Video / Claudia Maaka / Waiapu Civil Defence / Gina Pewhairangi / Dean Purcell It comes as GeoNet has published data from tidal gauges, showing how a tsunami reaching up to 40cm high was measured at Great Barrier Island soon after the events. This afternoon, University of Auckland coastal geomorphologist Dr Murray Ford tweeted a before-and-after satellite view of Raoul Island. The first decent cloud free image of Raoul Island after the 8.1 quake and tsunami last week. Lots of landslides. @NZNavy HMNZS Canterbury anchored just offshore with @gnsscience and @MetService team.
