Melbourne (Antarctica) 2026-04-08T15:21:00 https://antarcticdatacenter.cnr.it/geonetwork/srv/api/records/fb76df45-1654-46c0-b827-b4252769fe0f Continuous seismic monitoring data from Mt. Melbourne volcano (Victoria Land) are recorded for volcanic risk mitigation. The dataset includes raw continuous waveforms and processed products like Root Mean Squared (RMS) amplitude time series and seismic event counts. Seismic signals cover volcanic seismic signals, ice-quakes, and microseism background signals. Processed data is available for direct download via the provided dashboard links, whereas raw continuous seismic data can be obtained upon request to the point of contact/PIs. This resource was developed to establish a permanent monitoring system for volcanic risk mitigation at Mt. Melbourne and Mt. Rittmann while providing a continuous stream of high-quality data to advance multidisciplinary scientific research in volcanology, geophysics, and glaciology.

Spectrograms use Welch’s method with 81.92 s windows on 10-minute segments. - Amplitude Estimation: For continuous signals (microseism, tremor), root mean squared (RMS) amplitudes are calculated. RMS values are computed on the vertical component, typically filtered in the 0.1–40 Hz band
