A devastating storm that ripped through Alabama killed at least 128 people, according to the state’s emergency management agency. Many buildings and homes have been destroyed.  Traffic and power have also been disrupted.

A state of emergency has been declare and 1,400 National Guard troops have been dispatched for search and rescue.  The storms happened on Wednesday evening.  

Thirty-two were also killed in Mississippi and eleven in Georgia.  

Just a week ago, another storm hit the South and killed at least 22 in North Carolina.

These natural disasters have knocked out several nuclear reactors in the US.  So far, there are no signs of radiation leaks, but Japan’s experience with its nuclear crisis has raised concerns about the general safety of nuclear power plants when hit by natural disasters.

The year 2011 has been a particularly active time for natural disasters.  The most devastating is Japan’s earthquake and tsunami.  In the US, there have been widespread storms and wildfires.

According to USA Today, April 2011 is the most active month for tornadoes on record, with over 800 reported instances.

Images from Wednesday’s storms are not widely available yet.  Below are two video clips of the storm and images from other recent natural disasters in the US.
