 Multi-messenger studies means studying at least two or more cosmic messenger particles to study the transient phenomena in our universe. Using multiple messengers greatly extends our understanding of the universe. The cosmic messengers include the electromagnetic waves, cosmic rays, gravitational waves, and neutrinos.

 Up to now, there are three successful multi-messenger detections: 1) In 1987, the observation of the supernova 1987A, where neutrinos are observed in neutrino experiments about 2 or 3 hours before the visual observations. 2) 30 years later in 2017, the observation of the gravitational wave and the electromagnetic observations of the gamma ray burst observed by Fermi and Integral. 3) TXS 0506, where for the first time, blazars are identified as one neutrino source.

 Among those multiple messengers, neutrinos are an important type of messenger. Neutrinos are neutral and only interact via gravity and weak interactions. So they can provide good positioning for sources that may not be easy via the electromagnetic method.

 As neutrinos travel with nearly the speed of the light, a real time or near real time alert system based on neutrinos is possible - this is vital for follow-ups for those high energy transient sources that are time-dependent with the flux quickly varying.

 KM3NeT will be integrated a part of the global multi-messenger community, we will (soon) be able to: 1) to receive external alerts (from GCN https://gcn.gsfc.nasa.gov/ which ) and search for correlated neutrinos in KM3NeT. 2) to send neutrino alerts that we observe in KM3NeT and send them out to external experiments for external follow-up.
