Mariana dam disaster
The Mariana dam disaster, also known as the Bento Rodrigues or Samarco dam disaster, occurred when the Fundão tailings dam at the Germano iron ore mine of the Samarco Mariana Mining Complex near Mariana, Minas Gerais, Brazil, suffered a catastrophic failure, resulting in flooding that devastated the downstream villages of Bento Rodrigues and Paracatu de Baixo (40 km (25 mi) from Bento Rodrigues), killing 19 people. The extent of the damage caused by the tailings dam collapse is the largest ever recorded with pollutants spread along 668 kilometres (415 mi) of watercourses. The failure of the dam released 43.7 million cubic metres of mine tailings into the Doce River.
Tropical Storm Thelma floods Ormoc
Tropical Storm Thelma, was one of the deadliest tropical cyclones in Philippine history, killing at least 5,081 people. Forming out of a tropical disturbance on November 1, 1991, several hundred kilometers north-northeast of Palau, the depression that would become Thelma tracked generally westward. After turning southwestward in response to a cold front, the system intensified into a tropical storm on November 4 as it approached the Philippines. Near the city of Ormoc, a Philippine National Oil Company rain gauge measured 580.5 mm (22.85 in) of precipitation, the highest in relation to the storm. Of this, approximately 500 mm (20 in) fell during a three-hour span around noon local time on November 5.
Astoria-Megler Bridge construction started
The Astoria-Megler Bridge is a steel cantilever through truss bridge in the Pacific Northwest region of the United States that spans the lower Columbia River. It carries a section of U.S. Route 101 from Astoria, Oregon, to Point Ellice near Megler, Washington. Opened in 1966, it is the longest continuous truss bridge in North America. The bridge is 14 miles (23 km) from the mouth of the river at the Pacific Ocean. The bridge is 4.067 miles (6.55 km) in length, and replaced the final segment of U.S. Route 101 to be completed between Olympia, Washington, and Los Angeles, California.
James Clerk Maxwell died
James Clerk Maxwell was a Scottish mathematician and scientist responsible for the classical theory of electromagnetic radiation, which was the first theory to describe electricity, magnetism and light as different manifestations of the same phenomenon. Maxwell's equations for electromagnetism have been called the "second great unification in physics" where the first one had been realised by Isaac Newton.
