66-foot-deep sinkhole opens up on New Zealand farm
A nearly 66-foot-deep sinkhole has opened up on a farm near Rotorua, New Zealand after several days of heavy rainfall. Locally known as "Tomo", the sinkhole, which volcanologists said could have been forming for up to 100 years, is almost 600 feet long. It is the ninth sinkhole to form on the farm in recent years.
