A Pennsylvania Dadi Was found dead After falling last December A 30-foot dark synchron It was opened in a long abandoned coal mine.
Elizabeth PollardFrom Ekta Township, His cat was looking for pepper According to the officials when she fell. The 64 -year -old was remembered as a gardener, who preferred to roam in the neighborhood with his five -year -old granddaughter.
Pollard’s niece Tabita Pollard said, “His granddaughter was his world.” Pittsburgh tribune-review“Wherever she was, her granddaughter was with her.”
Sinkhole 20 percent land threatened in the United StatesAccording to the American GeoCINES Institute, but the possibility of a deadly encounter with one is thin.
But due to climate change, the number of sinkhols is increasing globally, causing excessive rainfall due to the extreme weather, causing the land to behave unexpectedly.
Now, researchers at Pennsylvania say they have a way to detect geological phenomena before they strike using underground fiber optic cables Run across the country for high-speed internet,
Before detecting synchhols, they appear by recording sound waves that bounce cables with a special tool, and then analyze them for warning signals.
The sound waves created by cars or construction can be distinguished from those created by rocks, which have clues about density and movement.
The device was capable of identifying a potentially risky space in the campus of Pen State University, although researchers said that the people there were not in any adjacent threat.
“We geologists often think of everyday traffic such as inputs such as noise in data. However, our research suggests that the so-called ‘waste noise’ is very useful,” explained in one by an associate professor Tiuan Zhu, an associate professor of geophysical in school, explained in one. statement,
Zhu stated that the device, known as “distributed acoustic sensing inquiries”, would be both more economical and effective than current methods. Currently it is a JioPhone that transforms speed into an electrical signal underground, and can sell up to a few thousand dollars.
It is not clear how the new tool will cost but it has already been deployed to help prevent disasters in Pittsburgh. It also records more data than JioPhone, the scientists said.
Pennsylvania is one of a handful of states where there is more likely to be synchronized. In 2020, more than 3,600 sinkhols were reported in Pennsylvania alone Wpsd local 6,
Hole where Pollard fell Is full of grout since then But this process may take months or years.
Sinkhole is more often in rock areas that can be dissolved by ground water. Both Pennsylvania and Florida are highly weak because they relax on limestone, which is filled with holes and easily dissolves.
Texas, Alabama, Missouri, Kentaki and Tennessy are also affected and have experienced the most important damage, Hong Yang, Hong Yang, an environmental science professor at the University of Reading, UK, Told dw.com.
This year, Sinkhole has also been Informed in Virginia And CaliforniaSwallowing cars and ripping the roadways. International level, a large -scale Sinkhol hit a road in Bangkok, Thailand, earlier this month, forced to withdraw The Associated Press.
Although there is no national tracking of synchron and related damage in the US, their cost is at least $ 300 million every year in the last 15 years, American geological survey,
The country’s largest, some 325 feet, in 1972 in Alabama. Known as “Goli Hole”, This did not harm people or property.
