Description
By separating $\nu_{\tau}\to\tau$ conversion from $\tau$-shower generation,
the Earth-skimming $\nu_{\tau}$ method allows for huge target mass and
detection volume simultaneously. In part motivated by recent IceCube
astrophysical PeV neutrino events, the planned NTA observatory will
have three site stations watching the air mass surrounded by Mauna Loa,
Mauna Kea, and Hualalai on Hawaii Big Island, plus a site station at
the center watching the lower night sky. Sensitivities equivalent to
$> 100$ km$^3$ water and pointing accuracy of $< 0.2^\circ$ can be
achieved with Cherenkov-fluorescence stereoscopic observation for PeV-EeV
neutrinos that is almost background-free. With design based on experience
from the operating Ashra-1 detector, and the goal of clear discovery and
identification of astronomical $\nu_\tau$ sources, a new International
Collaboration is being formed to probe for cosmic proton accelerators.
