Quake shifted Japan away from Korea: scientists

The massive earthquake that devastated northeastern Japan has shifted the country more than two metres away from the neighbouring Korean peninsula, scientists said on Thursday.

The Korea Astronomy and Space Science Institute (KASSI) said the Korean peninsula moved east up to five centimetres (two inches) while shifted some 2.4 metres (7.92 feet) east.

Consequently, the distance between the countries increased by more than two metres, the institute said.

The disputed Dokdo islands, also claimed by Japan where they are known as Takeshima, relocated furthest, moving five centimetres east, as the islands in the Sea of Japan (East Sea) are relatively closer to the epicentre.

The southwestern port of Mokpo drifted 1.21 centimetres.

"We are closely monitoring to see whether the shift was temporary or perpetual," a KASSI spokeswoman told AFP.

"But don't worry. You will never feel the change anyway," she said.

According to , the 9.0 magnitude also shortened Earth's day by just over one-millionth of a second and shifted the Earth's axis by about 6.5 inches.

I'd like to know if the shift in the earths axis increased or decreased earths tilt. No previous article has been clear on this.

This is interesting. Perhaps this distance should be more closely monitored as a predictive index.
If you visualize the Pacific plate pushing against/under the Asian plate, it is clear that the surface distance between Japan and the continent will decrease until stresses are relieved. Starting time, now!
