Geological surveys have long used small detonations in conjunction with an array
of microphones - maybe there is no plan for LF radiation, but if there is, we'd
all be interested to see the details

Subject: LF: gas es oil cales
LF/MF
Seemingly some cables are being layed through out some parts of the UK for GAS
es OIL exploration. These cables will will carry a signal to penetrate the
earth and detect if gas/oil is below. There will also be some small explosive
charges at times in the earth and these will be detected also by the cable and
fed to a master station.
Does anyone know what frequency is transmitted down these cables or mode of
transmission PULSE etc
This could be a source of QRM for the LF/MF radio amateur and most people do not
know it is taking place and wondering where the QRM is coming from.
There will be a network of cables for hundreds of miles lying on fields and
ditches etc while the exploration is going on
