A Telegraph article makes an interesting claim, in a discussion about the Shroud of Turin:
However a new study claims than an earthquake in Jerusalem in 33AD may have not only created the image but may also have skewed the dating results. The Italian team believes the powerful magnitude 8.2 earthquake would have been strong enough to release neutron particles from crushed rock.
And, USA Today reports something very similar:
...where Italian researchers suggest that an 8.2-magnitude earthquake that rocked Jerusalem in 33AD both formed the image and distorted the results of radiocarbon dating...
Ignoring the question of the age of the Shroud of Turin, the specificity of the magnitude 8.2 earthquake makes me ask - are there extant records of such an earthquake, or is the journal suggesting that there was an earthquake, and had it been magnitude 8.2, you have seen the effects in this shroud?
Obviously, the Biblical resurrection account mentions the earthquake, but is there any other corroboration?
