A moderate erathquake occurred tonight in El Salvador, this time the origin of the quake was a local fault line in weatern El Salvador and not the subduction zone. It's interesting to note that this earthquake was strong enough to be felt in San Salvador and that's unusual as inland quakes are felt only in the areas near the epicenter. No damages are repoted yet but the intensity was fairly high near the epicenter.
