Here are some links. This story made a splash in May 2012.
This is Jefferson Williams' site, article, and appearance in a thread:

Here is Steve Austin, creationist geologist, on the same subject:

The published article by Jefferson Williams does have two co-authors, and it does seem to be worth taking seriously. The conclusions are moderately stated:
Unfortunately, there does seem to be some degree of plausibility to the suggestion that the counting of the varves has been fitted to the chronology of Pilate, as discerned in this quote from the article:
1. There is no reference to existing standard methods in assigning a margin of error here. Instead the author works out what the margin of error should be, based on a simple ratio, based on a single comparison, and that involving two teams working on the same problems. It seems like it would be possible for geologists to have a better consensus about this subject, whether they already have one or will develop one, with better foundations.
2. There still is no strong reason to accept 31 AD as the center on which the margin of error should be calculated. For example, this other person came up with 33 AD as their count, presumably by counting 64 varves from the 31 BC earthquake recorded by Josephus. What this illustrates is that we still haven't eliminated the inaccuracy that can come from the way of counting varves. If 33 AD were the center, which seems just as legitimate on the face of it, then the 5-year margin of error would exclude 26-27 AD while including 37-38 AD, which means that we haven't included the full range of plausible dates when using the exact count and tight range that Williams does.
3. In order to represent that possible inaccuracy, one simple suggestion is to round off to the nearest decade point (20, 30, 40, etc.) and add 5 years to the margin of error. This would avoid giving the impression of having more accuracy than we can actually have. This would give us 30 AD +/- 10 years instead.
I wonder whether Williams' work has been reviewed with a response by other geologists.

Here are bloggers responding to it:I am the primary author of the research article discussed in this article. We DID NOT determine the date of the crucifixion. This article grossly mischaracterizes our research. We dated an earthquake in Judea to have occurred between 26 and 36 AD based purely on what we saw in the sediments. I created a site to explain this research to the general public. It is http://www.crucifixionquake.info.
I've been told this isn't the first time Discovery News has pulled a stunt like this. Apparently, a large media corporation that purports to explain science to the general public doesn't mind trashing reputations and damaging research as long as it generates clicks and revenue for their site. Who would have thought that a large corporation whose CEO received ~40 million dollars in compensation last year would do such a thing ? (2010 (http://www.forbes.com/lists/2012/12/ceo ... _D9HF.html).
Please visit my site and see if you agree with me. Our article was written by scientists; not believers. Scientists who don't presuppose the outcome with faulty front loaded conclusions.
When this kind of thing happens, this type of research is ceded to Creationists who believe in a 6000 year old earth, a global Noachian flood 5000 years ago, and fail to recognize the brilliance of Charles Darwin in explaining how the fossil record is explained by Natural Selection.

The published article by Jefferson Williams does have two co-authors, and it does seem to be worth taking seriously. The conclusions are moderately stated:
The second option from Williams seems to match what Kris is asking about. Of course we have no very strong reason to arbitrate between explanations (2) and (3).This leaves three possibilities for the cause of the 26–36 AD earthquake observed in the Ein Gedi section:(1) the earthquake described in the Gospel of Matthew occurred more or less as reported; (2) the earthquake described in the Gospel of Mathewwas in effect ‘borrowed’ from an earthquake that occurred sometime before or after the crucifixion, but during the reign of Pontius Pilate;(3) the earthquake described in the Gospel of Matthew is allegorical fiction and the 26–36 AD seismite was caused by an earthquake that is not reported in the currently extant historical record.
Unfortunately, there does seem to be some degree of plausibility to the suggestion that the counting of the varves has been fitted to the chronology of Pilate, as discerned in this quote from the article:
The critical passage about the varve counting is here:This places the above-postulated 31 AD earthquake within the 26–36 AD window (31±5 years) when Pontius Pilate was Procurator of Judea and the earthquake of the crucifixion is historically constrained.
However, as seen from the fact that the exact center of 31 AD is used, no uncertainty due to the uncertainty of varve counting has entered the final estimate. All the counted varves have been used in the 62 year difference between 31 BC and 32 AD, including all 36 varves that had a quality rating of 1. Instead a margin of error has been assigned based on other considerations:A varve quality index is defined below.
1. Discontinuous ambiguous clastic layer.
2. Clearly identifiable clastic layer but thickness estimate is not very accurate.
3. Well-preserved varve with good accurate estimate of thickness.
Every counted varve was assigned an index value of 1, 2,or 3. For the purpose of this study, where the goal is accurate chronological dating, a varve quality index value of 1 indicates that the varve is somewhat suspect and a varve quality index of 2 or higher indicates that the varve count is regarded as fairly certain. In the 62 years counted from 31 BC to 31 AD, 36 (58%) had a varve quality rating of 1 and 26 (42%) had a varve quality rating of 2 or higher.
I'm not a geologist, but a few things about this concern me:One way to determine the accuracy of this estimateis to compare the varve-counting accuracy of this studywith that of Migowski (2001), who counted varves in thesame core. Since both investigations independently cameup with similar dates for the early first-century earth-quake (31 AD vs.
∼
33 AD in Migowski (2001)), this isconsidered to be a valid comparison. Between two well-defined ‘anchor’ earthquakes of 31 BC and 1293 AD,Migowski (2001) counted 1324 varves. Of these, 94 yearswere masked by earthquake deformation. Inasmuch asMigowski (2001) used varve counts in the masked intervalsto match her varve-counted year to historically documented earthquakes, the number of masked years in the 1324-year interval represents a combination of deformed layersand adjustments in the varve count to account for errorsin varve counting; 94 years out of 1324 years amountsto 7.1%. Assuming a worst case scenario that the entiremasked varve count is due to varve-counting errors, 7.1%of the 62-year interval between 31 BC and 31 AD amountsto 4.4 years. Rounding up, this means that for any givenearthquake between 31 BC and 31 AD, the dating pos-sesses an accuracy of at least
±
5 years. This places theabove-postulated 31 AD earthquake within the 26–36 ADwindow (31
±
5 years) when Pontius Pilate was Procurator ofJudeaandtheearthquakeofthecrucifixionishistoricallyconstrained.
