    <p>We carried out a temporary seismic observation using 4 ocean bottom seismographs in and around the Aira caldera to obtain the precise hypocenter distribution, especially in the Wakamiko caldera. During the observation period from July to September 2020, we observed two short-time seismic swarms that occurred inside the Wakamiko caldera and revealed the precise distribution of these hypocenters and the focal mechanism solution. In contrast to our results, the JMA unified hypocenters of the two swarms are widely distributed in the western region outside the Wakamiko caldera. This difference in the hypocenter distributions insists that the seismic observation in the sea area around the Wakamiko caldera is required to reveal the precise seismic activity in the caldera.</p>

    The tectonic stress field was investigated in and around the aftershock area of the Hokkaido Eastern Iburi earthquake (MJMA = 6.7) occurred on 6 September 2018. We deployed 26 temporary seismic stations in the aftershock area for approximately 2 months and located 1785 aftershocks precisely. Among these aftershocks, 894 focal mechanism solutions were determined using the first-motion polarity of P wave from the temporary observation and the permanent seismic networks of Hokkaido University, Japan Meteorological Agency (JMA), and High Sensitivity Seismograph Network Japan (Hi-net). We found that (1) the reverse faulting and the strike-slip faulting are dominant in the aftershock area, (2) the average trend of P- and T-axes is 78° ± 33° and 352° ± 51°, respectively, and (3) the average plunge of P- and T-axes is 25° ± 16° and 44° ± 20°, respectively: the P-axis is close to be horizontal and the T-axis is more vertical than the average of the P-axes. We applied a stress inversion method to the focal mechanism solutions to estimate a stress field in the aftershock area. As a result, we found that the reverse fault type stress field is dominant in the aftershock area. An axis of the maximum principal stress (σ1) has the trend of 72° ± 7° and the dipping eastward of 19° ± 4° and an axis of the intermediate principal stress (σ2) has the trend of 131° ± 73° and the dipping southward of 10° ± 9°, indicating that both of σ1- and σ2-axes are close to be horizontal. An axis of the minimum principal stress (σ3) has the dipping westward of 67° ± 6° that is close to be vertical. The results strongly suggest that the reverse-fault-type stress field is predominant as an average over the aftershock area which is in the western boundary of the Hidaka Collision Zone. The average of the stress ratio R = (σ1 − σ2)/(σ1 − σ3) is 0.61 ± 0.13 in the whole aftershock area. Although not statistically significant, we suggest that R decreases systematically as the depth is getting deep, which is modeled by a quadratic polynomial of depth.[Figure not available: see fulltext.]

    The remarkable eruption on Kuchierabujima, which occurred on May 29, 2015, had the potential to disrupt land seismic observation if the volcanic activities had expanded. Since relatively deep-volcano-tectonic (DVT) earthquakes under the volcano may have extended into the sea region around the island, we deployed four ocean bottom seismometers (OBSs) on the seafloor at distances at approximately 6.5 km from the crater. During the OBS observation period from July 3 to October 9, 2015, 303 volcanic earthquakes were detected. The daily numbers and the temporal amplitude changes indicate that seismic activities declined in the middle of August. However, only nine of the events were DVT earthquakes, and we were unable to identify any clear differences between the hypocenter distribution characteristics of the DVT events discussed in previous studies and those of our observations. However, since the temporal tendency of daily earthquake numbers derived from our OBS data resembled that compiled by the Japan Meteorological Agency using real-time land data, when eruption expansions occur on a small-scale remote island such as Kuchierabujima, OBS observations can provide a useful backup to efforts aimed at grasping the seismicity.
