This situation is no different now in terms of tsunami and people should not worry about this. Tsunamis in Christchurch largely come from South America with 12 hours warning.
He points to faults in the North and says they are "locked up" but can break into a significant earthquake "once in a very, very long time". The work they are doing confirms that quakes in the Christchurch area are very rare events. "It is very much, wrong place, wrong time for the Christchurch city in the 21st century".大废话！！！
13:42pm - Mr Berryman says it looks like we have "filled up" the expected amount of after shocks. He says this is good news. This issue is rather complex but as far as I can understand Mr Berryman seems to be saying that until the recent quakes Christchurch had fallen behind the expect level of aftershock activity expected since the September quake. That is there was some "missing energy" (as Bob Parker calls it), that has now been accounted for following these strong Christmas/New Years shakes. Mr Parker and Mr Berryman agree this is good news. He shows a graph which shows the actual aftershock activity line now converging on the expected number.
This means it is quite probable that quakes will gradually decline. This doesn't mean the quakes will stop, he can guarantee fives in the coming months but hopes they will be mainly offshore. He does not think they will be damaging.
The meeting has broken for questions video of this will be available online shortly.
