One person has died and another injured after a sinkhole opened up beneath a swimming pool in Israel on Thursday 21 July 2022. Both the victims were male, and were attending a company party at the villa where the pool was located, at Carmel Yosef, 40 km to the southeast of Tel Aviv, when the incident happened. Witnesses report that six people were in the pool when the hole opened, rapidly drawing in all the water in the pool, along with several floating toys and the two victims. Other bathers were able to avoid being drawn in by clinging on to the side of the pool. One of the men drawn into the hole was able to climb out with minor injuries, but the second, identified as Klil Kimhi, 32, from Tel Aviv, was found dead by rescue workers four hours later at the bottom of a fifteen metre pit.
Sinkholes are generally caused by water eroding soft limestone or unconsolidated deposits from beneath, causing a hole that works its way upwards and eventually opening spectacularly at the surface. Where there are unconsolidated deposits at the surface they can infill from the sides, apparently swallowing objects at the surface, including people, without trace. Potash, a potassium salt, is readily soluble and can be dissolved quickly if water gains access to deposits, leading to the rapid formation of sinkholes.
