Upsurge in big earthquakes predicted for 2018 as Earth rotation slows. Scientists say number of severe quakes is likely to rise strongly next year because of a periodic slowing of the Earth’s rotation. the Guardian. https://www.theguardian.com/world/2017/nov/18/2018-set-to-be-year-of-big-earthquakes Sloshing of Earth’s core may spike major earthquakes By Paul Voosen, Science, October 30, 2017 http://www.sciencemag.org/news/2017/10/sloshing-earth-s-core-may-spike-major-earthquakes Bilham, R., and Bendick, R., 2017.

Ive been through many earthquakes in California, some small some rather large and dangerous. None of those earthquakes made any noise. Last night, (I live outside of Helena Montana), both my wife and I were wakened up by ground shaking and then realized it was a very noisy earthquake! My wife was very frightened. I figured it was over, but was now wide awake. Then about 10 minutes later we both heard a very strange noise but no ground shaking. Figured it was a small aftershock. Then another 20 minutes or so and we heard another really loud noise comin our way the house begins to shake! After 2 more of those everything quited down. The most bizzar night I have ever experienced!!! Im gunna havta run into town and get the newspaper and see what and where. We dont get any local news. RB
