a level 3 event signaling exposure that exceeds ten times the limit for workers, according to the UN's International Atomic Energy Agency.
