From: Thermal remote sensing reveals communication between volcanoes of the Klyuchevskoy Volcanic Group

Time-series of the time-averaged lava discharge rate (TADR; logarithmic scale) for (a) Klyuchevskoy, (b) Bezymianny, and (c) Tolbachik. Single satellite measurements (dots) are interpolated and smoothed (line) to provide continuous data. The horizontal dashed lines represent the threshold of 0.25 m3 s−1 used for automatized detection of eruptions (see “Methods” section). The start and end of each eruptive period (labelled on the top of each plot) are marked by the vertical dashed lines. The error for every single datapoint is ± 50%. The time series is generated using MATLAB software (www.mathworks.com).
