Martinez, who grew up in earthquake prone Chile, is no stranger to earthquakes But when he and his colleagues walked out of the building to avoid, they were surprised to find that there were many people standing in the central green space of Lujiazui, the largest open space in the area, and more white-collar people were rushing out of the surrounding office buildings, some were panic, some were relaxed, some were nervous, and their expressions were different Martinez said that although there was little earthquake in Shanghai, everyone was calm and united in the face of emergencies Although Lujiazui is more than 1600 kilometers away from the epicenter, most of the people who work here feel a slight shake and are evacuated Lujiazui makes a false alarm Lujiazui Central green space is located in the middle of Lujiazui area, covering an area of 100000 square meters Around it, there are large domestic and foreign enterprises such as Bank of China (601988 market, stock bar), HSBC, Huaneng, etc In Lujiazui, the area with the highest population density in Shanghai, the green space plays an important role Lujiazui Financial District, with an area of only 2.1 square kilometers, has an average population density of 10687 people / square kilometers, second only to Tokyo, the most crowded city in the world There are nearly 400 Chinese and foreign financial institutions working here, and tens of thousands of office workers come to work here from all sides of the city every day High prices give birth to high buildings There are more than 30 class A office buildings here, and about 15 will be rebuilt in the future Among them, there are some world-famous super tall buildings, such as the 420 meter high Jinmao Tower and the 482 meter high global financial center (under construction) And the world's tallest building, planned to be built in 2013, up to 530 meters "Shanghai center" Lujiazui is a signboard of Shanghai's opening up, which has long been a landmark of Shanghai The public green space in this area is mainly Lujiazui Central green space, Riverside Park and Pearl Park Xiao Luo, who works in the office building next to the central green space, recalled: "when I looked down from the upstairs, I saw that the green space was full of people." Xiao Luo, who works in the HSBC building, was also shocked that day When he felt the shaking, the broadcast of HSBC building rang out soon, calling on the people in the building to leave the office temporarily 40-50 employees in Xiaoluo's Office responded quickly and left their seats one after another to walk to Lujiazui green space Fortunately, the earthquake in Shanghai was not strong People gathered in the green space regarded evacuation as a "gap" About 90 minutes later, Xiao Luo's colleagues returned to the office one after another, and their work returned to normal But in Lujiazui, a place with dense buildings, people have to think about how to deal with sudden disasters such as earthquakes The evacuation caused Xiao Luo's department to temporarily stop trading "It's hard to say the loss, because it depends on the market changes in this period of time." After Xiao Luo finished speaking, he hung up the phone in a hurry and went back to work It took about 10 minutes for the earthquake wave to reach Shanghai
