Positioning and monitoring system for marine component in recovery equipment of significant metals from seawater by using adsorbent was designed and assembled to avoid unexpected accidents. This system which was set on float part of the marine component obtains the position data by means of GPS satellites and send them to Takasaki and Mutsu establishments through satellite communication. As characteristic test for 20 days in the real sea, 256 data were obtained every 2 hours. The wrong data was eight and the positioning accuracy was 200.7m. To improve these characteristics, two new functions were added to the present firmware. These are to raise positioning resolutions in longitude and latitude from 0.001 to 0.00001 degree and to average remaining three data of positioning after maximum and minimum data were removed from continuous five times positioning. The improved system shows no wrong datum, average positioning of 6.74m. This performance is enough to prevent marine equipment from its drifting accident.

We estimated the strain released by the 2016 Kumamoto earthquakes in the co- and post-seismic periods and the strain rate in the inter-seismic period using GPS data. Moreover, based on the active fault data, we estimated geological strain rate. From the results, we found that the shear strain as much as 7.10310 strain was released by the M7.3 earthquake and the strain released within the first about 2.5 months following the main shock was estimated to be one order of magnitude smaller than that of the co-seismic period. Furthermore, the recurrence interval was estimated to be 3100 years by comparing geological strain rate and co-seismic strain released by the main shock. These results were good agreement with the recurrence interval evaluated from the active fault data.
