	abstract = {During the 2018 Kilauea eruption, over half the erupted lava was deposited on the seafloor. Lava flows crossing the shoreline generated sounds that were recorded by a network of hydrophones. We show that short-duration, broadband signals associated with lava-water interactions occurred throughout the eruption but increased in number when the Ahalanui ocean entry initiated on July 11. These terminated in early August coincident with the eruption{\textquoteright}s end. We compare hydroacoustic data with transmission loss models and eruption photographs to show that coastal explosive activity was poorly recorded by the hydrophone network. Similarly, strong hydroacoustic signals did not correlate with observed activity. These results suggest that acoustic signals were generated by lava flowing up to 100 s of meters offshore. Offshore lava flows can be hazardous to boaters, but hydrophones provide a means by which these hazards can be detected.},

	abstract = {Hundreds of earthquakes were recorded during a nine-month ocean bottom seismometer deployment surrounding Lo{\textquoteright}ihi submarine volcano, Hawai{\textquoteright}i. The 12-station ocean bottom seismometer network widened the aperture of earthquake detection around the Big Island, allowing better constraints on the location of seismicity offshore Hawai{\textquoteright}i. Although this deployment occurred during a time of volcanic quiescence for Lo{\textquoteright}ihi, it establishes an important basis for background seismicity of the volcano. Offshore seismicity during this study was dominated by events located in the mantle fault zone at depths of 25{\textendash}40 km. These events reflect rupture on preexisting faults in the lower lithosphere caused by stresses induced by volcano loading and flexure of the Pacific Plate (Pritchard et al., 2007, https://doi.org/10.1111/j.1365-246X.2006.03169.x; Wolfe et al., 2004, https://doi.org/10.1029/2003GC000618). Tomography was performed using double-difference seismic tomography and showed shallow velocities to be slower than the regional velocity model (HG50; Klein, 1981, https://pubs.geoscienceworld.org/ssa/bssa/article/71/5/1503/118231/A-linear-gradient-crustal-model-for-south-Hawaii). A broad, low-velocity anomaly was observed from 20{\textendash}40-km depth, and is suggestive of the central plume conduit that supplies magma to Lo{\textquoteright}ihi and the active volcanoes of the Big Island. A localized high-velocity body is observed 4{\textendash}6-km depth beneath Lo{\textquoteright}ihi{\textquoteright}s summit, extending 10 km to the north and south. Following Lo{\textquoteright}ihi{\textquoteright}s active rift zones and crossing the summit, this high-velocity body is characteristic of intrusive material. Two low-velocity anomalies are observed below the oceanic crust, interpreted as melt accumulation beneath Lo{\textquoteright}ihi and magmatic underplating beneath Hawai{\textquoteright}i Island.},
