Vertical-component seismic waveforms and spectrograms from AVO station ILSW for the May 2016, June 2019, and June 2023 avalanches on Iliamna Volcano. Waveforms are high-pass filtered at 100 s. All axis limits are identical. Modified from Figure 4 in Toney et al. (2021). Toney, L., Fee, D., Allstadt, K. E., Haney, M. M., & Matoza, R. S. (2021).
