Was Tall el-Hammam Destroyed by a Cosmic Airburst — and Is It Biblical Sodom?

Background

Tall el-Hammam is a large archaeological mound in the eastern Jordan Valley, in Jordan's Amman Governorate, roughly 12 kilometres northeast of the Dead Sea. Kay Prag surveyed it briefly in 1975–76 and 1990, but sustained excavation did not begin until 2005, when Steven Collins of Trinity Southwest University launched a project that continued through 2016 and established the site as the largest Bronze Age settlement yet found in the southern Levant, with fortifications enclosing roughly 36 hectares and occupation layers running from the Chalcolithic period through the Roman era.

Two separate claims have made Tall el-Hammam unusually well known outside archaeology, and they are frequently run together in popular coverage even though they rest on entirely different kinds of evidence. The first, advanced by the excavation team since the project's early seasons, is that the site is the biblical city of Sodom. The second, published as a 2021 paper in the Nature-family journal Scientific Reports, is that the city's Middle Bronze Age destruction, a roughly 1.5-metre-thick layer of ash and carbon dated to about 1650 BC, was caused by a Tunguska-scale cosmic airburst. Scientific Reports formally retracted that second paper on 24 April 2025. This page keeps the two claims separate throughout, because the retraction resolves only one of them.

Is Tall el-Hammam Really Sodom?

The identification is a competing hypothesis, seriously held by the archaeologists who excavated the site but not accepted by most researchers working outside the project. Collins based the proposal partly on a reading of Genesis's description of Lot choosing to settle in the well-watered "circle of the Jordan," a phrase Collins argues points to the eastern, northern Dead Sea plain where Tall el-Hammam sits, and partly on the site's scale: whatever destroyed it ended the largest city in the region for centuries.

The identification runs into two well-documented objections. The first is chronological. The Bible's internal genealogies place Abraham, and therefore Sodom's destruction, several centuries before 1650 BC; at that date, on the Bible's own timeline, the Israelites were still in Egypt with the Exodus roughly two centuries in the future. Biblical scholars who otherwise treat the text's chronology as historically reliable, including Eugene Merrill, argue that accepting Tall el-Hammam as Sodom requires abandoning that chronology altogether. The second objection is geographical: the traditional location for Sodom, reflected in most biblical maps since antiquity, sits south of the Dead Sea, not northeast of it, and researchers such as Bill Schlegel argue the biblical text's own geographical details fit the southern location better.

The traditional southern candidates are Bab edh-Dhra and, roughly 20 kilometres further south, Numeira: Early Bronze Age sites on the Dead Sea's southeastern shore, both destroyed by fire, with mass above-ground charnel houses at Bab edh-Dhra and a burial site at Numeira showing fire that spread from the roof downward. Their destruction dates to around 2300 BC, several centuries earlier still than Tall el-Hammam's Middle Bronze Age layer, which is its own chronological problem for that identification. No candidate site north or south of the Dead Sea has produced an inscription, seal, or other direct textual evidence naming it Sodom; every proposal rests on inference from geography, scale, and destruction date rather than on a document that settles the question.

Robert Mullins, the excavation's own ceramic consultant, has been unusually direct about the project's evidentiary approach, telling reporters that the identification looked to him like "evidence being marshaled to support" a conclusion reached in advance, "as opposed to letting the site speak for itself." Other archaeologists who have examined the site's destruction layer, including Aren Maeir and Steve Ortiz, describe it as consistent with the kind of dramatic fire destruction documented at many Bronze and Iron Age Levantine sites, unremarkable in itself and not requiring either a cosmic explanation or a biblical one. None of this proves Tall el-Hammam is not Sodom; it establishes that the identification is a minority position resting on contestable inference, not a settled finding, and that the question is separable from, and older than, the airburst claim that later attached itself to the site.

