The influence of a random spectrum of lower hybrid waves on the evolution of tearing modes in a tokamak plasma is investigated. For rather modest levels of fluctuations, it is found that new tearing instabilities driven by turbulence are excited with significantly enhanced growth rates and comparable real frequencies. The growth rates for the newm= 1 andm= 2 modes vary as fractional powers of &tgr;Rand &dgr;, where &tgr;Ris the turbulence induced diffusion time and &dgr; is the ratio of Alfve´nic time to the ion gyration period.
