It's very important how they communicated to public e.g. "chance for a damaging quake is unlikely" is not same as "nothing to worry about". It's just too silly of them if they actually said "nothing to worry about".It doesn't matter if someone says the chance for a damaging quake is unlikely. If a quake happens, you don't pretend that it's not happening, you use common sense and do what you would normally do. I don't see anywhere that a scientist told anyone that if a quake hits to disregard it.
