Earth's heat to produce electricity for homes in UK clean energy first Water super-heated by rocks will also provide the UK's first domestic supply of the critical mineral lithium.

Great news from #Cornwall, where #geothermal energy and lithium are now being generated from deep, hot granite. βš’οΈ

I still have my stencils. Yes, kids, this is what we used to use to label diagrams before computers.

Used to use a combination of these and Letraset dry transfer lettering.

In the UK, near-surface geophysics comes under the purview of the Geological Society of London where as solid-earth geophysics comes under the Royal Astronomical Society. Costs me a bloody fortune in fellowship fees every year being a fellow of both.

Depends on background I think. My degree was geology but doctorate in geophysics. My PhD advisor was from a physics background. He wouldn’t consider himself a geologist but I do consider myself one.

I’m wondering if the official location / origin time is a bit off for this event. All the UK records that I have seen have the P and S predicted times about 4-5 seconds ahead of the actual arrivals.

I was finishing my PhD on earthquake source mechanics when the Hasegawa and Kanamori paper came out. I quite liked the idea at the time that it was a single-couple event caused by the landslide.

So good to be outdoors supervising a GPR survey today, but why do I always get asked to do this stuff in winter rather than summer?

A lecture on geohazards in the Peak District by Vanessa Banks of the BGS last week attributed it to the volcanic ash layers between the limestones.

Can understand Bowland Shales and Coal Measure marine bands, but the Limestone Peak is unusual I think.
