Wow. I never realized that this happened.
The Feb. 27 magnitude 8.8 earthquake in Chile may have shortened the length of each Earth day … by about 1.26 microseconds. Source: NASA – Chilean Quake May Have Shortened Earth Days.
What does this mean? Is the earth spinning faster? Some answers are around on the web, but not many.
A shortened day could mean sunlight shines on a spot for less time, and darkness would cover an area for less time too. I think what it would affect more than the clock though. I think gravity, surface temperature, climate, the moon’s orbit, satellites’ orbits, would be affected to name a few. Only (a shortened) time will tell.