What Destroyed the City? Two Explanations

The cosmic airburst hypothesis

The 2021 paper, authored by 21 researchers including several affiliated with the impact-focused Comet Research Group, argued that Tall el-Hammam's destruction layer contained evidence inconsistent with an ordinary fire: shocked quartz grains, pottery and mudbrick with surfaces melted into glass, diamond-like carbon, and melted minerals including platinum, iridium, and zircon, alongside temperatures the authors judged far beyond what Bronze Age technology could produce. The paper also reported unusually high salt concentrations, around 4 percent by weight, in the destruction layer, which it proposed explained centuries of subsequent agricultural abandonment across the lower Jordan Valley, sometimes called the region's Late Bronze Age gap, and offered as a physical echo of the biblical detail of Lot's wife turned to a pillar of salt. Framing the destruction as comparable in scale to the 1908 Tunguska event and to the melted glass found at the Trinity nuclear test site, the authors suggested a disintegrating asteroid or comet fragment exploded above the city, and proposed that an eyewitness memory of the event might have survived as oral tradition into the biblical account of Sodom's destruction by fire from the sky.

The paper drew heavy global media coverage on publication, exactly the kind of dramatic, scripture-adjacent claim that travels further and faster than the more cautious papers testing it later would. It also drew scrutiny almost immediately: within days, researcher Elisabeth Bik documented apparent image manipulation in several figures, and in February 2022 the authors issued a correction acknowledging that panels had been altered to remove features such as measuring tape, prior image labels, and visible fingers, replacing the affected figures and adding a fuller disclosure of their funding and Comet Research Group affiliations.

The conventional destruction explanation

Most archaeologists who have examined the evidence favour an ordinary explanation: fire, most plausibly from warfare, of the kind that ended many Bronze and Iron Age cities across the region without any cosmic assistance. Robert Mullins reported pottery from the destruction layer that he dated to the 16th century BC, later than the airburst paper's proposed 1650 BC date, a discrepancy he argues undercuts the airburst chronology specifically. Aren Maeir has noted that the burn pattern and destruction phenomena resemble other well-documented conflict-driven destructions rather than anything demanding an exotic mechanism. Geologists Jaret and Harris, reviewing the original mineralogical and geochemical claims directly, concluded in a 2022 peer-reviewed response that the quartz grains presented did not show convincing evidence of the kind of hypervelocity shock an impact would require, and that the melt and geochemistry claims had not been uniquely tied to a source outside the Earth.

Why Scientific Reports Retracted the Paper

The retraction did not happen quickly, and it did not happen quietly. After the 2022 image correction and the same year's Jaret and Harris critique, the specific comparison at the centre of the paper's title, that Tall el-Hammam's destruction matched the scale of the Tunguska event, came under direct challenge in 2025. Physicists Mark Boslough (himself cited as a source in the original paper) and Amy Bruno published a detailed reassessment showing that the airburst paper's Tunguska-based estimates of temperature, wind speed, and blast effects were substantially overstated, because they propagated older, since-corrected figures for the Tunguska event itself rather than the updated modelling the field now uses.

On 24 April 2025, Scientific Reports issued a formal retraction, stating that the editors were "no longer confident" in the paper's conclusions and that the claimed airburst destruction mechanism was not sufficiently supported by the underlying data, citing both the Jaret and Harris mineralogical critique and the Boslough and Bruno reassessment of the Tunguska comparison directly. The response from the paper's authorship split sharply: 11 of the 21 original authors, including corresponding author George Howard, publicly disagreed with the decision, with Howard calling it "a profoundly disappointing and frankly disgusting turn of events" and co-author Allen West alleging that "a small but vocal group of scientists has actively sought to stifle discussion," adding that the team intended to publish the underlying evidence again elsewhere. Nine co-authors made no public statement, and one, Ted Bunch, had died before the retraction was issued.

