Hi Aleks,
What you described sounds a bit like the plot of the movie "2012." The main idea behind this film is that a massive solar flare causes an increase in the solar neutrino flux that heats the Earth's core, causing catastrophic earthquakes, tsunamis, and volcanic eruptions. I saw this movie on DVD a while back and the bad science in it made me cringe. The effects of the solar neutrinos in this film violate the laws of physics. The problem with the scenario described in the film is that neutrinos are very weakly interacting particles. Neutrinos do not carry an electric charge, so they are not subjected to electromagnetic forces. They are only affected by the weak subatomic force and gravity, which is very weak on subatomic scales. As a result, neutrinos can travel very large distances through matter without interacting with it at all. Because their interactions with normal matter are so weak, neutrinos are very hard to detect. In fact, there are probably billions of neutrinos passing through your body right now, but you do not notice them at all because they are so small and do not interact with matter very much. Solar neutrinos only transfer a very small amount of their energy to any material that they pass through. Even if the flux of solar neutrinos were to increase dramatically, it is unlikely that they would cause the kinds of catastrophes featured in the movie "2012."
