Asteroids and volcanoes

In this post we’ll look at ‘confirmed’ volcanic eruptions in Italy in the 16th and 17th century with a known start date. In the astrological chart for each eruption the positions of asteroids Vulcano, Etna, Vesuvius and Stromboli are of special interest.


Asteroids Vulcano, Etna, Vesuvius and Stromboli are named after Italian volcanoes. These volcanoes are of course very, very old. The asteroids, that are orbiting the Sun, are also very, very old. But what about the metaphysical connection between volcano and asteroid, via the official IAU name? How old is that connection really?

Asteroids can’t be seen with the naked eye. That's why their discovery started in the 19th century, using telescopes and other modern techniques.

Stromboli: discovered 24-9-1960 on Palomar Schmidt plates
Vulcano: discovered 11-10-1966 at Nauchnyj
Etna: discovered 24-3-1971 on Palomar Schmidt plates
Vesuvius: discovered 20-9-1973 on Palomar Schmidt plates


Retroactive effect
Perhaps the most baffling aspect of asteroid astrology is the retroactive effect of asteroid (or minor planet) names. Most asteroids have been discovered in the last 100 years. But if we want to retrace certain astrological correlations involving asteroids, we can actually go back in time much further, although there is a practical limit because of the precision of the calculated orbits.

A collection of 21 volcano eruptions in Italy in the 16th and 17th century illustrates the retroactive effect anecdotally. The charts are actually meant to illustrate two things:
- the retroactive effect of asteroid names;
- asteroids with similar potential meanings (in this case volcanic eruptions in Italy) can work together as a team.

This analysis focuses on the planets (including Chiron and the Galactic Center), four volcano-asteroids and six harmonic aspects: conjunction, opposition, trine, square, quintile and sextile. The idea is that eruptions correlate with relevant clusters of precise harmonic aspects (within 1 degree).

If a planetary pattern looks unstable or explosive, we might think of the vulcano-asteroids as elements that tip the balance or light the fuse. That's why a square between a vulcano-asteroid and Mars would be more significant than a sextile to Neptune.   

A very simple and subjective qualification (weak, medium, strong) gives some idea of the strength of the correlations.

Correlation score (total 21 charts)
Strong: 11 charts 
Medium: 3 charts
Weak: 7 charts
