夏威夷海底地质观测站（英语：Hawai'i Undersea Geo‐Observatory，简称HUGO）是一个位于夏威夷洛伊希海山（英语：Lo'ihi seamount）的海底观测站。一条电光电缆将HUGO接线盒连接到夏威夷大岛上的海岸站，从而实现了对海底火山的首次真实的实时监测。HUGO在1998年活跃了3个月，在高速水听器上收集几乎连续的真实的时间数据。在这段时间内探测到的信号包括当地地震和大地震，太平洋地震的T阶段，基拉韦厄海底侧翼的滑坡，以及当前基拉韦厄火山喷发的声音。这些数据并不表明在HUGO活跃期间发生了Lo'ihi喷发。HUGO水听器探测到的信号的多样性和质量证实了真实的时间观测台可以在海洋声学、地方和海洋地震以及海底喷发力学的研究中发挥宝贵的作用。
The Hawai'i Undersea Geo‐Observatory (HUGO) is an ocean bottom observatory located on the summit of Lo'ihi seamount, Hawai'i. An electro‐optical cable connects the HUGO junction box to a shore station on the Big Island of Hawaii, thereby enabling the first real‐time monitoring of a submarine volcano. HUGO was active for 3 months in 1998, collecting nearly continuous, real‐time data on a high‐rate hydrophone. Signals detected during that time include local as well as teleseismic earthquakes, T phases from Pacific‐wide earthquakes, landslides on the submarine flank of Kilauea, and eruption sounds from the current Kilauea eruption. The data do not indicate a Lo'ihi eruption during the time that HUGO was active. The variety and quality of signals detected by the HUGO hydrophone confirms that a real‐time observatory can serve a valuable role in studies of oceanic acoustics, local and teleseismic earthquakes, and submarine eruption mechanics.
