Fig. 11

Maximum amplitude of low-frequency earthquakes (LFEs) and very low frequency earthquakes (VLFEs). a Red circles show the maximum amplitude of LFEs as a function of association with VLFEs at IGK. Blue triangles denote the maximum amplitude of ordinary earthquakes within the frequency range 2.00–4.00 Hz as a function of the frequency range of 0.02–0.05 Hz. The hypocenters of the ordinary earthquakes are distributed within 23.3°–23.7°N, 123.3°–124.7°E at depths of <40 km (Fig. 1a). Horizontal and vertical lines denote the averaged noise level in the frequency ranges of 2.00–4.00 and 0.02–0.05 Hz at IGK, respectively. b Same as a but at ZMM
