In 2002, the sinking of which tanker caused a major environmental disaster off the coast of Spain?

The Prestige oil spill occurred off the coast of Galicia, Spain, caused by the sinking of the 26 year old structurally deficient oil tanker MV Prestige in November 2002, carrying 77,000 tonnes of heavy fuel oil. During a storm, it burst a tank on November 13, and sank on November 19, 2002, about 130 miles (210 km) from the coast of Galicia. It is estimated that it spilled 17.8 million US gallons (420,000 bbl) (or a mass of 60,000 metric tonnes) of heavy fuel oil.

The spill polluted thousands of kilometers of coastline and more than one thousand beaches on the Spanish, French and Portuguese coast, as well as causing great harm to the local fishing industry. The spill is the largest environmental disaster in the history of both Spain and Portugal. The amount of oil spilled was more than the Exxon Valdez incident and the toxicity considered higher, because of the higher water temperatures.
