Chile’s Calbuco volcano erupted for the first time in more than 40 years this April, sending mushroom-shaped plumes of ash more than six miles into the sky. The German-based crew from Timestorm Films happened to be filming nearby when the eruption started, and captured amazing footage of the ash in all its apocalyptic glory.

Enjoy their serendipitous high-resolution timelapse below.
