The 1987 Edgecumbe earthquake measured 6.5 on the moment magnitude scale and struck the Bay of Plenty region of New Zealand on 2 March. The shock was centred on the town of Edgecumbe and occurred just after 1:42 pm. at a shallow depth of approximately 8 km. It was one of the most damaging New Zealand's North Island has experienced in recent decades, with approximately 50% of the houses damaged. There was extensive damage to a local milk factory, with large storage tanks toppled. Kawerau was another nearby town that suffered damage and Whakatane was also badly shaken. An 80-tonne New Zealand Railways DC class locomotive was thrown onto its side.

A crack 7 kilometres (4.3 mi) long opened in the Rangitaiki Plains near Edgecumbe. It is now known as the 'Edgecumbe Fault'. At one point, the land close to the fault dropped 2 metres (6.6 ft). Railway tracks were twisted and bent, and a diesel-electric locomotive toppled over.

The epicentre was approximately 2.24 kilometres (1.39 mi) south-south-east of the town of Matata, or 15 kilometres (9.3 mi) north-north-west of Edgecumbe. The intense ground shaking led to a large number of ground surface failures, including sand boils, ridge-top shatters and debris avalanches on steeper slopes.
