My current research on temporal patterns has led to trying to find seasonal patterns inside laminated sediments. The focus for now is on pollen. The amount of pollen and type of pollen deposited in the sediments varies throughout the year with the greatest amount and variation ocurring during the spring.
In 2016, some colleagues published an article where they were able to distinguish fall from spring deposition in Dead Sea sediments based on the pollen they found in the sediments (see the image below). This was proof of the concept that we could determine the time of year this earthquake occurred by examining the thin layer of sediment atop the Jerusalem Quake seismite (and right after the Jerusalem Quake)..
Unfortunately, determining with confidence whether the Jerusalem Quake struck during the spring is not so simple as taking one sample and examining it’s pollen. The deformation style of the seismites change laterally and sometimes later earthquakes leave overprints of deformation on already buried seismites. This means that multiple samples have to be taken and examined at multiple locations to form a sound scientific conclusion. This is why I am trying to find modest funding ($10,000 – $25,000) to do this work. We need a good statistical sample.
Once funded, I will do this research with Dr. Suzanne Leroy who was the second author in the 2016 article.
