Gee, I was just posting about #subsidence the other day...! Different places have different reasons for it to occur, but the worst is happening in Texas -- and #BigOilAndGas extraction is part of the problem there!

Big US cities are sinking. This map shows where the problem is the worst.

Excerpt: "How does groundwater extraction cause subsidence?

"Generally, according to a statement from Lamont-Doherty, it happens as water is withdrawn from aquifers made up of fine-grained sediments; unless the aquifer is replenished, the pore spaces formerly occupied by water can eventually collapse, leading to compaction below, and sinkage at the surface.

"In Texas, the problem is exacerbated by pumping of oil and gas, the study says."

Big US cities are sinking. This map shows where the problem is the worst.

The cities include not just those on the coasts, where sea level rise is a concern, but many in the interior.

@maggiejk It's happening in Florida as well... #subsidence is the culprit in both situations.

About 3 dozen high-rise buildings in South #Florida are sinking, a study finds

December 19, 2024

SUNNY ISLES BEACH, Fla. — "Almost three dozen high-rise condos and luxury hotels along the beach in South Florida are sinking or settling in unexpected ways, in some cases because of nearby construction, according to a new study.

"The 35 buildings surveyed along an almost 12-mile stretch from #MiamiBeach to #SunnyIslesBeach have sunk or settled by 0.8 to 3.1 inches. About half of the buildings are less than a decade old, according to scientists at the University of Miami Rosenstiel School of Marine, Atmospheric, and Earth Science. The study was published Friday.

" 'The discovery of the extent of subsidence hotspots along the South Florida coastline was unexpected,' Farzaneh Aziz Zanjani, the lead author, said in a statement. 'The study underscores the need for ongoing monitoring and a deeper understanding of the long-term implications for these structures.' "
