Japan Expands Evacuation Zone

On the one-month anniversary of the devastating earthquake and tsunami, Japan has extended the evacuation zone around Fukushima Daiichi, planning to resettle people from several towns that are between 20 and 30 kilometers from the nuclear plant. The risk is not immediate, according to Japanese officials, but is meant to protect against dangers of long-term exposure to radiation. Overall, 62,000 people will be affected. The move comes as a second large 6.6 aftershock hit northeastern Japan, triggering a brief tsunami alert and shutting down power for two of the damaged reactors.
