Satellite experts have produced data that shows parts of Manchester have risen by 7 cm in 11 years.

Following recent earthquakes in the city, the NPA Group, a satellite mapping company, revealed that some areas are rising by 6 mm or more every year.

It is thought that earthquake activity in Greater Manchester is causing the uplifts, something that property developers and insurers may have to start taking into consideration.

Adam Thomas, project consultant, said the correlation between the ground movements and the tremors is compelling.

"We are investigating this with the British Geological Survey (BGS) and hope to make a further announcement soon," he remarked.

Central and south-east Manchester were shaken by six tremors last month, one of which measured 2.5 on the Richter scale.

And between October 2002 and January 2003, around 150 tremors hit the city-region, including one that measured 3.9 on the scale and was felt throughout Greater Manchester.
