Snow plow swallowed by sinkhole in New Jersey.

A snowplow was swallowed by a sinkhole in a road in Lopatcong, New Jersey, at about 7.30 am local time on Tuesday 17 February 2015. The driver of the plow is reported to have been injured in the incident, but to have been able to escape from the hole unaided, though specialist equipment was needed to remove the plow. The hole is not thought to have presented any danger to local residents, though people living close to the incident were recommended to stay at home and not to take cars out of their drives.

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.
On this occasion the incident appears to have been caused by a burst water main beneath the road. A number of residents in the area reported losing water supplies the night before the incident, and it is likely that water escaping from a fractured pipeline eroded sediments away beneath the road, causing it to collapse beneath the weight of the snowplow.
