HVO intern increases understanding of deformation at Kīlauea

InSAR image of Kīlauea's summit area, showing subsidence of both rift zones and the northern part of the caldera, with uplift near Halema`uma`u and Keakanako`i craters. Sarah's work showed that deformation in the summit area has occurred at a more or less constant rate since 2003, except for the uplift around Keanakano`i, which began about May 2004.
