When magma moves into the rift zone of a Hawaiian volcano, there is understandably a lot of excitement and apprehension. How far will the magma go? Will it erupt? But even long after the activity stops — regardless of whether it erupts — the subsurface magma continues to have a noticeable impact on the landscape.

Data from 115 seismic nodes deployed in late June across the East Rift Zone of the Big Island’s Kīlauea volcano, fortuitously before significant unrest began, will be used to image the location and volume of magma within the region at a level of detail not previously possible.
