NOAA Tsunami Debris Modeling:
Model Results: A majority of computer simulated low windage particles are dispersed across a wide area north and east of the Hawaiian Islands. The crosshatched portion in the center of the graphic does not represent a mass; rather, it shows the area where a higher number of low windage particles may be located.
High windage items, such as foam pieces and plastics, first reached the Pacific Northwest coast during the winter of 2011-2012 and Hawaii in the summer of 2012.
NOAA expects widely scattered tsunami debris to continue washing up along Pacific shorelines intermittently over the coming years, mixed in with non-tsunami marine debris.
