We need to know where it's heading so we can renew our wardrobe appropriately.

I'm hoping for some place just off the coast of Barbados.

Re: Minor earthquakes near Blackpool

I distinctly remember years ago at school my science and geography teachers telling us how the UK doesn't get earthquakes and never will.

Idiots.

I need a new signature... i'm bored of the old one!

Re: Minor earthquakes near Blackpool

I've only experienced one in Sheffield and I'd prefer not to experience another.

I believe it was this one.

The earth has moved for me a few times - and I've also experienced the occasional earthquake.  Wink

Neglecting the debate over fossil fuels vs renewables...

The magnitude of the reported tremors needs to put in context.

A 0.8 magnitude earthquake is tiny.

Earthquakes less than 1 are classified as microearthquakes.

https://en.m.wikipedia.org/wiki/Richter_magnitude_scale

The Richter scale is logarithmic so Strats 5.2 quake was thousands of times larger.

https://simple.m.wikipedia.org/wiki/Richter_scale.

If a 0.5 magnitude quakes equates to 5kg of TNT, then blasting during mining and tunneling would produce stronger microearthquakes.

Re: Minor earthquakes near Blackpool

One thing I was wondering about.

You're driving along a pot holed crumbling road (like everywhere). What sort of magnitude would the earthquake have to be before you would notice it?

You could drive through Blackpool.

A slate falls off a roof and kills you, due to a "microquake"

Would that satisfy you?

Sensible comments @RichardB. On LBC it was stated that as a precaution anything above 0.5 and work has to stop fro 18 hours to assess the situation. This apparently was done and permission given to carry on.

Re: Minor earthquakes near Blackpool

Last time they were fracking it resulted in a 2.3 magnitude quake on 01/04/2011.

Re: Minor earthquakes near Blackpool

Another tremor this afternoon again 0.8 magnitude. Work on site has been stopped until Monday.

The government is talking about raising the threshold to 2.

Stated on the radio this afternoon neither of the tremors were felt on the surface but picked up on underground sensors.

Re: Minor earthquakes near Blackpool

This government would like to set the threshold much higher.

It's up North & doesn't matter.

There are potential fracking sites all over the country.
