Due to the influence of heavy rain brought by Tropical Storm "Agatha", a huge pit with a depth of about 100 meters appeared in the urban area of Guatemala City, the capital of Guatemala on May 30, which shocked the world. In strict geological terms, a sinkhole refers to a huge deep hole formed due to the constant erosion of solid bedrock by water and the subsequent collapse of the earth's surface. There are many places in the United States that have a high probability of sinkholes appearing.
