As for radiowaves from the sun, that causes ( i think) earthquakes.It's a theory

If they communicaat with a submarine, how do they receive a signal back? I mean that a sub has not that equipment like HAARP on board? Is it one way communication?
The HAARP transmitter generates strong radio waves in Alaska, some of which will propagate along the magnetic field lines of the earth, and fall upon the point 56.19± S, 173.80±E.
This transmitter can operate as a modulated ionospheric heater causing ELF/VLF waves to develop high above the site. Some of these waves are ducted and propagate along the magnetic field lines of the earth. They return to the earth, along with other possible triggered effects, at the magnetic conjugate point.

How does that get transferred downwards and how can it be directed?
ELF/VLF data are taken with the so-called AWESOME. These broadband, high-sensitivity (typically femtoteslas) ELF/VLF receivers consist of two orthogonal air-core loop antennae, measuring the two horizontal components of the magnetic field between 350 Hz and 47 kHz. Data is synchronized to GPS with inherent 200 ns accuracy. The receivers include RFI-suppression filtering at the input to reject HF signals.
GM inherently delivers 3 dB more HF power into the ionosphere compared to AM, yet provides a 7–11 dB enhancement, and is therefore more efficient by 4–8 dB, likely as a result of more efficient phasing of the heated region and utilization of the heating duty cycle.
Moore et al.  demonstrated the long-distance observation of ELF waves produced using the HAARP HF transmitter at a ground distance of »4400 km from the transmitter at Midway Atoll. Observations were shown to be consistent with a radiated ELF/VLF power of ~4-32 Watts from an ionospheric altitude of ~75-80 km [Moore et al., 2007].
