A very rare event happened In the northeastern part of the United States yesterday. A 5.8 magnitude earthquake centered in Mineral, Virginia sent tremors outward, all the way north to New York and New England, and south to North Carolina. Limited damage was reported and some even found the event to be exciting. The earthquake follows a number of natural disasters we have witnessed this year, including Japan's massive quake and tsunami, tornadoes ravaging southern states and the Mississippi River rising to historic levels, flooding cities in its path. And now Hurricane Irene, which experts predict could turn into a category 4 storm, and may hit Florida on Friday. David Biello, associate editor for Scientific American, talks about what seems like a record breaking year for natural disasters.
