At the Northern Haster Tip of Amazon, Brazil, the huge chase is made on the edge of the giant chase that has suddenly opened in the ground. Large -scale sinkhole Put more than a thousand people at risk of losing their homes, motivating the state government to declare emergency.
Search Sinkhols has appeared in cities around the world in cities including America, Türkiye and Iran. They may appear suddenly, pose danger to life and homes.
What are the sinkhole really?
When the soil of water disappears, there is depression in the synchronous ground. This can naturally occur when the rain moves through rainfall, dissolve the underlying. But this can thus be the result of dripped underground water pipes, fossil fuels and fracting for mining activity.
The area is more likely to be in the region with Sinkhols “Carrst Terrain” – an area composed of solo drys such as limstones, salt beds, or gypsum – that can be dissolved by groundwater, said the professor of environmental science with Hong Yang, UK reading. Yang has recently published Research on reducing acute synchronous hazards from climate change,
“In the United States, about 20% of the land is susceptible, Florida, Texas, Alabama, Missouri, Kentki, Tennessi and Pennsylvania experience the most important damage,” he told DW. Other hot spots include UK, especially in Northern England regions such as Ripon and Yorkshire Dells, Lajio region of Italy, Yukatan Peninsula in Mexico, China, Iran and parts of Turkey.
What role does climate change play?
According to research, climate change is increasing the frequency of synchron by accelerating extreme weather events.
“Reduce dried water table, removing subtrenian support for the land.
He pointed to the Bradbacket, Konya Maidan, Turkish in Central Anatolia. It is a kare area where the growing drawwatman Sinkhole is now opening in the populated area.
Prior to the 2000s, researchers in the region used to register a synchron every few years, Fetullah Eric, a professor at the Konya Technical University, said, who is the head of the University’s Sinkhol Research Center. In 2024 alone, he documented 42.
The groundwater level in the Koni Basin has reduced at least 60 meters (197 ft) as compared to 1970.
“In some areas, close to the basin edges, groundwater cannot be found, although the wells more than 300 meters are drilled,” he said.
Climate is reducing the dry ground water level associated with change as rainwater is not re -doing sources. But because people still need access to water, they are pumped a lot of it, which, in turn, increases the risk of synchron. In populated areas, so this means that buildings are more unsafe to collapse.
“If you pull the water out rapidly from a juice box, in the sides,” Antonios E. Marslos said, Geology, Associate Professor of Environment, and Stability at Hoffastra University in the state of New York. “It is like pumping too much groundwater, so the support of underground underground weakens and the juice can fall like a box.”
Marsllos, who published Research on climate change effects on sinkhole structures,
Said that it is worse in big cities with air pollution where water becomes more acidic and breaks the rock rapidly.
Marcelos and his team saw the freeze-pile cycles in Long Island, New York around 80 years and found that temperature has weakened soil stability due to climate change and has a direct impact on synchronous structures.
Can we stop Sinkhole?
Yang said that experts rely on the discovery of technologies such as satellite remote sensing and ground-penetrating radar, so that they can detect micro-ground sub-group and underground Voids to spot Sinkhole before falling. Other detection methods include monitoring groundwater levels and conducting ground technical surveys before construction in the area.
If an empty zero is found to be underground, experts act like a dentist, Marselos said.
“This is exactly what we do – we check if there is a cavity, basically there is no more empty space below the ground that will not eventually have to keep the empty space.”
Depending on the discovery of local conditions as a makeup of rock and tectonic activity, the cavity can then be filled, for example, with cement, he said.
In the Konya Basin region of Turkey, where more than 80% of water is consumed by agriculture, Akir said that the most important factor is to regulate excessive ground water, so the soil has a natural stabilizer undernath. The farmers have now switched to more efficient error.
The region has tried several water transfer projects, discovering as a blue tunnel project, which takes water from the Goxu River to help fill the Konya Maidan.
Other prevention strategies include controlling drainage and fixing leaks and implementing strict building code, Yang said. “Engineering solutions can stabilize the ground by injecting the grout to fill the voids, compact loose soil, or to strengthen the land.”
