Dating mega-tsunamis in Cape Verde

Tom recently went to Cape Verde together with Dr. Ricardo Ramalho to sample tsunami deposits of an ancient mega-tsunami. These deposits, first found by Ricardo and published in Science Advances, were created 73,000 years ago during a flank collapse of nearby Fogo Volcano that caused a tsunami wave of at least 170 meters height. At PKU we are now working on a new method to date tsunami deposits that were previously impossible to date using conventional methods such as cosmogenic dating.
