Fresh oil flowed out from thispoint.

Thick oil lump around the severed bow section

State of oil washed ashore
The spilt oil was spread by the tide and wind from the east, adhering to debris as itfloated, with much of it stranded ashore onto the mouth of Tabaru River.
It is interpreted that natural dispersion of the oil was promoted by rough weather and big
surf caused by the typhoon, also rising water level of Hishida and Tabaru River by rainfall
on the previous days formed a natural barrier, led majority of the oil to drift ashore on
relatively narrow area than originally expected.

No thick oil layer remaining on the sea surface,but a thin oil film, formed by oil oozing from the oil adhered to the “oil snare”, floats on
the water, and the outer reaches thereof are dispersed by wind and waves.
