Researchers from the University of Hawai'i at Mānoa Department of Earth Sciences assessed an unprecedented 120 years of data from Kīlauea Volcano on Hawai'i Island, uncovering, for the first time, century-spanning patterns of deformation and stress changes. They had a particular focus on the transformative 1975 magnitude 7.7 Kalapana earthquake, which also resulted in a 20-foot high tsunami. Their study was published recently in the Journal of Geophysical Research: Solid Earth.
