During ROPOS Dive R1840, the broadband seismometer at the MJ03F junction box at the Central Caldera site, as well as the adjacent surroundings were inspected to see if the site was impacted by the April 24 eruption. The water was quite cloudy around the site. Ten pea gravel bags were placed around the broadband instrument to better couple it to the seafloor. Credit: NSF-OOI/UW/ISS; V15.
