A long long long way away and I think that NZ and other islands will shelter most of the East Coast but as Alex Zadnik sent in a text message to me, where's Tassie's warning???

Hmmmmmmm....do small offshore islands actually have much of an impact on Tsunami shielding? Some serious speed (period) in a Tsunami so one would think that you'd get some damn good refraction around small offshore islands.

I think you mean "Where's Tassie?"

In all seriousness though Craig, based on this map, Tassie should feel the effects first, so it's a little worrying that the BOM have omitted them from the warnings?

Forecasts aren't indicating any major tsunami which is good. Other DART observation to the east-southeast only picking up a 20-30cm signal..
