Interestingly, the same article has a hyperlink to an article that casts doubt on the Shroud of Turin. In my opinion, that story is slanted against the Shroud. It concludes that since the Shroud is not exactly the same style as another shroud found from the same time, that the Shroud of Turin is not true.
Also, a subsequent and far more thorough analysis of the Shroud, which the hyperlink failed to mention, concluded that the Shroud did date from the time of Jesus.
Lastly, the claim of the main story to be able to pinpoint an earthquake of 2,000 years ago to an exact Friday day and time is highly questionable.
They weren't pinpointing the exact date of the earthquake, only the year. They then deduced the crucifixion date from the date of Passover for that year.
