Powerful mechanical-driven outflows in the central parsecs of the
  Low-Luminosity Active Galactic Nucleus ESO428-G14
  Low-Luminosity Active Galactic Nuclei (LLAGN) are characterized for low
radiative efficiency, much less than one percent of their Eddington limit.
Nevertheless, their main energy release may be mechanical, opposite to powerful
AGN classes like Seyfert and Quasars. This work reports on the jet-driven
mechanical energy and the corresponding mass outflow deposited by the jet in
the central 170~parsecs of the nearby LLAGN ESO428-G14. The jet kinetic output
is traced through the coronal line [Si vi] $\lambda$19641 \AA. It is shown that
its radial extension, up to hundreds of parsecs, requires a combination of
photoionization by the central source and shock excitation as its origin. From
the energetics of the ionized gas it is found that the mass outflow rate of the
coronal gas is in the range from 3$-8$~M$\odot$~yr$^{-1}$, comparable to those
estimated from H I gas at kiloparsec scales in powerful radio galaxies.
