Comparison of time series of daily (a) cc, (b) dv/v, (c–e) amplitude root mean square (RMS), f peak ground velocity (PGV), and g earthquake numbers in the Kilauea area. The dark and light colors in a and b represent the estimated dv/v and the corresponding errors in different frequency bands (red: 0.3–0.6 Hz, orange: 0.6–0.9 Hz, and blue: 0.9–2.0 Hz). The amplitude RMS of daily seismic records is calculated in c 0.3–2.0 Hz, d 0.1–0.3 Hz and e 0.01–0.1 Hz, respectively. The dark and light color curves in c–g indicate the results for the Station DEVL and Station STCD and the other stations. Vertical dashed lines mark the occurrence time of the earthquakes with M\(\ge 3.5\) (Fig. 1 and Additional file 1: Table S1). Green line marks the beginning time of the eruption
