pimg src=”http://cache.gawkerassets.com/assets/images/4/2010/03/500x_earth-jump.jpg” class=”left image500″ width=”500″ /Apart from a a href=”http://gizmodo.com/5482664/the-wrath-of-god-this-weekend”colossal tsunami/a, here’s another effect of the 66.6 exajoules liberated by this weekend’s earthquake in Chile: NASA’s Jet Propulsion Laboratory says that days will now be shorter because the quake shifted Earth’s axis by three inches./p
pThe changemdash;which can only be measured thanks to computer modelsmdash;will result in days that are 1.26 microseconds shorter than before. That’s 0.00000126 seconds shorter. There may have been more visible changes, like islands changing its position. One of them, Santa María, may have raised two meters after the shattering land move./p
pThis is not the first time this has happened, as every single earthquake has an effect on the planet’s axis. [a href="http://www.businessweek.com/news/2010-03-01/chilean-quake-likely-shifted-earth-s-axis-nasa-scientist-says.html"Business Week/a]/pbr clear=”both” style=”clear: both;”/
