我只是习惯性地看了一下那个日本京都大学地磁指数网站。
地磁变动不算大，但连续有两个波谷，所以可能达到6级，3天之内。

如果那条线是接近y=0，则世界上基本上无地震。当然也不是100%，有时候青藏高原中
部和西部大地震发生前这条线不会有明显变动。但如果是青藏高原东部边缘大地震，则
这条线一定会有明显波谷，可以迅速降到-100甚至-200然后缓慢回升到0。

2nd derivative vs Day in June.
On June 7, there was a huge change in 1st deriv and 2nd deriv of DST. So
there'll be 5.5-scale earthquake. But between June 1 and June 7, the change
in 1st deriv was also significant. So xiaxie bumped up his prediction to 6.0
-scale.
Sorry my MS Excel level is still in the year of 1997.

发帖数: 10683 | 11 I have never learned new stuff in MS Excel ever since then.
Now my friend told me in order to find a white-collar job, I need to brush
up my MS Word, Excel, and PowerPoint skills.
So I will learn new stuff in MS Office.
