Glen Ivory Three

The Glen Ivory Three was a series of abnormal natural disasters that occurred in Glen Ivory in 1987.

Earthquake
On the 18th of April at 9:07 pm, a 7.1 magnitude earthquake shook the town of Glen Ivory. The earthquake caused a large underground mining tunnel to collapse, destroying seven buildings and leaving a deep trench across the town.

Flood
On the 27th of April, the Glen Ivory area received 180 mm of rain in under an hour. This caused the Dawson River to overflow and flood large parts of the town. Two homes were swept off their foundations, and three others collapsed due to severe water damage.

Sinkhole
On the 30th of April at 12:34 pm, a large sinkhole measuring almost 50 metres across opened up to the East of Kentley Street, causing nearby buildings to move by as much as 12 cm.

Affect on Population
By the 25th of April, Glen Ivory lost 75% of its population after the earthquake. The population decreased from 997 to 249 across just a week.

After the flood and sinkhole struck, many of the residents abandoned the town in fear that it was abandoned. Within one year, the town lost 80% of its population. The population decreased from 249 to 37.

Aftermath
By 1993, Gertrude Webnidder, her husband and two sons were the last residents of Glen Ivory. After her husband died in 1997 and her sons moved out in 1998, Gertrude Webnidder became the last resident of Glen Ivory.
