Thank you EQF and Amit for your inputs. If EQF come across any precursor through his method, kindly let me know. Regarding Amit invitation, I visited his site and noted two dates lie on my predicted time frame as 7th October for 6.9M and 9th October for 6.7M. Since my tolerance level of prediction is always having plus or minus 1M in Magnitude (and 3 degree in location), let us watch for the result.
