It is "highly probable" that shale gas test drilling triggered earth tremors in Lancashire, a study has found.
But the report, commissioned by energy firm Cuadrilla, also said the quakes were due to an "unusual combination of geology at the well site".
It said conditions which caused the minor earthquakes were "unlikely to occur again".
Protesters opposed to fracking, a gas extraction method, said the report "did not inspire confidence".
Six protesters from campaign group Frack Off climbed a drilling rig at one of Cuadrilla's test drilling sites in Hesketh Bank, near Southport, ahead of the report.
I want to join a group called Frack Off hahaha

The way I see it, the fault would have moved anyway, the explosions just helped them release stress that was building up and could have lead to a more powerful eathquake had they not been 'forced'.
In other words, they did everyone a favour! Fracking ftw, are people really against it, for serious? What are their reasons?
