0.Information on Sumatra EQ and Tsunami is uploaded at Menu-0.
１．Present Status: - Side anomaly was observed once on 1/4.
２．Anomalous Information： (1) A middle class EQ (5.0<=M<6.0) at Tohoku or Hokkaido
is predicted to occur by 1/11 depending on the following reasons;
*1 As frequency of anomaly observation is low (only once), EQ occurs far place from Sagamihara.
*2 As polarity is -, EQ occurs at Tohoku or Hokkaido, not North Kanto.
*3 Potential and length of discharging time shows middle class.
*4 Preceding time of middle class EQ will be about 1 week.
(2) + side anomalous signal on Tree-2 at around 6 O'clock 1/2 may be precursory signal
for very small EQ around south Kanto or Izu Islands within 4 days.

-1. To all visitors, A happy new year!
Many of big disasters continued last year.
I pray with you for the far and near bliss of the dead which passed away domestic and overseas.
I pay a visit with you also to people on the way of revival from damage.
I hope to contribute for that an earthquake sign electromagnetism phenomenon may be increasingly developed as practical use information on earthquake disaster prevention by multi-system and multi-point observation this year.
Every one, shall we do our best together?

0.Review for 12/8 anomaly is revised, please refer to Menu-1E.
１．Present Status: - Side anomalous signals were often observed on 12/15.
２．Anomalous Information： The following deleted comment is revised as follows;
(1) Distance to the epicenter is not obvious as frequency of anomaly is unstable.
(2) As potential is high, these anomaly may be precursory signal of middle class EQ (M<6.0) which occurs near from observation post, or large class EQ (M>6.0) which occurs far from Tokyo.
(3) Preceding time will be within 7 days in case of middle class, or within 10 days if large class.
(4) Therefore, these may be precursor of middle class EQ around KANTO or TOHOKU district by 12/22 or large class EQ around HOKKAIDO by 12/25.
I presume that these anomalies are precursory signals of small scale (M<5) earthquake around KANTO district within 2 days, because anomaly appears frequently, potential is low and preceding time of small scale earthquake is not so long.
3. Safety Information: No anomalous data which may be precursory signal for big earthquake within 24 hours around Hokkaido, Tohoku, Kanto districts and Izu islands is observed.
