In what's being seen as a landmark case, an Indian woman has legally annulled a marriage that her parents arranged for her when she was a child. Laxmi Sargara, who is now 18, was married at the age of one to a three-year-old groom in the state of Rajasthan. Jo Jolly reports.

一名印度妇女通过法律程序解除了幼年时父母为自己安排的婚姻，这件案例被视为一个里程碑。在拉贾斯坦邦，今年18岁的Laxmi Sargara一岁时，就被嫁给一位三岁的新郎。Jo Jolly报道。

The teenager only found out about her marriage this month when her parents told her she would have to move to her in-laws' house. After asking a local social worker for help, Laxmi was able to persuade her husband to sign a legal document to annul the marriage and have this verified by a government official. Child marriage is illegal in India but is still common in many rural areas. Campaigners hope this case will encourage others to fight against the practice.

本月，Laxmi的父母告诉她必须搬到夫家去住，她这才知道自己的婚姻大事。Laxmi向当地的社会工作者求助，成功劝说丈夫签署法律文件终结婚姻，并得到政府官员的批准。童婚在印度为非法，但在许多农村地区仍很普遍。

Scientists at a German research institute say satellite data from Global Positioning Systems, or GPS, could be used to provide much faster tsunami warnings. The scientists say they've analysed data gathered from over 500 GPS stations at the time a devastating earthquake hit Japan in March last year. They say it could have been used to predict both the correct magnitude of the quake and the size of the resultant tsunami in just three to four minutes, faster than traditional methods.
