Scientists have confirmed the largest ever hailstone occurred in Argentina two years ago.
The hailstone was about the size of a football, scientists report.
The hailstorm occurred over the city of Villa Carlos Paz, Córdoba Province, Argentina.
The biggest stone in the storm measured up to 23.6cm in diameter.
However, the stone was not preserved and cannot be officially verified as a record-breaker.
The hail in the storm was so large that scientists suggest a new category to describe stones bigger than 15 centimetres – ‘gargantuan’ hail.
Researchers investigating the storm interviewed witnesses, visited sites where the damage occurred, collected photo data and analysed radar observations.
