Its a friggin volcano. What do they expect?
As a geologist, I've had to explain to people why their house went into a sinkhole, or was flooded out, etc.... in places any geologist worth his salt wouldn't build. So I'm very sensitive to people not really understanding what they're getting into...perhaps too sensitive to it. So I have sympathy for people having questions.
Part of the issue in cases like this isn't the technical side itself, but the questions about response. For example, these people are probably feeling like they aren't getting the latest information from authorities and experts. While the experts don't have all the answers, sometimes there are things that could be passed on. And sometimes the authorities have more understanding than they share with the residents.
But dang...building on the leading-edge of the fore island of a hot-spot archipelago, you don't get much crazier than that!
