We study the potential of a very large volume underwater Mediterraneanneutrino telescope to observe neutrinos from supernova (SN) explosions withinour galaxy. The intense neutrino burst emitted in a SN explosion results in alarge number of MeV neutrinos inside the instrumented volume of the neutrinotelescope that can be detected (mainly) via the reaction \nu_e-bar + p -> e^+ +n . In this study we simulated the response of the underwater neutrinotelescope to the electron antineutrino flux predicted by the Garching model forSN explosions. We assumed that the neutrino telescope comprises 6160 directionsensitive optical modules, each containing 31 small photomultiplier tubes.Multiple coincidences between the photomultiplier tubes of the same opticalmodule are utilized to suppress the noise produced by $^{40}K$ radioactivedecays and to establish a statistical significant signature of the SNexplosion.
