I think the "work" in particular was a rough choice because it's not immediately clear whether they're using it as a verb or noun. And "set off" is bad for similar reasons. Something like "deadliest tsunami triggered preparations for the next one" or "deadliest tsunami inspired readiness for the next one" might be better. Or even "lessons from the 2004 tsunami help us prepare for the next one".
