Abstract :
Measurements of microseisms in Auckland, New Zealand, are compared with ocean wave data taken on the west coast of New Zealand, about 150 km southwest of Auckland. There is strong correlation at most times. Exceptions are when the Auckland area is subject to strong winds from the easterly quarter. Microseism activity in Auckland in the 0.05-1-Hz band appears to be entirely due to ocean waves
