Regular smaller quakes are a good thing. Large quakes often occur due to a large build up of pressure. Regular quakes like this indicate that the pressures are being released, thus no build up, and likely no larger Earthquake in the very near future.
EDIT: I won't feed this post. OSIRIS, if you know the answer why ask the question? Perhaps provide your own views as to wether you believe these
are "fore-shocks" or not before you cut down others responses to your question.
