French Agents Sink Greenpeace Ship Rainbow Warrior

In the 1980s, Greenpeace campaigned against French nuclear testing in the South Pacific, planning protests with its flagship vessel. On July 10, 1985, while the Rainbow Warrior was docked in Auckland Harbour, New Zealand, French DGSE agents attached two limpet mines to its hull. The resulting explosions sank the ship and killed photographer Fernando Pereira. Initially blamed on unknown saboteurs, the attack was quickly traced to France through investigations involving arrested agents. The incident caused an international scandal, strained France-New Zealand relations, and drew global attention to nuclear testing issues.

Live Aid Concerts Raise Funds for Ethiopia

The 1983-1985 famine in Ethiopia had already prompted the charity single 'Do They Know It's Christmas?' in late 1984. On July 13, 1985, organizers Bob Geldof and Midge Ure staged simultaneous benefit concerts at Wembley Stadium in London and JFK Stadium in Philadelphia. Over 75 acts performed across 16 hours, including Queen, U2, Madonna, and Paul McCartney, broadcast live via satellite to an estimated 1.5 to 1.9 billion viewers in more than 100 countries. Additional concerts occurred in other nations. The event raised over $100 million for famine relief and demonstrated the power of music and media for humanitarian causes.

Titanic Wreck Located in the Atlantic

After the RMS Titanic sank in 1912, numerous expeditions searched the North Atlantic without success due to the extreme depth and vast search area. In 1985, a joint U.S.-French team led by oceanographer Robert Ballard of Woods Hole Oceanographic Institution and Jean-Louis Michel of IFREMER used the unmanned submersible Argo equipped with sonar and cameras. After weeks of systematic searching, debris appeared on sonar screens early on September 1, followed by confirmation of a boiler identical to those on the ship. The main hull sections were located nearby at approximately 12,500 feet. The discovery provided the first images of the wreck in over seven decades.

Disaster 20th Century Latin America & Caribbean

Nevado del Ruiz Erupts, Burying Armero in Lahars

Nevado del Ruiz volcano in Colombia had shown increased activity for months, with warnings issued by scientists, yet local authorities and residents received mixed or delayed evacuation orders. On November 13, 1985, the volcano erupted explosively in the evening, melting glacial ice and generating fast-moving lahars of mud, rock, and water. These flows raced down river valleys at high speed toward populated areas. The town of Armero, home to about 28,700 people, was largely engulfed overnight. Approximately 23,000 residents perished, with thousands more injured or displaced in what became Colombia's deadliest volcanic disaster.

Reagan and Gorbachev Hold First Summit

After years without a U.S.-Soviet summit, President Ronald Reagan and Soviet General Secretary Mikhail Gorbachev met in Geneva, Switzerland, beginning November 19, 1985. The leaders held private talks at Villa Fleur d'Eau and other venues, discussing arms control, the Strategic Defense Initiative, and broader Cold War tensions. Although no major treaties emerged from the three-day meeting, the personal rapport established between Reagan and Gorbachev marked a shift from prior hostility. Both sides expressed cautious optimism about future dialogue and agreed to additional summits. The encounter helped thaw superpower relations during the final phase of the Cold War.
