1. Overall Background Noise Statistics (I95 Violin Distribution Summary)
Shows the statistical density profile across all processed windows. Red markers highlight the statistical mean, blue lines represent data medians.
The I95 value defines the continuous ambient background noise level (Bodenunruhe), calculated after Groos and Ritter (2009) (DOI: 10.1111/j.1365-246X.2009.04343.x). It represents the exact interval width enclosing 95% of all recorded seismic amplitude samples within a zero-mean time series window.

Day-by-day temporal sequence variation for individual stations. Red dots signify high-noise day windows (06:00 to 18:00); Black dots correspond to local quiet night windows. The Red line shows the median value over the time series.
