*** Processes such as the movement of tectonic plates relative to one another cause strain to build in fault zones until their rock layers are about ready to fracture.

*** As the Earth and moon rotate about their shared center of mass each month and the Earth and sun do the same each year, the Earth is accelerated in different directions.

*** The rate of that acceleration is constantly changing. And that introduces constantly changing amounts of stress into the Earth's crust. During time windows when that stress is at a high point it can help weaken already strained fault zones.

*** As the Earth rotates on its North and South Pole axis each day relative to the sun and to the moon additional stress waves or "Pressure Waves" travel from east to west. Crests and troughs associated with them can at times be around the same locations as ocean tide or Solid Earth Tide crests and troughs.

*** When a Pressure Wave crest or trough hits one of those already strained fault zones at just the right angle it can weaken it sufficiently that it begins to fracture, and an earthquake occurs.

*** Stress inducing acceleration time windows appear to last for several days. There are two major windows each month about 14 days apart. And there are two less important windows about 7 days after each of those major windows.

*** Stress inducing Pressure Wave time windows may be active for perhaps 10 minutes at a time. And a simplified picture would propose that there are usually four of those windows, roughly 6 hours apart each day.

ADDITIONAL INFORMATION WHICH WAS DISCUSSED IN THAT FIRST REPORT

It discussed the possibility of comparing MICA computer program related data and Solid Earth Tide computer program data. What I wanted to determine is if that is possible. Discussions regarding that subject matter which I have been having with geophysics personnel indicate to me that such comparisons cannot be easily made for the following reasons:

MICA program data relate to the movement of the Earth as a rigid object in space as it is affected (primarily) by the sun and moon gravities. And program data are essentially for all locations on and inside the Earth at the same time. Solid Earth Tide data programs generate data for specific locations on or inside the Earth as they are affected by various tides etc. In theory the two types of data are linked as the tides result from the sun and moon gravitational pulls on the Earth. But for most purposes those data would have to be regarded as being independent of one another.

THEORIES REGARDING HOW EARTHQUAKES ARE BEING TRIGGERED

It appears to me that one of the main reasons that scientists have never been able to propose a widely accepted theory for how earthquakes are being triggered is because there are so few who have the expertise in the various, necessary areas of science. In part to demonstrate that this is the case I am going to ask the following question. In my personal opinion, any geophysicist should be able to answer it. But I would be a little surprised if any could without first consulting with an expert in this field.

QUESTION: With the "acceleration" type data which Solid Earth Tide programs generate, do those data refer to the force of gravity at the specified location? Or are they referring to acceleration related to the up and down movement of the ground associated with the Solid Earth Tide?

My own best present guess is that they are referring to ground movement related acceleration rather than changes in the force of gravity.

WEATHER RELATED COMMENT

Something which I have discussed in the past is the possibility that solar storm (others have also proposed this) and perhaps earthquake fault event related geomagnetic storm activity might at times be affecting the Earth's weather systems, perhaps even encouraging some tornados to be spawned. I cannot point to any specific groups doing research on this, but I have been hearing rumors that researchers are beginning to look into the possibility that the solar storms, at least, are at times affecting the weather through a geomagnetic storm link. The following is an older report which discusses this subject:
