There has been a massive explosion at the Fukushima Nuclear Power Plant and Russian Television is reporting 4 people have been injured.

Some experts say this is the start of a meltdown.

Russian Television reporters are saying this is very similar to Chernobyl.

CNN reports that 80,000 people living in a 10km radius of the power plant.

Russian reporters are drawing strong comparisons with the world’s worst nuclear disaster, Chernobyl, which happened 25 years ago.  They say the radioactive gas would be invisible.  Reports are now saying some radioactive gases have escaped.

WeatherWatch.co.nz says that winds are currently south-westerly – blowing any radioactive gas north east. 

The map below – provided by weathermap.co.nz – shows a westerly expected.  If this happens it would blow any potential radioactive gas out to sea and away from people.

WeatherWatch.co.nz says the forecast for the next several days shows winds from the westerly quarter, which would mean toxic gases would have a better chance of being blown out to sea and away from land.
