For our storyboard, we want to focus on how development and change on the Bund has affected the geology of Shanghai starting from the late 19th century to the present.
Location: underneath shanghai (geology)
- Shanghai is built on soft sediments
- It has developed a lot in the past 50 years
- The bund was the center of activity and the old buildings have been converted into hotels, high-end restaurants, etc.
- Lujiazui is now the financial center and many new skyscrapers have been built in the past 30 years
- The first metro line was opened in 1995 and now 25 years later there are 16
- The population of shanghai has doubled in the past 30 years and it’s also an extremely popular tourist site
- This rapid development and increase in population has affected the geology of shanghai
- More groundwater is being used, leading to subsidence (the city is sinking about 7mm per year)
- Subsidence is also increased in the areas where there are the most tall buildings
- Metro tunnels being dug deeper have led to some tunnel collapses as well as the buildings above
- Satellites can capture even small changes in the elevation of ground in shanghai and the government is working to offset subsidence
- The city has soared economically with all the growth but subsidence and sea level rise has lead to its literal sinking
