Fracking in Lancashire has been brought to a halt again after another earth tremor.
The British Geological Survey recorded a 0.8 magnitude earthquake in the region of the shale exploration site at 10.30 am this morning.
It's the second earth tremor of the same magnitude that halted the process on Friday.
That seismic activity was classed as a "red event" and Cuadrilla has paused fracking operations.
Micro seismic events such as these result in tiny movements that are way below anything that would be felt at surface, much less cause any harm or damage.
Work at the site was paused on Tuesday when a tremor of around 0.4 magnitude was detected.
At the time Cuadrilla said that was 'extremely low' and Frack Free Lancashire described it as a "worrying sign".
