International audience Icecube neutrino detector a cubic kilometer in South Pole, traces energetic TeVs-PeVs neutrino signals by their cascades or better by their tracks inside its icy volume. Cascades, explosivespherical showers in icy, are mostly for electron or tau or neutral current, tracks are made by muons. High energy tau tracks might show a birth place cascade and a second decay tau shower,allowing a peculiar directional track. In general hundreds TeVs-PeVs Cascades show very poor directionality. Therefore they are nearly blind to disentangle the source event. Therefore wesuggest to neglect such cascades in future Gen-2 Icecube. Indeed the most interesting signals are the tens TeVs up to PeVs muon upgoing tracks, either born inside, HESE, or outside Icecube: thetrought going muon tracks.
