From: Ground strains induced by the 2022 Hunga-Tonga volcanic eruption, observed by a 1500-m laser strainmeter at Kamioka, Japan

Fig. 6

Spectra of detided strain and atmospheric pressure fluctuations for a \({L}_{1}\), b \({L}_{2}\), and c \({L}_{3}\) (plotted with coherence). The higher coherences and similarity in the shapes of the strain and pressure spectra were commonly observed below a few mHz, which suggests a strong correlation between them, as expected from the waveforms shown in Fig. 4
