Tidal Quake: South Asian Tsunami likely caused by unique tidal forces

by Guy Cramer

One of the largest earthquake of recorded history occurred Dec. 26, 2004 00:59 GMT just off of Indonesia, causing a rift 700 miles long on the ocean floor resulting in a series of Tsunami's (Tidal Waves) which devastated shorelines of surrounding countries killing well over 100,000.

Was this a random event or was there a trigger for the massive earthquake?

The time around Dec 26th, 2004 had a series of known astronomical events take place. On Dec 21st the Winter Solstice (Longest day of the year in the southern hemisphere). On January 2, 2005 the Earth is closest to the sun in the yearly orbit (3 million miles closer than on July 2nd). The Full Moon was on Dec 26th and the moon was at apogee (farthest point in the lunar orbit from Earth). The High tide for Dec 26, 2004 in Sumatra, Indonesia took place at 7:48 AM local time, the Earthquake took place at 11 minutes later at 7:59 AM Local time (00:59 GMT). 

These combined events meant that the Suns tidal effect was increased more than any other time of the year. The actual tidal influence of the Sun is 44% of that of the Moon as it's distance is that much farther away than the moon.

Winter Solstice: Dec. 21, 2004 12:42  GMT / UT
Lunar Apogee (farthest point of orbit to earth) Dec 27th 1:48 PM EST 2004 December 27 19:16 Moonís tidal effects can be up to 18% less than those at the average distance.
Full Moon  2004 December 26 15:07  The combined tidal effect of the Sun and the Moon is approximately 12% stronger
Earth Perihelion (Closest point of Earth's orbit to Sun) Dec 27th 1:48 PM EST 2005 January 2 00:37 Tidal effect for of Sun increased by some 5%.

When the Sun, Earth and the Moon all lie along a straight line, as at new and full Moon, the Sunís and the Moonís tidal forces pull in the same direction and cause high tides to be higher than average, and low tides to be lower than average. Parts of continent may rise and fall as much as 0.40m (16 inches) when the Moon passes overhead.

So while the Moon has a greater influence on tidal forces, the time around 00:59 AM GMT on Dec. 26th, 2004 the Sun had a higher percentage tidal influence than under normal circumstances. This tug of war on our tides between the Sun and the Moon was stronger between the two at this point and may have contributed to the extra stress to trigger the large quake. 

Tides and Seimic Activity

Fergus Wood, Phd., a former Research Associate at National Ocean Survey (and later NOAA), and the author of "THE STRATEGIC ROLE OF PERIGEAN SPRING TIDES IN NAUTICAL HISTORY AND NORTH AMERICAN COASTAL FLOODING, 1635-1976", published by NOAA in 1978, sent a copy of his book to the U.S. Geological Survey with a comment about possible tide/quake connnection. On pages 201-203, Wood points out that during six centuries (1635-1976), the greatest tidal force exerted on the Earth by the Sun and Moon was January 4, 1912. On that date the Earth-Sun distance was at a minimum (perihelion); the moment of the Full Moon was only 6.5 minutes away from an extreme minimum perigee.

Only two quakes are listed for California/Nevada during 1912-1913, with the strongest of these hitting near the California-Nevada border, close to Bishop (about 5.5M), which occurred on January 4, 1912, the day of the maximum tidal forces in six centuries.

Our Ion Ratio Algorithm www.superforce.com has accurately been predicting global air ion ratios since Jan 1, 2000, we have seen how this poorly understood relationship effects people, physically and mentally. What we don't disclose on the site is the severity of individual days. Eight different factors are placed into the formula to determine the outcome. One portion of the formula showed Dec, 26th 2004 was the most positive day by a factor of 4 for the entire 12 months of 2004. While we had not anticipated a strong cause and effect relationship with ion ratios and earthquakes, we did know of the potential for the ion ratios to influence animals before an earthquake.    

One of the geological experts on earthquake prediction revealed to a stunned group of geophysicists that his excellent prediction accuracy was due to his method of tracking the Lost Pet section of the San Francisco newspaper and seeing how many cats went missing from day to day. When there were sudden increases in missing cats, an earthquake seemed inevitable, the more cats missing the larger the earthquake. It has since been discovered that prior to an earthquake radio signals are emitted from the ground due to the high ionization caused by the increase in pressure.  This ionization is considered the most promising area of earthquake prediction research at this time. Animals, however, are more sensitive to these ion ratio changes than the current instruments are capable of measuring.  Cats hide when there is a danger present and go missing days before an earthquake.

The Lunar Parallax and Solar Parallax Inequalities

Both the Moon and the Earth revolve in elliptical orbits and the distances from their centers of attraction vary. Increased gravitational influences and tide-raising forces are produced when the Moon is at position of perigee, its closest approach to the Earth (once each month) or the Earth is at perihelion, its closest approach to the Sun (once each year). This diagram also shows the possible coincidence of perigee with perihelion to produce tides of augmented range.

The Moon does not travel on our ecliptic plane (the plane in which the Earth's orbit around the Sun lies) or we would have a lunar eclipse and solar eclipse each month. The Moon's orbit is inclined 5.145396į with regard to the ecliptic so as seen from the centre of the Earth, the Moon drifts up and down slightly more than five degrees in the course of each orbit. This means that the moon will have stronger and weaker effects which differ depending on the point of the inclination.

Graphic below: The Moon's center point on the Earth on Dec 25, 2004 at 16:59 GMT (8 hours prior to the earthquake) Note the geographic center of the picture is slightly above the epicenter. This is due to the place of the Moon on the inclination meaning the moon might have had a larger influence on this region 8 hours prior to the earthquake.

In conclusion: The human and financial cost of the Southern Asia Tsunami of 2004 should warrant further study by the NOAA and the U.S. Geological Survey to review the work of experts in this field such as Fergus Wood and James O. Berkland where predictable Tidal Forces are seriously considered by geophysicists and geologists as a cause and effect of tectonic shifts as a means for accurate earthquake prediction may actually be used.

Polarity shifts in Ion Ratios on increase/decreased pressures of atmospheric tides may also have some effect in this new area of research.
