Fig. 1

Plots of filament eruptions according to \(V_{\text{r}\_\max}\) (top left), \(V_{\max}\) (top right), or \(V_{\text{pos}}\) (bottom left) and filament length, L, on a common logarithmic scale. \(V_{0}\) and \(L_{0}\) correspond to the typical velocity (100 km \(\text {s}^{-1}\)) and typical length (100 Mm) of filaments, respectively. Open circles and crosses represent events with and without CMEs, respectively. The solid lines are described in the text
