The HAWC observatory is a ground-based observatory of TeV gamma rays located on the Sierra Negra drop volcano in Mexico. HAWC is sensitive to emission from extended gamma-ray sources, so it is able to search for emission from annihilation and decay of TeV dark matter (DM) particles in galaxies and galaxy clusters. We present the limits for the dark matter annihilation cross-section for the Virgo cluster. We also present computations for possible increased dark matter annihilation flux due to different density profiles and substructure configurations of the Virgo cluster. Such fluxes would increase the dark matter detection capability of HAWC in the Virgo cluster significantly. [ABSTRACT FROM AUTHOR]
