bilby Aftershock is a terrible word when you've just been through an earthquake. 10 letters that keep you awake at night :-( Oct 29, 2009
reesetee Ah, of course. It's not as though the giant word "aftershock" at the top of this page didn't alert me to that fact. :-\
I thought "trembler" was odd, too. I've always heard it called temblor. Apr 8, 2009
bilby Interesting use of trembler in the NYT citation. I've never seen/heard it used this way before. It makes some sense although perhaps there is some (understandable, given the root) conflation with tremor. Apr 8, 2009
Prolagus This article refers to the aftershock. The earthquake that killed all those people was 6.3, as far as I know. Apr 8, 2009
reesetee I'd read yesterday that they measured it at 6.3. Has that been revised? Apr 7, 2009
Prolagus In the early evening Tuesday [today], a particularly strong aftershock sent rescuers and residents fleeing from damaged buildings in L’Aquila as chunks of concrete fell from crumbling buildings, The Associated Press reported. The news service quoted the Italian news agency ANSA saying the trembler killed another person; it reported that the United States Geological Survey said the quake measured 5.6, but Italian seismologists put it at 5.3.
