Swifties' dancing in Edinburgh sets off earthquake monitors

Fans at Taylor Swift's concerts in Edinburgh danced so hard that they set off earthquake monitors, say scientists.
According to the British Geological Survey the vibration was recorded by their monitors six kilometres (3.7 miles) away.
The British Geological Survey (BGS) said analysis of their seismograph data suggested that the energy "peaked" on the Friday night - the opening night of the UK leg of her tour.
BGS Seismologist Callum Harrison said: "Clearly Scotland鈥檚 reputation for providing some of the most enthusiastic audiences remains well intact!"
How do you record dancing power?

The British Geological Survey uses monitoring stations to record vibrations and movements in the Earth.
Seismic energy is what's released during an earthquake.
When the Earth's plates rub together, the movement can force waves of energy to come to the surface.
This is usually measured on something called the Richter scale, which tells us how severe an earthquake is.
Seismologist Mr Harrison added it was "amazing" to "measure the reaction of thousands of concert goers" using their technology.
"The opportunity to explore a seismic activity created by a different kind of phenomenon has been a thrill," he said.
Where is the Eras tour going now?
The Eras tour is currently in Liverpool before moving on to Cardiff for one night, then heading to London for three.
It then leaves the UK, heading to Dublin on 28 June and Amsterdam on 4 July.
Taylor's not quite done with the UK yet though - she's coming back to perform at Wembley Stadium in London in August.
