The Astrological Weather During the Aberfan Disaster: A Somber Reflection
The Astrological Weather During the Aberfan Disaster: A Somber Reflection
There are events in the history of Wales so devastating that they alter the landscape of a community forever, not just physically, but in the collective memory of a nation. The Aberfan disaster of 21 October 1966 is one such event. On that Friday morning, at approximately 9:15 a.m., a colliery spoil tip on the mountainside above the village of Aberfan, near Merthyr Tydfil, collapsed. Over 150,000 cubic metres of water-saturated coal waste cascaded downhill, engulfing Pantglas Junior School, 18 houses, and part of the neighbouring secondary school. 144 people were killed. 116 of them were children, most between the ages of seven and ten, sitting in their classrooms on the last day before half-term.
This article is not an attempt to explain or justify that tragedy through astrology. No chart can account for the suffering of those families, and nothing in the sky that morning caused a tip to move. The causes were entirely human: negligence by the National Coal Board, ignored warnings, and a spoil tip built on top of natural springs despite the known risks. What we can do, with due sensitivity, is examine the astrological weather of that day and reflect on what practitioners of mundane astrology might observe in the planetary patterns present during one of Britain's worst industrial disasters.
The Facts of the Day
It had been a wet autumn. During the first three weeks of October 1966, 6.5 inches of rainfall fell on the valleys around Aberfan, with nearly half of that arriving in the third week alone. Tip 7, the only active spoil tip on the hillside, had been started in 1958 and stood 111 feet high by the time of the disaster. It sat, in contravention of the Coal Board's own procedures, on ground riddled with underground springs that had been marked on Ordnance Survey maps since 1874.
Workers arriving for the morning shift at 7:30 a.m. noticed the tip had subsided overnight. By 9:15, it gave way entirely. A wall of black slurry, travelling at an estimated speed of over 80 miles per hour according to some reports, hit the village below. The children at Pantglas Junior School had just returned to their classrooms from morning assembly. They had been singing "All Things Bright and Beautiful." A clock found in the wreckage of a nearby house stopped at 9:13 a.m. It was later donated to St Fagans National Museum of Wales, where it remains today.
The last child pulled alive from the school emerged at 11:00 a.m. Bodies were still being recovered a week later. The final victim was found on 28 October.
The Chart of the Moment
For those who study mundane astrology, the planetary positions on 21 October 1966 present a picture that, viewed through an astrological lens, contains several configurations worth examining. We should be clear: astrologers who work with event charts do so speculatively, looking for symbolic correspondences rather than causal mechanisms. The positions detailed below are drawn from published ephemeris data for the date.
The Sun at 27° Libra
The Sun was in the final degrees of Libra, approaching the cusp of Scorpio. In mundane astrology, the late degrees of any sign are sometimes considered to carry a sense of culmination or crisis, as though the energy of that sign is reaching its limit. Libra, a sign associated with balance, justice, and fairness, was nearing its end. What followed the disaster, the inquiry and the grotesque injustices visited upon the bereaved community, would prove that any notion of balance or fairness was painfully absent. The subsequent tribunal placed blame squarely on the National Coal Board and nine named employees, yet controversially, the Board was permitted to take £150,000 from the public disaster fund to help pay for the removal of the remaining tips. It was not until 1997, more than thirty years later, that the Blair government returned that sum.
The Moon at 24° Capricorn
In traditional astrology, the Moon in Capricorn is said to be in its detriment, a placement where the Moon's natural qualities of nurturing, emotion, and care are constrained by Capricorn's associations with structure, authority, and cold pragmatism. For those who read such symbolism, a debilitated Moon on the morning that 116 children died carries a bitter resonance. Capricorn is ruled by Saturn, the planet of institutions and responsibility. The Moon here might be read as the emotional life of a community being crushed under the weight of institutional failure.
The Moon at 24° Capricorn was also in close opposition to Saturn at 24° Pisces. In astrological tradition, a Moon-Saturn opposition can signify grief, loss, restriction of emotional expression, and the cold hand of authority bearing down on vulnerable people. Saturn in Pisces, in this reading, suggests structural failures (Saturn) in conditions involving water (Pisces), an almost uncomfortably literal correspondence for an event caused by water saturation of an improperly sited coal tip.
Mercury at 20° Scorpio
Mercury, associated in astrology with communication, messages, and the activities of young people and schools, was in Scorpio. In mundane astrology, Mercury in Scorpio can represent hidden information, concealed dangers, or truths buried beneath the surface. The National Coal Board had been warned. Residents had complained to Merthyr Tydfil County Borough Council as far back as 1963 about the danger from coal slurry being tipped behind the schools. Correspondence between the council and the Coal Board continued from July 1963 to March 1964. No meaningful action was taken.
Mercury was also forming a sextile aspect to the Uranus-Pluto conjunction in Virgo, a link that, in astrological symbolism, could represent sudden, devastating communication or news relating to a dramatic structural collapse.
Venus at 22° Libra
Venus in its domicile sign of Libra would typically suggest harmony and beauty. Its presence on this day sits in stark contrast with the reality. For those who study astrology, Venus here might represent the community itself, the village life, the love of families, the children at school, all of which were shattered in a matter of minutes. Venus was also square to the Moon in Capricorn, suggesting, in astrological terms, a painful tension between what is valued and loved and the harsh reality of institutional neglect.
The Uranus-Pluto Conjunction in Virgo
Perhaps the most significant generational aspect of the 1960s was the conjunction of Uranus and Pluto in Virgo, which was exact three times between October 1965 and June 1966 at 16° to 17° of that sign. By October 1966, both planets had moved to approximately 19° to 20° Virgo, but remained closely conjunct. This was a once-in-roughly-125-years alignment, and it defined an era of upheaval, revolution, and the challenging of established power structures.
