Elastic Interaction Between Mauna Loa and Kīlauea ~ Nature

8:21 PM · Nov 21, 2022

The relationship between our two most predominant volcanoes, Kilauea and Maunaloa, is quite complex as activity on one volcano has historically shown effect on the other. An inverse-correlation, or negative correlation, has been suggested between the two, that when one is more active the other volcano is less. This relationship is complicated by periods where both volcanoes erupt, but a new study was able to look past the historical record alone by using GPS monitoring to gather deformation data on both volcanoes. " The results revealed anticorrelated ground deformation behaviour of the main calderas of Mauna Loa and Kīlauea, meaning that the opposite response is seen in the ground deformation of one volcano with respect to the other. At the same time, Kīlauea exhibits a more complex pattern, with an additional component, which appears not to be correlated with the dynamics of Mauna Loa." Full write-up, by Monika Przeor (et al):
