Mars-Jupiter Effects on Earthquakes

The 1958 Lituya Bay earthquake occurred on July 9 at 22:15:58 with a moment magnitude of 7.8 to 8.3 and a maximum Mercalli intensity of XI (Extreme). The strike-slip earthquake took place on the Fairweather Fault and triggered a rockslide of 40 million cubic yards (30 million cubic meters and about 90 million tons) into the narrow inlet of Lituya Bay, Alaska. The impact was heard 50 miles (80 km) away, and the sudden displacement of water resulted in a megatsunami that washed out trees to a maximum elevation of 1,720 feet (524 meters) at the entrance of Gilbert Inlet. This is the largest and most significant megatsunami in modern times; it forced a re-evaluation of large-wave events and the recognition of impact events, rockfalls, and landslides as causes of very large waves.

At that time, a Mars (22 Aries 33) - Jupiter (22 Libra 23) opposition was aligned with the nodal axis of 27 Libra/Aries. Naturally, the Nodes, being the places where the Moon's orbital path crosses the ecliptic, are points where the gravity of the Moon is at its maximum when conjoined with the position of a planet, by way of declination. In this particular instance, the Moon added more mass to the combined gravitational pull :

Since a tsunami can be caused by volcanic eruptions (the megatsunami that reached a height of 853 feet/260m in Spirit Lake, Washington, USA was caused by the 1980 eruption of Mount St. Helens), it is possible that the gravitational effects of relatively nearby planets, when increased by the position of the Moon, can be responsible for the triggering of tectonic shifts.

If this is so, it might be possible to predict the dates of future megatsunamis if preceded by irregular seismic activity.

Mars-Jupiter oppositions occur about every 27 months or so, so there would not be that many to check, to see whether the opposition straddles the ecliptic as it did in 1958. If dates of these aspects indeed coincide with increased seismic activity for a particular area, it could be a method to give early warning emphasis to 'strike-slip' tectonic potential. The most recent isolated Mars-Jupiter opposition of July 29, 2021 was perpendicular to the Nodes, hence it would theoretically not have been of much interest.

By way of contrast, the next opposition, October 23, 2023, falls much closer to the nodal axis, and in addition, the gravitational pull of Mars is accompanied by that of Mercury and the Sun :

So, if there are a few smaller tremors preceding that date, it could be a good time for astrologers in that area to plan for a weekend in Vegas.

It would appear that the Mars-Jupiter conjunctions could also indicate periods when megatsunamis take place, for example, the tsunami in Spirit Lake, Washington, USA began with seismic activity that began on March 27, 1980.

On that date, Mars was at 26 Leo, conjoined by the Node at 27 Leo and Jupiter 4 degrees away at 1 Virgo, possibly initiating the May 18 eruption of Mount St. Helens, which created a megatsunami of 853 feet (260 m).

Obviously, a lot more research would be required to validate this possibility, but it does seem to be coincidental given the relative proximity of these planets. Obstetricians would probably disagree, but the planets affect Earthly activities, right?
