Presentation by Luis Sanchez at the 40th edition of the Madrid Astrology Congress. The event was held between June 6 and 8, 2025 at the Exe Convention Plaza Madrid hotel.

About the presentation “Precessional Astrology as an astrological predictive technique for Natural Phenomena”

Precessional astrology offers us a novel predictive astrological system never before used.

This system is based on the calculation resulting from dividing the 25,776-year precessional year by 12 (the zodiac) and then again by 12, providing us with the appropriate precessional units of measurement to gauge the timing of natural phenomena occurring on the planet and affecting humans.

When applied to any natural phenomenon, whether on a very large scale such as the climate changes of the last glaciation, the Lesser Dryas or on a smaller scale due to volcanic activity, earthquakes or solar flares, it calculates when is the year of repetition of the natural cycle of these events, serving both to predict them and therefore to prevent us before them.

Units of Measure to be used according to the necessary scale 1/ 25776 years = 1 Platonic Year or Eón 2/ 25776 years / 12 signs = 2148 years called Era 3/ 2148 years / 12 = 179 called Subera 4/ 179 years / 2 (Half of 1 Subera or Maximum Point of a curve of Subera) = 89 years called ½ Up Subera.

When applying this technique to the last glaciation of 25,000 years, we see how all the periods cataloged by geologists with the Hindu Yugas, with solar flares and with the collapse of civilizations, are ordered in a natural way, in a timeline where it can be seen that they always follow the maxima or minima of the Eras and respond to the 2506-year pattern of the Suberas. When applying the measurement of 2148 years of axial precession to the other 2 most important cycles of the planet, Absidal precession and Obliquity, the result is that they are divisible by 2148 years giving a PERFECT INTEGER (Apsidal Precession 52 Axial Eras and Obliquity 19 Axial Eras) ​​demonstrating that Axial Precession governs Obliquity and Apsidal thus demonstrating that the “Milankovitch’s theory” about how the axial tilt is responsible for the Earth’s climate is correct.

Applied to volcanoes and earthquakes since 2022/ Applied to the 10 most powerful solar flares

When applying this technique to the earthquakes activated since 2023, we see that they repeat the cycle of precession with respect to previous activities and between them in a familiar line.

• Earthquake in Turkey/Syria in 2023.
• Earthquake of Aleppo 1138 AD 2023 AD – 1138 AD = 885 years 885/179 = 4.95  5 times Repeat cycle.
• Earthquake in Turkey 1939 AD 2023 AD – 1939 AD = 84 84 years/89.5 = 0.94 ½ over Repeat half cycle.
• Earthquake in Turkey in 1668 AD 2023 AD – 1668 AD =355 years 355 years /179 = 1.99   2 suberas repeat cycle.
• Earthquake in Morocco 2023.
• Morocco-Spain earthquake in 740 a.c. 2023 AD + 740 BC = 2763 years 2763 / 89 = 31.04 31 medias suberas complete cycle.
• Lisbon Earthquake 1755 AD 2023 AD – 1755 AD = 268 years 268/89 = 3.01 3 exact averages above.
• Among them: 2023 AD (earthquake of Morocco) – 1755 AD (Lisbon earthquake) = 268 years 268 years / 179 (1 subera) = 1.4999 suberas 1 subera and ½ exact or 3 half suberas exact.

By applying this technique to volcanic events, scientists have verified that those of magnitude 7 occur approximately once every 625 years (625/179=3.5 Suberas), while those of magnitude 8 occur every 14300 years (14300/179=80 Suberas). When applying this technique with the activation of volcanoes in Iceland in 2023/4 (bottom chart) it is seen how the 8 most powerful eruptions in history are intertwined by precession in 2 families and converge in 2023 and 2073, wanting to present in the presentation of this 40th edition of the Iberian Congress this example and others such as solar flares (bottom chart), of which 2 of the 10 most powerful recorded in history converge in 2025 and 2026.
