I'm from Christchurch, contacted family there. There's been mass evacuations from the coastline. Tsunami's have started but they can last for hours. Kaikoura has already had a a surge measured 2.5m, if this is the case the waves will get worse before they get better. But NZ is pretty prepared for these things, so hopefully everyone scampers to the safe distance from the coastline. I worry about the Chatham Islands, they're directly east of the epicentre, and Tsunami's travel very fast. I hope they've all gotten to high ground.
- EdwardDiego 10y agoNo, that 2.5m high one was the worst of the waves. http://images.geonet.org.nz/tsunami/plots/latest/detide.png http://images.geonet.org.nz/tsunami/plots/latest/detide.png It was most likely caused by a movement of sediment into the Hikurangi Trough.
- zoltrain 10y agoThat would make a lot of sense. Civil defence must be being pessimistic in there predictions, as you should be. It's better to be away from a coastline if there might be a tsunami and there isn't, then the other way way around.
- Freestyler_3 10y agoThen why is it still reported that waves 3-5 meters are expected?
- zoltrain 10y agoCivil Defence are doing their job, getting people away from the coastline. There maybe Tsunami's there may not be, better not to take any risks. Must be protocol when any of the Tsunami alarms are triggered.
- EdwardDiego 10y agoAlso because your coastline can fundamentally change how it affects you - the gauges near Christchurch measured 0.5m appx at the highest, whereas an (empty, thank goodness) house at the end of a funnel shaped bay in the same vicinity got hit by an estimated 2 - 3m wave.
- hinkley 10y agoIsn't Christchurch still finishing the rebuild from the last big quake?
