We measure the horizontal ( cos(θz) <0.14 corresponding to a slant depth cut 14 kmwe) neutrino-induced muon flux (Eμ>1.8 GeV) in Soudan 2 to be 4.01 ± 0.50 ±0.30 ×10-13 cm-2 s-1. From the absence of horizontal muons with large energy loss, we set a limit on the flux of muon neutrinos from active galactic nuclei.
