Indonesian Cave Reveals Nearly 5,000 Years of Tsunamis, Eos Earth and Space Science News, 7 August 2017

Yale-NUS Professor of Science (Environmental Studies and Geophysics) Brian McAdoo gave his expert opinion on the geological record contained within an Indonesian coastal cave. Earthquake geologist Charlie Rubin and his colleagues found a natural record of tsunamis sweeping sand repeatedly into the cave over thousands of years. By radiocarbon dating the sandy layers, the researchers were able to achieve what’s often thought of as a holy grail in tsunami science: a reconstruction of when previous tsunamis occurred thousands of years in the past. Professor McAdoo noted that the study represents the first time that cave data have been used to measure tsunami recurrence intervals.
