利用在海底获得的实时和连续时间序列数据进行地震和微海啸观测的科学成果开始出现在文献中。JAMSTEC在日本水域总共开发了8个有线观测站中的3个。安装的观测站都在运作，以协助地震研究，减轻未来潜在危险的灾害，这些危险发生在日本岛屿周围的板块边界。沿着地震活动监测的目的，已经清楚的是，有潜在的和科学意义的结果，从这样的观察。我们总结了最新的科学成果，从监测数据产生的有线观测站，然后，以证明这种水下地震和海啸站的优势。到目前为止，可以指出三个主要领域是电缆观测的有意义的科学产品：（1）近海地震活动的精细测绘，（2）深源地震引起的微海啸压力波动的建模，以及（3）使用海啸模拟来约束震源参数，例如近海事件的震源深度。这些都是从观测数据中得出的有趣的科学结果，也可以很容易地用于关于板块边界变形过程的地震研究和关于海啸预警系统的研究，作为未来减灾方法的一部分。很明显，新部署的监测系统至少部分地揭示了有意义的现象，这些现象由于缺乏近海观测而无法克服。为了更深刻地认识与近海地震活动有关的地球物理过程，必须充分考虑近海地震监测的技术和理论发展。
Scientific results started appearing in the literature using realtime and continuous time series of data obtained on the seafloor for seismic and micro-tsunamic observations. JAMSTEC has developed three out of a total of eight cabled observatories in the Japanese water. The installed observatories are all operating to aid earthquake studies for disaster mitigation at the future potential hazards, which take place at plate boundaries surrounding the Japanese islands. Along with earthquake activity monitoring purposes, it has become clear that there are potentially and scientifically meaningful outcome from such observations. We summarize the latest scientific results from monitored data produced by our cabled observatories and, then, to demonstrate advantages of such underwater seismic and tsunamic stations. Until now, three main areas could be pointed out as meaningful scientific products from cabled observations: (1) fine mapping of offshore seismicity, (2) modeling of micro-tsunamic pressure fluctuations caused by deep earthquakes, and (3) constraining earthquake source parameters such as source depths of offshore events using tsunami simulation. They are all interesting scientific results from the observational data could also readily be exploited for earthquake studies on deformation processes at the plate boundaries and on early tsunami warning system as a part of future disaster mitigation methodologies. It is obvious that newly deployed monitoring systems have revealed, at least partially, meaningful phenomena, which have been invincible due to lack of observations in the offshore. Technical and theoretical developments for offshore earthquake monitoring must be well considered for profound perception of geophysical processes associated with offshore seismic activities.
