Abstract
On 2 March 1987 the 86 m high Matahina earth dam in the Eastern Bay of Plenty region of New Zealand was shaken by a nearby magnitude 6.3 earthquake. The dam response was recorded by five strong motion accelerometers and a maximum crest level acceleration of 0.42 g was measured. The crest level rockfill settled about 100 mm and moved downstream 250 mm during the earthquake. No major leakage has resulted from the earthquake. The results of the damage investigations are described. A condition probably requiring remedial work has been identified on the left abutment.

The Observed Seismic Behavior of the Matahina Dam
On 2 March 1987 the 86 m high Matahina earth dam in the Eastern Bay of Plenty region of New Zealand was shaken by a nearby magnitude 6.3 earthquake. The dam response was recorded by five strong motion accelerometers and a maximum crest level acceleration of 0.42 g was measured. The crest level rockfill settled about 100 mm and moved downstream 250 mm during the earthquake. No major leakage has resulted from the earthquake. The results of the damage investigations are described. A condition probably requiring remedial work has been identified on the left abutment.
