Did you know? Japan experiences 20% of the world’s most powerful earthquakes. I didn’t know that until I read this article, though I knew they got quite a few. And as you can see, what with the country being mostly composed of volcanoes and nuclear power plants, it makes sense that they’d have the world’s most advanced seismic activity warning system. With the five they’ve just dropped, it now includes nine deep-sea ground probes and five tsunami detectors.
They’re connected through a fiber optic cable system and monitored from a secret undersea headquarters. Actually — I’m being informed now that they are actually monitored from a normal, above-ground observation center. Sorry, I get carried away sometimes.

I wonder how their seismic network compares with those set up in other countries? Have they ever worked with or approached QuakeFinder in CA to further their research into precursors? You’d think their government would be very interested in trying to find a way to know a quake is coming BEFORE the shaking. Seismic sensors will only tell you once it has begun.
