A sinkhole is a natural depression caused by the removal of underground soil by water. Usually, it happens when the substrate is
formed by limestone, carbonate rock, salt beds or any other rock that is
easily eroded by water streams. The process could be slow, but
sometimes the land just cracks open without notice. In this case, it
happened suddenly, swallowing an entire house. The cause: Massive
underground water torrents created by tropical storm Agatha.
Sinkholes' size ranges from low terrain depressions to hundred of meters. Unlike the similar sinkhole that killed two teens in 2007, there
seems to be no victims. At least one local newspaper is reporting
one person dead, but the authorities have not confirmed it. Some
neighbors claim that a whole three-story building and a house fell into
the hole.
