The Croatian government has begun to repair the sinkholes in an agricultural area near the capital, which caused panic among the villagers, who watched the number and scale of sinkholes continue to expand.
On December 29 last year, a magnitude 6.4 earthquake occurred in central Croatia, killing 7 people. Less than a week later, these sinkholes showed dramatic phenomena in early January.
Tips on headlines around the world, including refer to For “Swiss Cheese”, about 100 cesspits appeared around the towns of Mecencani and Borojevici in the southeast of the capital Zagreb.
The largest tiankeng is nearly 30 meters (98 feet) in diameter.
The “good harvest” of tiankeng is unusual because earthquakes and other seismic events usually don’t cause them. However, in areas where groundwater has eroded the bedrock below and can no longer support the soil above, tiankeng does appear.
The chief engineer of the Croatian National Geological Survey, Stepan Terzic, said that although tiankeng is a normal phenomenon, it is unusual for a high concentration “in such a small place”, but the shock caused by the earthquake has accelerated the appearance of tiankeng. .
He told AFP: “Therefore, in a short period of time, many loopholes have appeared. Under normal circumstances, it will take decades or even longer to resolve these loopholes.”
Josip Stipčević, a seismologist at the Department of Geophysics, University of Zagreb, Tell All-Croatian News The earthquake experienced by the country was the result of the movement of tectonic plates below the surface. The large Eurasian plate collided with the smaller Adriatic plate (part of the larger African plate).
Since the beginning of the 20th century, Croatia has experienced 9 earthquakes of magnitude 6 or higher.
The repair work to fill the tiankeng began last week and is expected to last for a month and a half.
