       EVALUATION REPORT

Initial Evaluation Of The Effectiveness Of
Mr. Shan R. Shanmugasundaram's
Sun Shadow Deviation Measurement Based
Earthquake Forecasting Procedure

And It’s Significance to Earth Science,
Geophysics & Seismology

Evaluation Criteria for Failure, Success, Practical Value & Scientific Value

The criteria I have used for these evaluations is as follows:

Ratings

Days

Lat./Long. (Degrees)

Magnitude (Ms)

Failure

Success

Scientific

<1.0

Total Value = Success + Practical Value + Scientific Value

 

Practical Value: The prediction could be used to provide seismic hazard monitoring departments within or close to the concerned region with information that would help them enhance their seismic monitoring efforts around and during the time windows for the expected EQs.

Scientific Value: The prediction would not be accurate enough to be useful as an EQ warning. However, it would be accurate enough to provide evidence that the observed SSD was linked with a temporary shift – tilting in the Earth’s North – South Pole rotation axis.
