Did you read my post? If an eclipse has an extraordinary effect on tides, why are the tides not highest directly under the eclipse on the day of the eclipse? Why is the tide 17% higher three months after the eclipse?
I guess you missed this too, posted by Blaine91555 earlier in this thread. There were no extraordinarily high tides in Mumbai.timesofindia.indiatimes.com...
Last week the SoI slammed the BMC for creating panic by declaring the5.05-metre high tide expected on July 24 as the highest of the century. Its research cell, in a letter to the civic agency, said tides of this height are normal for Mumbai.
You must have missed this too, posted by me. The high waves and resultant increase in local sea levels were caused by a storm at sea.

“There’s a storm out at sea. We can tell how violent it is, and how high the tide will rise from the wind,’’ says Khatim. “Did we know the tide was going to be this high today? Of course, the wind told us,’’ she retorts.
Scientific process? Demonstrate it for me. I've shown you an example of a higher tide occurring 3 months after an eclipse than occurred during an eclipse. Show me some cases of higher tides occurring during an eclipse as opposed to any other new moon. That's a beginning. Saying something happened at the same time as something else and that proves the one caused the other is not science. Even if there were a correlation (which there isn't), there is an important statement which is used when employing the scientific method; "correlation does not imply causality".

At what point did i say lunar activity does not have an effect, infact i believe i actually said that large tides are normally caused by the new/full moon earlier. I merely directed you to a post previously which you choose to ignore, thats fine. I didnt write that article in the link and never claimed too, maybe you should accuse that guy of a superiority complex.
Why so interested in my history fellow lowly ATSer? Surely my opinion is just as valid as yours. Im not the one with an axe to grind, but you seemingly have a strong dislike of skeptics joining up 2 weeks or so ago and giving us this little gem www.abovetopsecret.com...
There were scientists who made accurate predictions derived from a computer model. Although he was incorrect about a major tsunami, his assessment was correct in the shifting of tectonic plates as a result.

Q: Can the position of the moon or the planets affect seismicity?
A: The moon, sun, and other planets have an influence on the earth in the form of perturbations (small changes) to the gravitational field. The relative amount of influence is proportional to the objects mass, and inversely proportional to the third power of its distance from the earth.
The stresses induced in the earth by an extraterrestrial mass are proportional to the gravitational field gradient dg( r ) / dr
and NOT to the gravitational field g( r ).
g( r ) = GMm / r^2
thus:
dg( r ) / dr = -2 * g( r ) / r = -2GMm / r^3
Many studies in the past have shown no significant correlations between the rate of earthquake occurrence and the semi-diurnal tides when using large earthquake catalogs.
Several recent studies, however, have found a correlation between earth tides (caused by the position of the moon relative to the earth) and some types of earthquakes.
One study, for example, concludes that during times of higher earth and ocean tides, such as during times of full or new moon, earthquakes are more likely on shallow thrust faults near the edges of continents and in (underwater) subduction zones. Lunar or solar eclipses represent, of course, special cases of full and new moon, but do not cause any special or different tidal effects from full and new moon. Earth tides (Earth's surface going up and down by a couple of centimeters) and especially ocean tides (surface of the ocean going up and down by a meter or more) raise and lower the confining pressure on shallow, dipping faults near continental edges and in subduction zones. When the confining pressure is lessened, the faults are unclamped and more likely to slip. The increased probability is a factor of ~3 during high tides. But you must stop are realize that the background probability is, in general, very low in a given place and year (fractions of a percent), so that raising this tiny probability by a factor of 3 during high tides still results in a very tiny probability.
There have also been some small but significant correlations reported between the semi-diurnal tides and the rate of occurrence of aftershocks in some volcanic regions, such as Mammoth Lakes. (UC Berkeley)
