DescriptionBay of Plenty Earthquake, 1987 (16552659081).jpg
At 1.35 p.m. on 2 March 1987, a magnitude 5.2 earthquake struck the Bay of Plenty region, cutting power and sending many people outdoors. Minutes later a much stronger quake rocked the region. This main shock, at 1.42 p.m., had a magnitude of 6.3 and was centred north of Edgecumbe. Four aftershocks with magnitudes greater than 5 occurred in the next six hours, and smaller aftershocks were felt for weeks.
The Edgecumbe earthquake was the first since the 1968 Īnangahua quake to cause major damage. Although not of an exceptional magnitude, it was damaging because it was very shallow. No one was killed, but several dozen people suffered serious injuries.
The most spectacular effect of the Edgecumbe earthquake was the 7-kilometre-long rift that appeared across the Rangitāiki Plains – the Edgecumbe Fault. A fissure up to 3 metres wide and 3–4 metres deep opened up along much of the fault, although some sections were marked just by zones of cracks. The earthquake had been caused by movement along the fault; the land to the north-west had dropped by up to 2 metres. The region which sank downward is now more prone to flooding.
As these images from the Ministry of Civil Defence, Central Regional Office show, railway tracks were twisted and bent, and a diesel-electric locomotive toppled over. They come from a collection of photographic albums covering disasters, exercises, course photographs, publicity material, staff photographs, study trips, emergencies, and overseas visits.
