Description

We estimated energies of shallow tremors detected by Yamashita et al. (2015) and Yamashita et al. (2021), and moments of shallow very low frequency earthquakes (VLFEs) detected by Asano et al. (2015) and those temporally correlated with shallow tremors detected by Yamashita et al. (2015) and Yamashita et al. (2021) in Hyuga-nada. We also evaluated scaled energies of shallow slow earthquakes in Hyuga-nada by the ratio of energy rate of tremors to moment rate of accompanying VLFEs.

The method of estimation of energies of tremors and moments of VLFEs is written in Baba et al. (2024  https://doi.org/10.1093/gji/ggae039). The content of each column is written in the first line of each file. The time is written in JST (UTC+9).
