Just as a quick note to the mention of Greendale, you may be aware of the fact that Christchurch, New Zealand, has been going through a very stressful time, having experienced over 10,000 earthquakes within the past 18 months, or so. At least one of them caused serious loss of life and damage to property. The shake that set this whole lot going happened in the very early hours of September 4th, 2010. Fortunately, while quite damaging in some areas [it was rated at about M 7.4, from memory] it did not cause any loss of life. This shake was centred at Greendale when a, previously unrecorded, fault-line moved, and very spectacularly too, I might add. I am not aware of how any of the Hann Clan were affected in that area.
