Sinkholes seem to be occurring more and more everyday. A sinkhole is a natural depression hole in the Earth’s surface cause by sudden and severe shifts in the earth’s surface. Sinkholes can vary in size from 3.3 feet to 2,000 feet both in diameter and depth. However, sinkholes usually only occur in large landscapes shaped by the dissolution of a layer or layers of soluble bedrock. The most recent sink hole occurred in Waterloo, Illinois. On the fourteenth of March, forty three year old Mark Mihal was golfing and got swallowed into a sinkhole. The sinkhole was no bigger than a Hula Hoop, but it was more than ten feet deep. Fortunately he was able to get out with the help of his friends, but dislocated his shoulder. Sinkholes don’t only happen in Illinois. In Massachusetts a seventeen foot sinkhole was discovered early in the morning. The most dramatic and alarming sinkhole appeared two weeks ago in Florida. While a man was sleeping in his bed a giant sinkhole opened up under his home’s foundation. Before he was able to react, the man and his bed were swallowed up into the sinkhole, which collapsed around him before help could arrive. Despite these scary and dramatic examples, one scientist was quoted as saying “ I don’t believe we’re having anymore today that we’ve had before.”
Sinkholes have a huge affect on humanity. Scientist have been trying for years to figure out a way to determine when they happen. However, sinkholes usually occur in layers of soluble bedrock. Most of this bedrock is located around the southern states. It is very scary, and unusual that a sinkhole occurred in Massachusetts. It would be very rare that a sinkhole could occur in New York due to our rock soil composition. Sink holes generally occur in urban areas like New York due to water main breaks or sewer collapses when old pipes give way. However, if i lived in Louisiana there would be a greater chance that there could be a sinkhole. Sinkholes can also form from human activity. For instance a collapse of abandoned mines.
I thought this article was really interesting. However, I think the author could have elaborated more on the different sinkholes. The author would only state one or two facts about the different incidents of the sinkholes. I had to do outside research for the causes and the different occurrences. I did think there were some good points to the article. For instance, I thought it was interesting how the author interviewed a scientist. It was interesting hearing his point of view on the sinkholes, and how he thinks that they are not typically a big deal nor are they occurring more often than in past years.
