NASA scientists say the massive earthquake that shook Chile last week may have tilted our planet’s axis by 3 inches. This new tilt will actually shorten our days by 1.26 microseconds. A microsecond is one-millionth of a second.
Natural disasters have tilted Earth before. In 2004, a 9.1-magnitude earthquake that caused a monstrous tsunami in the Indian Ocean shortened the length of our days by 6.8 microseconds.
