Chile earthquake?

Another high magnitude earthquake just struck Chile, with a 8.8 magnitude. As of this time, reports have it that there is at least 6 casualties and will be rising, we hope not. Last time it was Haiti, now Chile! I don't know but is this really natural or there is something hidden in here which we are not aware of.These two countries are located just within the central and south america region just like Cuba and Venezuela and some other countries of course. We just hope that this earthquake stop devastating these countries.
