Shanghai World Financial Center construction started

The Shanghai World Financial Center is a supertall skyscraper located in the Pudong district of Shanghai. It is a mixed-use skyscraper, consisting of offices, hotels, conference rooms, observation decks, and ground-floor shopping malls. On 14 September 2007, the skyscraper was topped out at 492 meters (1,614.2 ft), making it the 2nd tallest building in the world on completion (the tallest at the time being Taipei 101), the tallest building in the world by roof height only, and the tallest in China.

1966
Astoria-Megler Bridge was completed

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.

1963
Kane Creek potash mine explosion

The Moab or Kane Creek potash mine is located along the right (northwest) bank of the Colorado River, about 20 miles (30 km) west of Moab, Utah, at the south end of State Route 279 and the Union Pacific Railroad. The plant opened in 1963 as a conventional underground mine. Later that year, an explosion trapped 25 miners, of whom only seven were able to survive, by building a barricade to trap fresh air.

1883
1883 eruption of Krakatoa peaked

The 1883 eruption of Krakatoa in the Sunda Strait occurred from 20 May until 21 October 1883, peaking in the late morning hours of 27 August when over 70% of the island of Krakatoa and its surrounding archipelago were destroyed as it collapsed into a caldera. The eruption was one of the deadliest and most destructive volcanic events in recorded history. The explosion was heard 3,110 kilometres (1,930 mi) away in Perth, Western Australia, and Rodrigues near Mauritius, 4,800 kilometres (3,000 mi) away. The acoustic pressure wave circled the globe more than three times. At least 36,417 deaths are attributed to the eruption and the tsunamis it created.

1859
Drake Well drill reached maximum depth

The Drake Well is a 69.5-foot-deep (21.2 m) oil well in Cherrytree Township, Venango County in the U.S. state of Pennsylvania, the success of which sparked the first oil boom in the United States. The well is the centerpiece of the Drake Well Museum located 3 miles (5 km) south of Titusville. The Drake Well is often referred to as the first commercial oil well, although that title is also claimed for wells in Azerbaijan, Ontario, West Virginia, Myanmar, Persia, Arabia, Sichuan China and Poland, among others.
