they're reporting this the biggest quake on record in Philly area. although the one in 2011 (centered in Virginia) shook us a lot more. I saw the frickin' wall and floor waving.
I was at work when that one hit. In a mobile trailer type thingy, and was standing in the hall outside my office talking to a co-worker when I notice my snake plant swaying. I said: "I think that was an earthquake." He hadn't even noticed. When I got home (closer to the epicenter than work), Middy (remember Middy?) was beside herself. As if to say: "I didn't do it, Mom!" Nothing off the walls, but all the pictures were askew and some things were knocked over.

The second part of the video, shot down the hall is great as well, can really see the pop of the p-wave.

lol they just showed that video on the news.
we're about 60 miles from the center. wasn't that shook. felt more like the floor vibrating.
there was a 2.2 in the same area last week. pre-shock they are saying

I was at USGA site before they even posted. LOL

Jrzy, did something alert you to the beginning of the shaking, like a banging sound, a pop or a jolt? The low rumble was likely the shear wave (accompanied by swaying motion).

Jrzy and I live pretty close to each other...and I heard it...a loud rumble...and then the platter of my turntable started banging into the "walls" of the deck behind me. Given the rain, and the fact that a tree came down in the woods by my house, I was worried that one of the larger trees had fallen on my house.

Ignimbrite flare-up - I'd like to see that paper. The IFU the western US experienced (ca. 20-30 Ma) was due to the Farallon slab collapsing into the mantle and really hot asthenospheric material contacting continental crust...boom!
As to the question about future prospects of the diminishing Alpine fault, I don't know. I'll have to look for another example of opposed polarity subduction zones mating.
It is definitely geology on steroids in Aotearoa

The most recent paper I read is that NZ is currently in the middle or even beginnings of an ignimbrite flare-up so I wouldn't go with relative stability, unless you take some ridiculously short time-frame for geological processes. The rest is pretty mundane stuff that could apply just about anywhere on the Pacific rim.
The actually reality is that NZ geology is scary as all hell but equally fascinating.

thank you bard!
New Zealand is located in the Pacific Ring of Fire, a region of intense volcanic and seismic activity. The country is currently experiencing a period of relative stability, but this is expected to change in the future.
Over the next million years, New Zealand is expected to experience a number of tectonic events, including:
- Earthquakes: New Zealand is currently experiencing a number of earthquakes each year, and this number is expected to increase in the future. The largest earthquakes in New Zealand are capable of causing significant damage and loss of life.
- Volcanic eruptions: New Zealand is also home to a number of volcanoes, and these volcanoes are expected to erupt in the future. Volcanic eruptions can cause significant damage and loss of life, as well as release harmful gases into the atmosphere.
- Tsunamis: New Zealand is also located in an area that is prone to tsunamis. Tsunami waves can cause significant damage and loss of life, as well as inundate coastal areas.
These tectonic events are a natural part of the Earth's evolution, but they can also pose a significant threat to the people and infrastructure of New Zealand. It is important to be aware of the risks associated with these events and to take steps to mitigate them.
There are a number of things that can be done to mitigate the risks associated with tectonic events in New Zealand. These include:
- Building codes: Building codes in New Zealand are designed to withstand earthquakes and other tectonic events. These codes can help to reduce the damage caused by these events.
- Emergency plans: New Zealand has a number of emergency plans in place to deal with the aftermath of tectonic events. These plans can help to reduce the loss of life and property.
- Education: It is important to educate the people of New Zealand about the risks associated with tectonic events and how to stay safe. This education can help to reduce the impact of these events.
