Tsunami warning issued. The East Coast of the North Island from CAPE RUNAWAY to TOLAGA BAY. Strong and unusual currents and unpredictable surges near the shore are expected in the following areas. This means a threat to beach, harbour, estuary and small boat activities. The East Coast of the North Island from PORT CHARLES to CAPE RUNAWAY including Tauranga, Whakatane and Opotiki. And from TOLAGA BAY to MAHIA, including Gisborne. As well as GREAT BARRIER ISLAND, and the CHATHAM ISLANDS. The first waves were expected to reach New Zealand in the areas around East Cape about 3:14 am. Quote Link to post Share on other sites
eruptn 95 Posted March 4, 2021 Share Posted March 4, 2021 A second large event in the Kermadecs .. it may create some coastal issues. Take a peek here to see if there is any activity on the tsunami gages; https://www.geonet.org.nz/tsunami Quote Link to post Share on other sites
Fish 0 Posted March 4, 2021 Share Posted March 4, 2021 I really am getting sick of all these alarms, alerts, warnings, severe warnings. Can't I just have my breakfast without worrying about the sky falling on my head? Yesterday we had a 'severe thunder storm warning'. We had some good thunder, but I couldn't understand why it wasn't just a warning of thunder storms, rather than 'severe'. At least they didn't set the car alarm noise off on my phone this time, like on last Saturday night, when I was trying to chill out with the missus and watch a movie. We're still at L3, and that haven't had a damn single case of community transmission. Planning on what to do this weekend, can't take the kids sailing (yet), maybe I'll go windsurfing, no- threat of death in near shore water activities, f*ck. Can't watch the America's cup...

wheels 543 Posted March 4, 2021 Author Share Posted March 4, 2021 Stuff have posted thier news story that makes it sound like many on the East Coast need to evacuate. I think they have simply cut and pasted the warning advisory, if one experiances a shake in which they cannot stand up in. It's worded/put together poorly I feel and could make some panic reading it the way written. Quote Link to post Share on other sites
Fish 0 Posted March 4, 2021 Share Posted March 4, 2021 I would complain about Stuff click-baiting, but I can't keep up, now there is a Mag 8, and everyone is being told to run to the hills? I need a cup of tea.... Quote Link to post Share on other sites
wheels 543 Posted March 4, 2021 Author Share Posted March 4, 2021 8.1 and only 19K deep. Does anyone live on Kermadecs? Evacuation has been called for everyone along the East Coast from BOI down to Whakatane. Quote Link to post Share on other sites

eruptn 95 Posted March 4, 2021 Share Posted March 4, 2021 DOC have staff on Raoul Island, but they are not on site at present, so there is no one. The links to Raoul have gone down, hence no data showing here: https://www.geonet.org.nz/tsunami Maybe a hint of something at Barrier Quote Link to post Share on other sites

eruptn 95 Posted March 4, 2021 Share Posted March 4, 2021 Hi KM No 1 - Is that from the 1st rattle at 2:30am +/- or something else? If from the 1st shack why only East cape do you think, I'd have expected Northland and Barrier to have twitched as well. Most of that is actually the ground going up and down with the quake, hence appearing as water level changes. Note the high frequency No 2 - Below those are the signs you mention as now arriving? On the Barrier one the wiggle goes left a far bit, would that be smaller waves arriving from the 1st rattle? Yes that's the long period signals starting to arrive about 40 cm No 3 - Those spikes would be due to the quake. The grey either side of that, and can be seen on others, is that just your average day to day bigger waves that inhabit oceans? That is the aftershock, the high freq stuff. The light grey is the swells, the black is filtered to get rid of the higher freq swell signals Hope that helps. Looks like some serious low amplitude coastal surging ahead. 30-40cm tidal rise and fall over maybe an hour. Quote Link to post Share on other sites
Fish 0 Posted March 4, 2021 Share Posted March 4, 2021 Hey Mr Eruptn, how come the whole of NZ including Stewart Is is on alert for strong surges, but not the coast around Chch and Timaru? Quote Link to post Share on other sites
ex TL systems 63 Posted March 4, 2021 Share Posted March 4, 2021 We are overlooking whananaki estuary and seeing surges coming in. No damage so far though. 1 Quote Link to post Share on other sites

That will be a result of the bathymetry and physics of the calcs used. Note its less than 30 cm, not no surge. Quote Link to post Share on other sites
