基拉韦厄火山南翼在过去二十年中经历了两次大[震级（M）7. 2和M 6. 1]地震。1990年至1993年期间进行的全球定位系统测量显示，基拉韦厄中心南翼以每年约10厘米的速度向海移动。相比之下，火山的北方一侧和南翼的远端并没有发生明显的位移。这些观测结果可以解释为南翼下方低角度断层的滑动，以及基拉韦厄裂谷系统深处的扩张，两者的速度都至少为每年15厘米。
The south flank of Kilauea volcano has experienced two large [magnitude (M) 7.2 and M 6.1] earthquakes in the past two decades. Global Positioning System measurements conducted between 1990 and 1993 reveal seaward displacements of Kilauea's central south flank at rates of up to about 10 centimeters per year. In contrast, the northern side of the volcano and the distal ends of the south flank did not displace significantly. The observations can be explained by slip on a low-angle fault beneath the south flank combined with dilation deep within Kilauea's rift system, both at rates of at least 15 centimeters per year.
