Algiers Metro opened
The Algiers Metro is a rapid transit system that serves Algiers, the capital of Algeria. Originally designed in the 1970s, it opened in 2011 after decades of delays due to financial difficulties and security issues. The Algiers Metro was the second metro system to open in Africa, after the Cairo Metro. The first phase of Line 1, "Haï el Badr"-"Tafourah-Central Post Office", which had a length of 9.2 kilometres (5.7 mi) and comprised 10 stations, opened for public service on 1 November 2011. A 4-kilometre (2.5 mi) extension from "Haï el Badr" to "El Harrach Centre" opened for commercial service on 4 July 2015 after test runs in June.
Jacques Piccard died
Jacques Piccard was a Swiss oceanographer and engineer, known for having developed underwater submarines for studying ocean currents. In the Challenger Deep, he and Lt. Don Walsh of the United States Navy were the first people to explore the deepest known part of the world's ocean, and the deepest known location on the surface of Earth's crust, the Mariana Trench, located in the western North Pacific Ocean.
Milan Metro opened
The Milan Metro is the rapid transit system serving Milan, Italy, operated by Azienda Trasporti Milanesi. The network consists of 5 lines, identified by different numbers and colours, with a total network length of 104.1 kilometres (64.7 mi), and a total of 113 stations, mostly underground. It has a daily ridership of about 1.4 million on weekdays. The Milan Metro is the largest system in Italy for length, number of stations and ridership; and the seventh longest in the European Union.
Springhill mining disaster
The 1956 explosion occurred on November 1, and killed 39 coal miners, but 88 others underground were rescued because of improved equipment. Prior to the blast, a mine train was hauling a load of fine coal dust up to the surface of the Number 4 colliery for removal from the pithead, and encountered a heavy flow of ventilation air being forced down the shaft by surface fans. The flow of air disturbed the contents of the ascending train cars and spread fine (and highly flammable) dust throughout the air of the shafts of No. 4. Before the train reached the surface, several cars broke loose and ran back down the slope of No. 4, derailing along the way and hitting a power line, causing it to arc and igniting the coal dust at the 5,500-foot (1,700 m) level (below surface).
White House construction completed
The White House is the official residence and workplace of the president of the United States. It is located at 1600 Pennsylvania Avenue NW in Washington, D.C., and has been the residence of every U.S. president since John Adams in 1800 when the national capital was moved from Philadelphia to Washington, D.C. The term "White House" is often used as metonymy for the president and his advisers. The residence was designed by Irish-born architect James Hoban in the neoclassical style. Hoban modelled the building on Leinster House in Dublin, a building which today houses the Oireachtas, the Irish legislature. Construction took place between 1792 and 1800, using Aquia Creek sandstone painted white. The mansion was reconstructed after it was set on fire by British forces in the 1814 burning of Washington.
1755 Lisbon earthquake
The 1755 Lisbon earthquake, also known as the Great Lisbon earthquake, impacted Portugal, the Iberian Peninsula, and Northwest Africa. In combination with subsequent fires and a tsunami, the earthquake almost completely destroyed Lisbon and adjoining areas. Seismologists estimate the Lisbon earthquake had a magnitude of 7.7 or greater on the moment magnitude scale, with its epicenter in the Atlantic Ocean about 200 km (120 mi) west-southwest of Cape St. Vincent, a cape in Algarve region, and about 290 km (180 mi) southwest of Lisbon. Estimates place the death toll in Lisbon around 12,000, making it one of the largest earthquakes in history.
