The Long-Lost Tale of an 18th-Century Tsunami, as Told by Trees
Oxytropidoceras posted a topic in Fossil News
The Long-Lost Tale of an 18th-Century Tsunami, as Told by Trees Local evidence of the cataclysm has literally washed away over the years. But Oregon’s Douglas firs may have recorded clues deep in their tree rings. Max G. Levy, Wired Magazine, September 29, 2021 the paper is: Dziak, R. P., Black, B. A., Wei, Y., and Merle, S. G., 2021, Assessing local impacts of the 1700 CE Cascadia earthquake and tsunami using tree-ring growth histories: a case study in South Beach, Oregon, USA, Nat. Hazards Earth Syst. Sci., 21, 1971-1982. Related paper is; Patton, J. R., Goldfinger, C., Morey, A. E., Romsos, C., Black, B., Djadjadihardja, Y., and Udrekh: Seismoturbidite record as preserved at core sites at the Cascadia and Sumatra-Andaman subduction zones, Nat. Hazards Earth Syst. Sci., 13, 833-867. Yours, Paul H.-
