For the purpose of generating electricity, I would expect very low energy from these fields in any localized area - and thus no efficient way to capture a significant amount of that energy. It would be more or less comparable to generating electricity from existing background radio noise. As for the purpose of weakening earthquakes, this energy may as well have already left the system - it's propagating away from where the problem is. This article is like saying that exhaust from a car engine decreases air quality. You could harvest that exhaust but it won't affect the engine. If somehow you did have enough pressure and containment to keep the exhaust from leaving the engine at all, that would have some effect. But if we could do that EM fields over all of California, I think that would have bigger effects on the planet than weakening the occasional earthquake. That's like a Star-Trek-level of control over a planet.
