According to Japan’s Meteorological Agency, a 6.0 magnitude earthquake hit eastern Japan on Wednesday and buildings shook in the capital Tokyo.
No tsunami warning was immediately issued, but the agency warned of a possible change in sea levels.
The tremor report comes five days after a massive tremor sparked a devastating tsunami in the country’s northeast coast.
Following Japan’s Friday devastating quake and tsunami, all attention has been directed to the Fukushima nuclear plant, where several explosions have caused the release of radioactivity into the atmosphere.
Nuclear radiation exposure can cause serious health problems. The first signs of nuclear radiation exposure are nausea and vomiting.
It can increase the probability of developing some other diseases, mainly cancer, tumors, and genetic disorders.
The Japanese National Police Agency said on Tuesday that nearly 3,373 people were confirmed dead, but the death toll is expected to dramatically rise and eventually exceed 10,000.
