Before I start this, let me inform you that many and perhaps most New Testament scholars view Matthew’s description of an earthquake at the crucifixion as fictitious. They have good reasons for this.
But I let the sediments be my guide.
Further, I suspect that the history of this earthquake account may be more complicated in a way that we have not yet considered.
New Testament Scholarship appears to be in fairly good agreement on three important points surrounding the date of the crucifixion
1. It happened between 26 and 36 AD
2. It happened during spring around the time of Passover or Easter (14 or 15 Nisan in the Jewish Calender)
3. Although the exact year is unknown, two years (30 and 33 AD) are most commonly cited as the most likely year of the crucifixion.
Armed with these facts, I can design my tests to examine the sediments. There is no way I can date the exact day this seismite was formed using technology currently available (sorry Discovery “News” Channel). However, I do hope to refine the year estimate and I want to see if I can determine the time of year that the seismite was formed (e.g Winter, Spring, Summer or Fall).
