Abstract: Since 1997 the neutrino telescope AMANDA at the geographic South Pole hasbeen monitoring our Galaxy for neutrino bursts from supernovae. Triggers wereintroduced in 2004 to submit burst candidates to the Supernova Early WarningSystem SNEWS. From 2007 the burst search was extended to the much largerIceCube telescope, which now supersedes AMANDA. By exploiting the lowphotomultiplier noise in the antarctic ice on average 280Hz for IceCube,neutrino bursts from nearby supernovae can be identified by the inducedcollective rise in the pulse rates. Although only a counting experiment,IceCube will provide the world-s most precise measurement of the time profileof a neutrino burst near the galactic center. The sensitivity to neutrinoproperties such as the theta13 mixing angle and the neutrino hierarchy arediscussed as well as the possibility to detect the deleptonization burst.