What the retraction does not do is address the Sodom identification. Scientific Reports is a general science journal assessing a specific physical claim, a cosmic airburst, against physical evidence; it made no finding on the separate, older, textually and archaeologically argued question of whether Tall el-Hammam is the city Genesis describes. Conflating the two, treating the retracted airburst paper as if it discredited the Sodom proposal, or treating the Sodom debate as if it validated the airburst paper, misreads what each claim actually rested on.

Current Consensus

The airburst hypothesis is not accepted by planetary scientists or archaeologists as an explanation for Tall el-Hammam's destruction; the peer-reviewed critique that led to retraction found its central mineralogical and comparative evidence unsupported, and Scientific Reports's own editors reached the same conclusion. What destroyed the city most probably falls into the same category as many other Bronze and Iron Age Levantine destruction layers, fire, plausibly connected to conflict, though no single peer-reviewed study has since established the precise cause with the same level of confidence the original paper claimed for its own account.

The Sodom identification remains a genuinely open, minority position. It is held by the site's own excavation team and by some evangelical scholars persuaded by its geographical argument, and rejected or treated as unresolved by most archaeologists and by other biblical scholars who prioritise the text's internal chronology, some of whom favour the older southern Dead Sea candidates instead. No consensus location for Sodom exists on this site's evidentiary framework or in the wider field; the honest position is that biblical Sodom's location, if it corresponds to any specific excavated site at all, has not been established.

Considered together, the episode is a documented example of the mechanism science relies on to correct itself: a striking claim published, media coverage disproportionate to the evidence's actual weight, image concerns raised almost immediately, then two rounds of peer-reviewed critique addressing the underlying data directly, and a formal retraction roughly three and a half years after publication once the journal's editors judged the critiques decisive. The Tunguska event sits at the centre of that correction in an unusual way: the very comparison the original paper used to make its case, that Tall el-Hammam's destruction matched Tunguska's, was the comparison Boslough and Bruno's analysis of Tunguska's own physics ultimately undid.

Why This Mystery Endures

Part of the pull here is structural, not evidential: a claim that a Genesis narrative might be literally, physically true, verified by peer-reviewed science, is a more shareable story than either "archaeologists remain divided" or "a paper's data did not hold up," and the 2021 coverage reflected that asymmetry, reaching a vastly larger audience than the quieter 2022 correction or the 2025 retraction did. The same asymmetry shapes the Durupınar site's recurring claims to be Noah's Ark: a dramatic, scripture-confirming identification travels further than the specialist literature that later qualifies or rejects it, and few readers who saw the original headline ever see the correction.

The underlying instinct, that a documented natural catastrophe might sit behind an ancient story of divine judgement, is not unique to Sodom. Genesis pairs the Sodom narrative with an even more widely studied case of the same structure: the flood story in Genesis 6–9, whose connections to older Mesopotamian flood traditions scholars have traced with far more documentary confidence than anything proposed for Tall el-Hammam. Both narratives describe a wicked population destroyed by an overwhelming force from outside human control, and both have attracted the same pattern of search: proponents looking for a physical site or artefact that would convert scripture into confirmed history, met by specialists arguing the search mistakes the genre, a moral and theological narrative, for a police report. Atlantis and El Dorado show the same instinct operating on classical and colonial-era legends instead of biblical ones, each pursued by generations of searchers convinced that a story this vivid had to have left something behind to find.

Tall el-Hammam's case adds a distinctive, more contemporary wrinkle: the correction happened in public, on the record, with named authors on both sides of the disagreement, rather than settling quietly the way most scientific disputes do. That transparency is arguably the story's most useful legacy, a documented case study in exactly how a peer-reviewed claim gets tested, challenged, and withdrawn when the evidence does not hold, sitting alongside this site's other disputed historical events as a reminder that "published in a peer-reviewed journal" and "settled" are not the same claim, and that the gap between them is where responsible scepticism, not dismissal, belongs. The Tanis fossil site makes the instructive counterpoint within the same cluster: another excavation team's dramatic impact-related claim that drew scientific scrutiny, but one whose foundational paper has withstood independent examination rather than being retracted.
