earthquake activity

"SEEV" = Single Equivalent Earthquake Value. Method: Sum all ≥M4.5 EQ energy for each day, then convert energy value back to Richter notation. Richter devised logarithmic method to represent earthquake strength: 2x whole increments of Richter Scale = 1000x energy release. E.g. M2.0 -> M4.0 = 1000x energy increase from former to latter. A single increment of Richter Scale represents 31.62x energy release. Why this number? Because 31.62 = 10^^1.5 | 2 x 1.5 = 3 | 10^³ = 1000.

The large spikes are highly predictable (≥80%) to window of ±3-days, if you know what data to look at and understand the cause. 'Earthquakes are impossible to predict' just as rocks (meteorites/asteroids) did not fall from the sky until the latter half of 20^th century, when dogmatic science caught-up with reality, 'recognised' this phenomenon was real, understood the cause, and a multi-discipline revolution ensued.

Note: Large (≥M6.5) earthquakes are normal phenomenon, often occurring deep in remote, unpopulated, places and infrequently causing headline catastrophes if a 'direct-hit' earthquake ≥M6 strikes a large conurbation or a tsunami is caused and strikes coastal regions, while remembering Earth has water:land ratio of ± 71:29.

orbital mechanics

It is worth mentioning that Earth's orbit is slightly elliptical. Earth's perigee to Sol (minimum distance = maximum gravity load) occurs 4-JAN yearly, with apogee (minimum gravity load) 6-months later. Earth's moon, Luna, also has three-dimensions to its orbit. Within a matter of weeks, Earth-Luna (x-axis) distance constantly changes within a range of approximately 220,000 miles to 255,000 miles, in addition to declination (y-axis) changes while Luna orbits around Earth (z-axis). Dynamic planetary gravity load (causal of tides) is not limited simply to phases of our moon. Both Sol and Luna have gravitational effects - proportional to aggregate orbital configuration. Sol mass: 1.99E30 kg. Luna mass: 7.34E22 kg. Do the calculations. :) Luna is responsible for exerting ± 0.5% of total gravity load at any given moment. Sol = 99.5%. In approximate terms, the gravity load drops-off by a factor of ±100 (10E-2) between each of Sol, Luna and Jupiter (±5au).
