Yes. It was a cold day! I was warm because I was running around the hillside teaching. 😁

How useful is this method/technology for archeology, specifically for searching for voids and tunnels?

Thank you Christos. It was a casual lecture oven to Geography students on a cold wet day in the north of England, on the surface of a major landslide site at a place called Mam Tor.

Truly informative and useful explanation. Thank you. I have a question dear David. As far as I know, electrical resistivity measurements are ideally applicable where there are relatively negligible subsurface variations both horizontally and vertically. however such an ideal situation is in fact unattainable. How much deviation from this ideal condition can be allowed? what about non-homogeneous conditions? Can we trust the result for example on the basin slopes (basin edges) where the horizontal layering between electrodes can be violated? Many thanks.

Hi Juzer. I'm the guy in the video - lecturer in Forensic and Geographical disciplines at LJMU, Liverpool, England. Giuseppe is correct - specifically it is the Syscal Pro 72 - which means it has up to 72 electrodes available. It is my very favourite piece of equipment. I hope you have the chance to benefit from this wonderful, exciting area of science.

No. Resistance is the more correct term because we measure the ratio of current to potential to calculate resistance but we then infer resistivity with reference to the electrode geometry. The value we measure can be exactly interpreted as resistance (or, indeed, impedance, though these are usually DC measurements) but the inferred resistivity value is only ever an approximation which requires certain assumptions. This is why we refer to it as 'apparent' resistivity.

Hi Ikenna, I'm sorry I didn't see your request sooner. Yes, you can contact me by Skype. Please find me at LJMU, Liverpool online (just search for David Jordan LJMU) so you can see a bit more about me. Where do you live and work? 2hat is your interest and application for ERT? Greetings from Liverpool, David
