Unfortunately the "Latest Felt Quakes Map" at http://www.weatherwatch.co.nz/geonet doesn't work because the website has exceeded 25,000 map loads in a day.

So the tsunami was 1 foot Hawaian style. Doesn't seem too big...

tsunami wave != typical wave. A wall of water that just keeps coming. A water bulldozer.

"Tremor"? I mean, IMO anything 7+ is more than a tremor.

Videos of the earthquake: https://youtu.be/WcljQHCUm_o?t=20 https://youtu.be/EsnS28ulJUw News say it's 7.4 - 7.8 magnitude.

This is not footage from this earthquake. This earthquake hit at 12am in the morning so these videos are obviously of another time.

> at 12am in the morning

Argh, had to look that one up. 'Just after midnight local time'.

Less a wave, and more a rapid increase in sea level lasting for a few minutes.

Magnitude 7.5 earthquake. For reference, I felt this in Hamilton, a bit under 1,000 KM away. First earthquake I have ever felt. Hamilton never, ever gets earthquakes.

Nevertheless, NZ infrastructure is built to withstand this sort of stuff. Only $100m-1b economic damage is expected, no casualties expected.

Hmm, I doubt that these videos are the NZ quake. It happened at around midnight, and those videos are in broad daylight.

EDIT: I see others have already corrected this misinformation.

Does anyone know if there is any special effort to construct buildings that can withstand reasonable earthquakes in New Zealand?

Christchurch seems particularly prone to quakes in New Zealand. I hope the people of New Zealand are safe.
