We conducted a detailed investigation of an earthquake cluster distributed from the lower crust to the upper crust beneath Hakodate, Hokkaido, which included both low-frequency earthquakes (LFEs) and regular earthquakes.

Long-term activity change in Very low-frequency earthquakes in the south Ryukyu Trench
2023Very low-frequency earthquakes (VLFEs) occurred regularly along the south Ryukyu Trench. The activity was concentrated at the slab depth of 10-20 km along the trench axis. The VLFEs occurred every two to three months for a few days in a seismic swarm.

AbstractDeep tectonic tremors detected in many subduction zones worldwide are often accompanied by very low frequency (VLF) signals, detectable by broadband seismometers but usually hidden in large ambient noise. By stacking broadband seismograms relative to tremor hypocentral times, we can recover the VLF signals. The stacked signals are then inverted

Precursors signatures of few major earthquakes in Italy using very low frequency signal of 45.9 kHz
Acta Geophysica, 2019On May 20 and May 29, 2012, earthquakes of magnitude MW 6.1 and 5.8, respectively, struck Emilia-Romagna of Italy. We present the results obtained from the US Navy VLF Transmitter’s NSY signal of 45.9 kHz transmitted from Niscemi, in the province of Sicily, Italy, and received at the Kiel Longwave Monitor, Germany, for 2012.

The characteristics of shallow low‐frequency earthquakes (LFEs) are related to stress changes on the shallow plate boundary, which are important for understanding the megathrust earthquake cycle.

Very low frequency (VLF) seismic signals observed in southwestern Japan are evidently radiated from shear slips on the upper surface of the subducting Philippine Sea Plate. We used grid moment tensor inversion and centroid moment tensor inversion to calculate 242 moment tensor solutions with moment magnitudes between 3.1 and 3.8 from continuous ...
