We conduct observational studies to explore the role of kinking in coronal eruptions. Our recent work has shown evidence supporting the role of writhe of the filament axis as a possible driver and regulator of filament eruptions. We identify coronal X-ray source emission occurring beneath the apex of a writhed filament with reconnection driven by kinking motions. We indicate that quasi-static kinking motions induce a catastrophe in a filament/cavity eruption. We find brightening soft X-ray and EUV features propagating along filament legs down to the solar surface during filament eruptions, suggestive of heating in the current sheet formed at the interface of writhed filaments and ambient field. We propose that weakening of magnetic tethers that anchor either leg of a twisted and/or writhed flux rope which supports the filament result in whipping and/or rotating motions observed in “zipper-like” filament eruptions.
