For the first time, we demonstrate how an MHD avalanche can occur in a multi-threaded coronal loop. A single unstable thread destabilises neighbouring fields to intiiate the avalanche. Variations in the magneitc structure of the neighbouring threads influences how the avalanche develops. The total magnetic energy released to heat the coronal plasma exceeds that of the single unstable thread. The implications for coronal heating are discussed.
