Earthquake Shortens Time of Day


Recently many people have heard about the earthquake that has occurred in Haiti, but on the other hand, a more recent earthquake has occurred in Chile and was much larger than the one in Haiti. Scientists have now found that because of this massive earthquake the time of day has decreased. No need to worry, it was only by 1.26 microseconds. Even though this is not a significant amount of time this change has astonished many scientists. Chile is surrounded by the Nazca and South American plates and these two plates always collide with each other constantly. This earthquake occurred because plates started to move suddenly. From this earthquake the sudden movement of the plates to the center of the earth happened, it changed the mass of the earth. When the mass inside of the planet moves around the way the earth tilts may also change. This change is the cause of the change in time because the way the earth spins determines time. When I read this article I was completely awestruck. The article started out saying that if you may be feeling that there's just not enough time in the day it may be because of this earthquake. That made me want to continue reading for I always think the day is just too short. Throughout reading the article I learned that it wasn't a large time difference at all, almost not enough time to blink. Overall, I enjoyed reading about a different side of this earthquake other than it's destruction.
