The observation of PeV cosmic neutrinos is an essential tool for understanding cosmic ray acceleration and source evolution. These particles are produced either within astrophysical sources or when ultra-high energy cosmic rays interact with the Interstellar medium. Neutrino signals may accompany electromagnetic and gravitational messengers, or they may be the primary signal at the site of cosmic ray acceleration. Neutrino messengers from transient or flaring sources (AGN, GRB) are a topic of intense study. The observations of UHE gamma-ray emissions from GRBs with Cherenkov telescopes in the last years and the detection of a 18 TeV photon from GRB221009A by LHAASO pushes experimental efforts to observe possible correlated neutrino emission. In principle neutrinos can be detected also by Air Shower arrays through the observation of Horizontal Air Showers (showers with a zenith angle >70 deg). In this talk this topic is discussed and preliminary sensitivity of an array like LHAASO presented.
