Coast guards said the latest oil spill would cause only minor damage since diesel oil evaporates easily. When the collision occurred, winds were not strong, blowing at 4-6 m per second. Waves were also moderate at 0.5 m. Coast guards believe the tanker will not sink. The collision occurred in distant waters and will no great impact on fish farming.
Stolen from the Naver article.
Last night an oil tanker collided with a fishing boat 18 kilometers south of one of Yeosu's outlying islands, and caused the release of roughly 50 kiloliters (13,208 gallons) of oil. Yonhap has the story via Naver, and I'm sure English-language updates will come later in the day.
The last major accident off Yeosu happened in December, when two ships collided and 14 sailors went missing. That came about two weeks after the largest oil spill in Korean history.
If the 50 kiloliter, 13,208 gallon number is accurate, that is mercifully smaller than the December spill off Taean county, which released 2.7 million gallons.
