We report on the very-low-frequency earthquakes occurring in the transition zone of the subducting plate interface along the Nankai subduction zone in southwest Japan. Seismic waves generated by very-low-frequency earthquakes with seismic moment magnitudes of 3.1 to 3.5 predominantly show a long period of about 20 seconds. The seismicity of very-low-frequency earthquakes accompanies and migrates with the activity of deep low-frequency tremors and slow slip events. The coincidence of these three phenomena improves the detection and characterization of slow earthquakes, which are thought to increase the stress on updip megathrust earthquake rupture zones. 相似文献

To determine the viability of hot water emasculation for Acacia auriculiformis, spikes composed of about 100 flowers were soaked in hot water at varying temperatures (45–60°C) and for varying lengths
of time (5 s to 7 min) prior to anthesis. The rate of squashed polyads, each of which consisted of 16 pollen grains, and the
germinating rate on media, decreased with temperature and time. A mating test suggested that the rates of adhering polyads
per stigma and germinating polyads per stigma were lower in the self-pollination of soaked spikes than in that of normal spikes.
On the other hand, the number of matured pods was not significantly different in the mating between the spikes receiving the
soaking treatment (♀) and the spikes receiving no treatment (♂) compared with the mating between normal spikes. Although further
research is needed to determine the optimal treatment conditions, these results suggest that soaking spikes into hot water,
especially at 50°C for 45 s, 54°C for 15 s, and 56°C for 10 s, is an effective emasculation technique. 相似文献
