Strong shake for over 20 seconds in Hutt City. Didn't have the brake on and it moved my wheelchair. Have some paintings to straighten and some glasses in a cabinet to pick up. These events are always a bit spooky at home by myself

I can't remember if I felt it or not here in Napier and I know you don't care :-)

Love it.

Causes rage with me for the facebook users out there.

Soooo many people feel inclined to post on the.. yes, automated.. posts from Geonet upped to social media With 'Felt in x'

1. they ain't ever going to read them

2. its not a felt report unless its logged on a submission form

3. the ground we are all so magically stuck to moved, when it moves a lot. More people feel it. OF COURSE YOU FELT IT!!!!!

Because science.

In other news, good to see no reports of damage, etc

Looks like just over 2 minutes to reach Christchurch from GeoNet's recorded time.

That's about 600km, so about 5km/s - seems about right.

My son called me - he's working on one of the upper levels of the new hospital building in Chch and says it felt quite strong there. It would have been interesting to see how much (if any) the superstructure slid on the sliders. It's designed to move 600mm in any direction.

I'll be interested to see if there is any damage in our apartment. Building is designed to sway in wind/quakes and we are 11th floor. Things moved about 3 feet in the Kaikoura Quake.

My wife texted me from Wellington to say they were all under their desks. I replied I was trying to avoid my tea spilling but other than that, carrying on as usual.

I was walking along the footpath when it hit. I thought it was thunder firstly, because there was a loud bang before the ground started rocking.

frankv: Felt strongly in PN.

I happened to be in PN for work this arvo. Walking around (second level at Central Energy Trust Stadium) so didn't feel it. Had to stop and ask a few colleagues why they were so silent and looking wide-eyed

Can't explain that, but IME, if you are walking, you wont feel it as much or at all possibly

Here is why it was hardly felt near the epicentre but was felt south and further away

Geonet said: "Large, deep earthquakes like this usually cause fewer aftershocks than shallower ones. As this was a very deep quake, you can see from the pattern of felt reports that the energy travelled along the rigid subducting slab on the east of the North Island."

Rigid rock is better at transmitting earthquake waves than mushy rock. So when an earthquake happens in or near this slab of subducting plate, most of the quake’s energy (and therefore shaking) travels up and along the slab to the surface. The energy that travels straight up to the surface has to travel through the softer, semi-molten rock, which "dampens" the waves. This means that fewer people around the epicentre will feel these types of earthquakes.
