Earthquake
Dunedin was hit by an earthquake at about 7.49pm on 9 April 1974.[6] Another earthquake struck the city a few seconds later, which was longer and stronger.[6] It was magnitude 4.9 and measured VIII (severe) on the Modified Mercalli intensity scale,[7][8] and had an epicentre that was offshore, about 5 kilometres south of the suburb of St Clair. This one caused power outages and chimneys to fall down. There were several aftershocks with a magnitude 3.7 following this.[6]
The Earthquake and War Damage Commission received about 3,000 damage claims,[6] and paid out about $3.5 million (in 2024 terms), which was mainly from falling chimneys and masonry.[7]
