对夏威夷岛熔岩的古地磁研究建立了以下结论：(1)岛上现在暴露的所有熔岩都不到100万年(更新世)。(2)目前中太平洋地区非偶极子场分量的缺失是一个相对持久的特征，至少持续了几十万年。(3)在过去的100万年中，主偶极子磁场发生了摆动，周期长达105年，振幅大于15°。(4)近100万年来主偶极场的平均方位比现在的旋转轴平移了5°。
Paleomagnetic studies of lavas from the island of Hawaii have established the following: (1) All lavas now exposed on the island are less than 1 million years old (Pleistocene). (2) The present absence of nondipole field components in the central Pacific area is a relatively permanent feature, having lasted at least several hundred thousand years. (3) During the last million years, the main dipole field has wobbled, with periods up to 105 years and with amplitudes greater than 15°. (4) The average orientation of the main dipole field during the last 1 million years was displaced 5° from the present rotation axis.
