Sadly, I doubt only 8 were killed, unless it's a VERY sparsely populated area. Either those 1000+ collapsed building were very old, or there simply isn't a building code and compliance culture in that area. By way of contrast, the 1989 Loma Prieta Earthquake probably did far less damage in buildings collapsed (and possibly in people killed), but was over 10 times the strength (magnitude scales are logarithmic, not linear).
