Oil workers report 'shaking' during North Sea earthquake
An earthquake has been reported in the North Sea by oil workers.
A 4.2 magnitude tremor was recorded about 149 miles east of Aberdeen yesterday afternoon.
The quake was registered at a depth of six miles.
The British Geological Survey (BGS) said on Twitter: "We have received a report from the Elgin-Franklin offshore field that this event was felt by several people on the PUQ offshore oil platform.
"The reports describe 'a moderate shaking feeling'."
A quake of that magnitude is considered light to moderate, with the likelihood of only causing minor damage.
In 2010, a 3.5 magnitude earthquake was detected in the North Sea about 155 miles east of Aberdeen.
