"Immense volcanic eruption" may have led to death of thousands in medieval England

Archaeologists for the Museum of London recently discovered 175 mass graves dating to around 1250, 100 years before the Black Plague. What killed over 10,000 people in England may have been an immense volcanic eruption.

Once the dates of the remains were determined, researchers ruled out the plague and began looking through period documents for answers. What they found was astonishing: a tremendous famine caused by the eruption of a powerful volcano as far away as South America or Indonesia.
