Data Center Description
The International Tsunami Expedition has finished a two week survey of the southern coast of Madagascar. The research team, consisted of Dr. D.Abbott, Lamont Doherty Earth Observatory of Columbia University, USA, Dr. E.Bryant, University of Wollongong, Australia, Dr. V.Gusiakov, Novosibirsk Tsunami Laboratory, Russia, Dr. W.Masse, Los Alamos National Lab, USA. The team was accompanied by two representatives of the University of Antananarivo, Andriamiranta Raveloson and Hoby Raza. The team obtained field data from large chevrons detected earlier this year using Google Earth imagery. The main purpose of this field trip was to measure the vertical and horizontal extension of the chevrons, to study their genesis and morphological features, and to obtain marine shell in order to determine their age. Another important goal of the expedition was to verify whether or not the chevrons discovered on satellite images represent mega-tsunami deposits and if so, to confirm the inferred run-ups derived from the imagery.
