Schematic showing magma storage beneath Yellowstone caldera. Nested calderas resulting from the Huckleberry Ridge Tuff, Mesa Falls Tuff, and Lava Creek Tuff caldera forming eruptions are shown as solid black, green, and orange lines, respectively.
Ninfa L. Bennington, Ph.D.
I am a volcano seismologist at the Hawaiian Volcano Observatory. Broadly, I am interested in developing new seismic methods as well as applying more standard seismic techniques to clarify magma storage and transport at active volcanic systems. Part of this work centers on developing real time forecasting tools for identifying when a volcano is entering into or moving out of a period unrest.

Unlike permanent seismic stations, which are placed farther apart and cover the entire Island of Hawai‘i, the temporary seismic nodes will be tightly grouped in order to more densely record earthquake signals across the region surrounding Pāhala.
