Using a simple cellular automata with stochastic rules, we show the possibl
e emergence of thermally activated avalanches (power law distributed) in ty
pe-II superconductors. Scaling relations between the exponents characterizi
ng these distributions and those obtained from field-driven experiments are
derived and proved through simulations. It is also shown that the conditio
ns for the appearance of these avalanches are independent of the pinning me
chanism. The relevance of our simulations for recently reported experimenta
l results is also outlined.
