Well, you could have looked that up before responding
Ampil:
"... caused significant flooding, inundating 31,600 hectares of crops and affecting 260,000 people. One person was killed in China and total economic losses reached ¥1.19 billion (US$175.2 million)"
13W: No significant impact
Rumbia:
"Rumbia killed a total of 22 people in East China and total economic losses were counted to be CN¥9.2 billion (US$1.34 billion).[114][115] Shouguang where 174.7 mm (6.88 in) of rain fell, was particularly hard-hit, with 10,000 homes destroyed and 13 people killed. The city is regarded as the nation's greatest producer of vegetables and agriculture suffered tremendous losses; 200,000 greenhouses sustained damage. Upstream on the Mi River rainfall reached 241.6 mm (9.51 in) and caused significant flooding. Water levels at three reservoirs rose dangerously high, prompting officials to release excess water to avoid collapse. The resulting increase downstream exacerbated the flooding in Shouguang.
Remember, we're just ones that hit
this year. In 2015, Chan-hom hit near Shanghai, but not the city proper.. 1,1 million people were evacuated from the coast (coast = GF3). Nearly 30k ships were called back to port and 600 flights cancelled. "
The storm produced high waves from Fujian to Jiangsu provinces, reaching five storeys high in Wenling, washing fish ashore and flooding the coast." In total, "
Overall, Chan-hom affected 3.9 million people in eastern China, causing about ¥9.8 billion (US$1.5 billion) in damage"
In 2005 Cat 2 Matsa hit a good distance from Shanghai, yet still "
Heavy rainfall in Shanghai flooded 84 city streets; in some locations insufficient water drainage left homes and apartments flooded, with a total of 20,000 houses reporting flooding. The flooding also closed the city subway system for a few hours. Strong winds downed 2,700 trees and 400 power lines in the city. The typhoon damaged a construction site in the city, leaving three injured and one person killed. Throughout the city an estimated 15,000 houses were destroyed. Additionally, four people were electrocuted as a result of the flooding. In Shanghai alone, damage totaled $1.33 billion (2005 CNY, $164.5 million 2005 USD); seven people died in the city."
The same year, Cat4 Khanun hit at pretty much the same location, but harder. More than 800k people had to be evacuated (remember, this wasn't a hit on Shanghai itself). Damages totaled to $849 million (2005 USD).
The previous year (2004), Typhoon Rananim hit pretty much the same location (not Shanghai proper). "
Wind gusts were recorded up to a local record of 211 km/h (131 mph). A total of 188 people were killed by the storm, mostly due to collapsed homes and landslides; roughly 1,800 were injured and over 18 million were affected by Rananim.[9] Economic losses in China amounted to about $2.2 billion (USD)"
I could keep going, but you get my point. Shanghai is
very much in the firing line of very powerful storms, and it's been lucky that many of the most powerful ones recently have hit off to one side or the other.
That's an interesting attitude to take towards building a critical facility in a flood plain on reclaimed land in Typhoon Alley.
The wave heights from the Touhoku tsunami reached 4 meters
in Chile and killed at least 12 people there. All the way across the Pacific. Colour me skeptical that a location immediately next to one of the most powerful subsea faulting zones in the world, built on low-lying reclaimed seafloor, is at little threat from tsunamis. Japan - a country famously proactive against natural disasters - vastly underestimated the potential. China is famous for downplaying the threats natural disasters can pose to its cities.
I would count being rated as the eighth riskiest city in the world for natural disasters "disrupting life".
Reclaimed land is riskier to flooding (whether from rain, surge, tsunamis, etc) and liquefaction in earthquakes. That's just the way it is. It has not been compacted over millennia.
On land that used to be ocean, and is currently barely above sea level.