Uranus is associated in modern astrology with sudden events, disruption, and collapse. Pluto governs power, destruction, transformation, and what lies beneath the surface. In Virgo, an earth sign linked to work, service, health, and practical matters, their conjunction has been interpreted by astrologers as representing a period where hidden structural problems in everyday systems would be violently exposed. The Aberfan disaster fits this description with terrible precision: a catastrophic, sudden collapse (Uranus) of buried material revealing systemic negligence and abuse of power (Pluto), connected directly to industrial working practices (Virgo).
Saturn at 24° Pisces
Saturn in Pisces is, in traditional astrology, a placement that brings the planet of structure and limitation into a sign associated with water, dissolution, and suffering. As noted above, its opposition to the Moon is striking. But Saturn in Pisces also connects to the theme of institutional (Saturn) failures involving water (Pisces). The tip that collapsed was saturated with water from underground springs. The rain in the weeks before the disaster had been relentless. Saturn in Pisces, opposing the Moon in Capricorn, paints a picture of overwhelming water undermining a rigid structure, with devastating consequences for the most vulnerable.
Neptune in Scorpio
Neptune, the planet of fog, illusion, and the unseen, was transiting Scorpio in October 1966. There is a grim detail worth noting: the morning of the disaster was misty. Villagers heard the ominous rumble of the collapsing tip but could not see it through the fog. The mist that filled the lower valley prevented anyone from seeing what was coming. Neptune in Scorpio might also, in this speculative reading, relate to the murky concealment of known dangers, the burying (Scorpio) of truth beneath layers of institutional fog (Neptune).
Mars at 4° Virgo and Jupiter at 2° Leo
Mars, the planet of action and aggression, was in Virgo, the same earth sign hosting the Uranus-Pluto conjunction. Though not in close conjunction with those outer planets, Mars in Virgo broadly reinforced the theme of forceful energy directed through earthly, physical channels. Jupiter in Leo, meanwhile, occupied a sign associated with children, creativity, and generosity. Its semi-sextile to Mars is a minor aspect, but Jupiter's placement in Leo, the sign most connected to children in the astrological tradition, on a day when 116 children were killed, is a detail that mundane astrologers might note with solemnity.
A Word About Mundane Astrology and Tragedy
Mundane astrology, the branch that studies world events rather than individual horoscopes, has a long tradition of retrospective analysis. Practitioners examine the charts of earthquakes, political upheavals, wars, and disasters, looking for patterns. Some astrologers in the Hellenistic tradition, the approach studied by the Wilfred Hazelwood Clinic's lead therapist Martyn J. Shrewsbury during his training with Chris Brennan's Astrology School, would approach a chart like this through the lens of sect, planetary condition, and the traditional rulers rather than the modern outer planets. Others, working in the psychological astrology tradition that Martyn also studies through the Mercury Internet School of Psychological Astrology, might focus on the archetypal dimensions of what these placements represent.
What both approaches would likely agree on is this: the chart for 21 October 1966 does not explain the disaster. It describes an astrological weather pattern, a set of symbolic conditions. The actual causes were human, knowable, and preventable. The tribunal's report made this devastatingly clear.
The Aftermath and the Memory
The response to Aberfan revealed both the best and worst of human nature. Thousands rushed to the village to help dig. Nearly 90,000 people donated to the disaster fund, which eventually totalled approximately £1,750,000, the equivalent of some £27 million in 2023. But the handling of that fund became its own scandal. The National Coal Board chairman, Lord Robens, initially claimed the disaster could not have been predicted, despite years of documented warnings. He did not visit Aberfan until the day after the disaster, having first attended his investiture as Chancellor of the University of Surrey.
Queen Elizabeth II visited on 29 October, eight days after the collapse. She later described her delay in visiting as one of her greatest regrets.
The children are buried at Bryntaf Cemetery, where two long rows of pearl white granite arches stand over their graves on the hillside above the village. Most were laid to rest at a joint funeral on 27 October 1966, attended by more than 2,000 people. The memorial garden now occupies the site where Pantglas Junior School once stood. In 2022, the cemetery, memorial garden, and the path of the slide were listed on the Cadw register of historic sites in Wales.
In 2016, on the 50th anniversary, Welsh composer Karl Jenkins premiered Cantata Memoria: For the Children, a choral work with a libretto by Mererid Hopwood, commissioned as a tribute to those who died.
Reflection
Astrology asks us to consider the relationship between the movements above and the events below. In the case of Aberfan, that consideration must be handled with the utmost care. This was not a cosmic event. It was an industrial disaster caused by negligence, indifference, and a power structure that valued coal production over the safety of the people who lived beneath its waste. The planetary positions of that Friday morning do not explain why 116 children never came home from school.
But for those who study the astrological arts, there is something to sit with in the chart of that day: the debilitated Moon opposing Saturn across the Capricorn-Pisces axis, the Uranus-Pluto conjunction in Virgo that defined an era of structural collapse and institutional reckoning, Mercury in Scorpio carrying the weight of suppressed warnings, and Neptune's fog obscuring what was about to destroy a village.
If mundane astrology has any value, it lies not in prediction or explanation, but in reflection. The chart of 21 October 1966 is a sombre document. It deserves to be read with the same quiet respect that one would bring to the white arches of Bryntaf Cemetery, standing in their rows on the Welsh hillside, each one marking a life that should have had decades more to live.
