. When the ship was about 1000 nautical miles off the coast of Newfoundland, a major North Atlantic storm arose, buffetting the ship with 25 feet (7.6 m) waves and 44-mile -per-hour winds. In response, the ship sent out a distress signal and kept heading for shore. However, when the ship was 700 nautical miles (1,296.4 km) off the coast of Nova Scotia, an explosion occurred on board, causing the ship to break into two and begin sinking. As the ship sank, a fire broke out on its stern section, causing the oil on board to catch fire. All 27 crew members, 15 Greeks and 12 Hondurans, are presumed to have died during the incident. Because of hazardous weather conditions, the Canadian Coast Guard

 could not immediately reach the spill and much of the oil burned up before the coast guard reached the ship.

Environmental effects

In the immediate aftermath of the ship's sinking, the oil spill covered an area of 3 miles (4.8 km) x 10 miles (16.1 km). However, no oil reached shore - in part because of the oil's rapid combustion from the initial explosion and in part because currents carried the spill across the Atlantic, in the direction of England, giving the oil a significant amount of time to dissipate. Because of this, no clean-up operation was mounted.
