Another earthquake has hit Blackpool near the Preston New Road fracking site - and it's the biggest one so far.
Cuadrilla has stopped all fracking operations for 18 hours due to the 'red event' quake, which happened at around 11.30am.

The earthquake, which measured 0.8 on the Richter Scale, is the thirteenth recorded by the British Geological Survey, and is the biggest one recorded in the area since fracking began last Monday.
In a statement, a Cuadrilla spokesman said: "A micro seismic event of 0.76ML was detected just after 11.30am at Cuadrilla's shale gas exploration site in Preston New Road.
"Cuadrilla was hydraulicaly fracturing the shale rock adjacent to the horizontal well at the time and the seismicity is classed as a red event in line with the traffic light monitoring system regulated by the oil and gas authority.
"Operations have now paused for the next 18 hours during which seismicity levels will continue to be measured.
"The BGS records seismicity to one decimal place and therefore have recorded the event at 0.8ML.
"Micro seismic events such as these can result in tiny movements that are way below anything that could be felt at the surface, much less cause any harm or damage. Without sophisticated monitoring at Cuadrilla, they would not be detected. It is reassuring that the monitoring and traffic light system is working as it should."
Fracking is expected to resume at the site tomorrow morning.
