Hi,

While browsing I came across this short but -i think- a very well written article. I think it is a great read. It has interestingly wide coverage -especially when you consider how short the article is-. Especially o get you interested in sysmic prediction systems.

By the way, the article has some tilt towards Robbins TBM and I am admittedly an inside out Robbins TBM fan. But it definitely should not stop you from enjoing this article!
