USGS Hawaiian Volcano Observatory broadband-seismic stations located at the summit of Kīlauea have been significantly upgraded over the past three years. During the upgrades, HVO field engineers (inset) complete the wiring connections of the solar power and telemetry systems at each site, which are about 10 m (33 ft) from the seismometer.
