The devastating 9.0 earthquake in Japan has actually increased the coastline of the country by 13 feet eastward. That's at the epicentre and there was less movement further away from it. As well, scientists from NASA have calculated that the earthquake might have shortened the day on Earth by a couple of millionths of a second and tilted the planet’s axis slightly. Previous earthquakes have also affected the axis of the Earth and the length of our day. The Chilean earthquake last year shortened the day by 1.26 millionths of a second and moved the axis by about three inches.
