    Description: On August 30 1984, an earthquake swarm activity occurred at sea off the east coast of Izu Peninsula. An experimental observation of the acoustic wave of the swarm was carried out by the survey ship TENYO with a hydrophone at sea just above the focal area during the active period of the swarm. The hydrophone was hanged from the ship down to a deep water, to a few hundred meters above the seabottom. A large number of seismic events were recorded and their arrival times were measured precisely. The hypocenteres determined from the land observation data and additional hydrophone data were compared with the tentative hypocenters determined from only the land observation data by JMA (Japan Meteorological Agency). The comparison clearly pointed out that the hydrophone data had largely contributed to improve the accuracy of the determined hypocenters, especially in the accuracy of depth determinations. The most beneficial point of the hydrophone observation is its capability of real-time monitoring which allows evaluations of the activity of earthquake swarms on a real-time basis. The other significant advantage is its mobility which enables to keep the observation point within the area just close to the epicenters, even when they migrate considerably. These advantages seem to pave the way to establish a new method of real-time monitoring of earthquake swarms at sea.

    Description: Background Despite their importance in population health among children and adolescents, our understanding of how individual items mutually interact within and between pediatric health-related quality of life (HRQOL) and school social capital is limited. Methods We employed network analysis in a general population sample of 7759 children aged 9–15 years to explore the network structure of relations among pediatric HRQOL and school social capital items measured using validated scales. Furthermore, network centrality was examined to identify central items that had stronger and more direct connections with other items in the network than others. Network structure and overall strength of connectivity among items were compared between groups (by sex and age). Results Our analysis revealed that the item related to school/academic functioning and the item related to shared enjoyment among students had the highest strength centrality in the network of HRQOL and school social capital, respectively, underpinning their critical roles in pediatric HRQOL and school social capital. Additionally, the edge connecting “I trust my friends at school” and “trouble getting along with peers” had the strongest negative edge weight among ones connecting school social capital and pediatric HRQOL constructs. Network comparison test revealed stronger overall network connectivity in middle schoolers compared to elementary schoolers but no differences between male and female students. Conclusion The network approach elucidated the complex relationship of mutually influencing items within and between pediatric HRQOL and school social capital. Addressing central items may promote children’s perceived health and school social capital.
