r/conspiracy aside, looks like the redditor's main theory is that there is some sort of casual link between solar flares and earthquakes. Should be an easy thing for a data scientist to debunk or validate...
He predicted an earthquake in the Philippines and other areas that didn't happen 2 months ago and one in New Zealand 1 month ago. He also made a prediction for a 9.0 earthquake in Nepal after the eclipse and slowly dropped the number over the days to fish out a "prediction". He was also hedging his bets on this earthquake and was giving preference to Japan, not Mexico.
The guy's a charlatan that was basically throwing predictions at the wall till they stuck and is now hoping no one notices his failures.
I disagree. I've read some of his forecasts and he's getting better over time. He put Mexico within the sphere of possibilities.
I think there's something to his solar flare theory. It may not be the only the only piece, but it seems to be a piece. He'll have an uphill battle to fight but it's fun to read his stuff.
