Silicon technology valley is at risk of being below sea level by 2100

The main reason is that sea levels are increasing and the city's grounds are severely subsiding.

The study's findings are published in the recent Science Advances magazine, a large area of ​​the San Francisco Bay area is slowly sinking while sea levels are increasing. Results were taken from observed satellite data InSAR in the period of 2007-2011.

San Francisco, USA, the "capital city" of Silicon Valley.

Some areas are sinking at 10mm / year, but more worrisome is that the sea level is increasing by 3mm / year and there is no sign of stopping.

According to Dailymail, the ground in the San Francisco Bay Area is in danger of subsidence due to the majority of the land here built on natural mudflats and burial sites still in process. dress.

Combining the two geological elements of San Francisco Bay and rising sea levels , the healthy land of the world's leading technology companies such as Apple or Google is in danger of soon becoming an underwater city in the future. hybrid

The main author of the study, Manoochehr Shirzaei, assistant professor at Arizona School of Earth and Space Research revealed:

"The ground is falling, the sea level rises again and the flood water is getting more and more inland. Most of the San Francisco Bay coastline is sinking below 2mm / year, but in some areas. In the area, we found the rate of subsidence up to 10mm / year or more ".

Previous research has made the forecast quite optimistic given that, only about 51km2 of land is at risk of flooding in 2100. However, based on the impacts of coastal subsidence, houses science has increased the size of affected land to at least 125km ² .

Even in the case of high tides and storm surges, the risk of flooded land can range from 130-430 km ² in 2100.

Places in the San Francisco Bay area are at risk of sinking below sea level by 2100.

Buildings at risk are mainly garbage dumps or San Francisco International Airport, which handles more than 200 thousand transports and about 56 million passengers a year. When seawater attacks the mainland, the airport's runway can be flooded and affect the ability to take and land.

However, Dr. Shirzaei also affirmed: "There are many estimates and models of sea level rise. But all are not enough because they do not take into account the change in the height of the soil."

Not all endangered areas are landfills. Areas with rivers and streams containing sludge into the Gulf are recording lower levels of groundwater. Groundwater depletion also causes land to be submerged below sea level.

The study by US scientists will be an important source of data to help local officials plan early emergency response to the situation of land subsidence and rising sea levels in the future. This will also be the top concern of many high-tech companies such as Apple or Google, Microsoft if companies want to maintain their existence in a place that is considered the technology capital of the world longer.
