Dr. Joseph D. Ortiz, a professor in the College of Arts and Sciences’ Department of Geology at Â鶹ÊÓƵ, was part of an international team of researchers that co-authored an article about a deadly tsunami that occurred about 1,000 years ago in Tanzania. The study suggests that the tsunami risk in East Africa could be higher than previously thought.
Ortiz processed and interpreted the grain size data using a multivariate statistical analysis method, demonstrating the deposit was composed of sediment from both terrestrial and marine origin, which supports the tsunami interpretation.
