2021 Luxian earthquake
The 2021 Luxian earthquake was a damaging seismic event occurring in the early hours of September 16 at 04:33 China Standard Time. The surface wave magnitude (Ms) 6.0 or moment magnitude (Mw) 5.4 earthquake struck at a shallow depth of 7.5 km and severe shaking in an area of 4,000 square kilometers was assigned a maximum intensity of VIII on the China seismic intensity scale. Three people were killed and 146 injured when the earthquake struck Lu County, Luzhou, Sichuan Province. At least 36,800 buildings were affected, 7,800 of them seriously damaged or completely destroyed, causing about a quarter of a billion dollars worth of damage.
2015 Illapel earthquake
The 2015 Illapel earthquake occurred 46 km (29 mi) offshore from Illapel (Coquimbo region, Chile) on September 16 at 19:54:32 Chile Standard Time (22:54:32 UTC), with a moment magnitude of 8.3-8.4. The initial quake lasted between three and five minutes; it was followed by several aftershocks greater than magnitude six and two that exceeded 7.0 moment magnitude. The Chilean government reported 15 deaths, 6 missing and thousands of people affected. In Buenos Aires, Argentina, a man died from a stroke while he was evacuating a building.
Xi'an Metro opened
The Xi'an Metro, also known as the Xi'an Rail Transit, is a rapid transit system in the city of Xi'an and the neighbouring city of Xianyang, in Shaanxi province, China. The system has 9 lines in operation. Line 2 opened to the public on September 16, 2011. Line 2 runs north-south and passes under such historic sites as the Bell Tower and the Xi'an City Wall. It is 26.6 km (16.5 mi) long with 23.5 km (14.6 mi) lying underground, approximately 20 metres (65 ft 7 in) below the surface. It is estimated to have cost 17.9 billion yuan (US$2.24 billion). The route stretches from the Beikezhan to Weiqunan with 20 stops.
1978 Tabas earthquake
The 1978 Tabas earthquake occurred on September 16 at 19:05:55 local time in central Iran. The shock measured 7.4 on the moment magnitude scale and had a maximum Mercalli intensity of IX+ (Violent). The death toll was in the range of 15,000-25,000, with severe damage occurring in the town of Tabas. Eighty percent of the human deaths occurred in Tabas, but a total of 85 villages were also affected. This seismic force was felt in Tehran, about 610 kilometers (380 mi) away. About 55-85 km (34-53 mi) of ground deformation was observed, with about 1.7 meters (5 ft 7 in) of maximum slip. Only one significant M5 aftershock occurred.
Amsterdam Airport Schiphol opened
Amsterdam Airport Schiphol, known informally as Schiphol Airport is the main international airport of the Netherlands. It is located 9 kilometres (5.6 mi) southwest of Amsterdam, in the municipality of Haarlemmermeer in the province of North Holland. It is the world's third busiest airport by international passenger traffic in 2021. With almost 72 million passengers in 2019, it is the third-busiest airport in Europe in terms of passenger volume and the busiest in Europe in terms of aircraft movements. With an annual cargo tonnage of 1.74 million, it is the 4th busiest in Europe.
