Although this year seems to be an average year for earthquakes, they do seem to be large and frequent.

I'm a bit worried about the swarm under Yellowstone and the recent quake at lake Toba, both of which are supervolcanoes.

If they go off, it's bad news.That and the fissure in Iceland, which produces lots of florine salts, which are toxic. Lond silent volcanoes produce the most catastrophic eruptions, so look at Germany and France too.

In a solar minimum, techtonic activity does increase.

I'll keep a look out for new activity around the next full moon.

What odds "the big one" in the USA?
