not really a triple junction is it? what is going to happen here over the next million years or so do you think? You basically have two slabs subducting in opposite directions racing towards each other obliquely on strike-slip fault (albeit with a bit of horizontal movement tossed in). The bit in the middle is obviously going to be deformed every which way to Sunday, (it already is) but sooner or later those subducting slabs are going to meet each other at depth. What happens then? Do they stick? Will some kind of transform fault form and one of the plates start subducting somewhere else? Are there any precedents for this kind of thing? sorry, lots of questions, I know., but it is hard to envisage.
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.
That is a top notch crew of authors, know many of them really well. It is certainly not a simple plate boundary.

Hey all! Nate, here. Just wanted to let you all know that RP headquarters and the team are all ok. It has been quite the experience. Our office escaped all damage, however my personal house was pretty trashed inside. Lot's of broken stuff and no power for about 16 hours. My kids and I were able to get things cleaned up and we were thankful we were fairly well prepared with generators and other supplies. Alanna, William, and the rest of the team are all ok and faired well. Thanks for the concern and thanks for listening!

Great video! The similarity to Kaikoura struck me immediately and had me chasing up Kaikoura and triple junction.. and came up with "Triple junction kinematics accounts for the 2016 Kaikoura earthquake from Xuhua Shi et al. which invokes a separate plate on the accretionary edge of the convergent margin starting from Kaikoura and extending all the way up to Tonga. How has this been received in the community? Does it have any credence?
Lots to unpack in this paper. I understand the desire to create a microplate between the volcanic arc and the subduction zone (essentially the forearc and the accretionary wedge) but then we could also invoke the same here in Cascadia land. It is clear, from paleomag and geodetics, that our forearc is moving at a different relative velocity from the backarc (North America) much like what these authors see in NZ. There are indeed great similarities between the two tectonic systems and they are really complex. NZ's is much more seismically potent as it produces waaaay more significant eqs. than ours. Thanks for pointing out this paper.

Thank you for the update! Happy to see that you all made it through with only minor damage. Cheers.

Here's a little information about the Mendocino Triple Junction (MTJ) area that just spawned this earthquake. One reason we are one of most seismically active areas in US.
Fascinating Geoff. I didn't realize that the subduction was moving north like that. Thank you for the rabbit hole...
2:30 something last night, MyShake yelled at me "EARTHQUAKE EARTHQUAKE EARTHQUAKE" and the little indicator told me it was a 6.3 and I should DROP! COVER! HOLD ON!
but we were 200 miles from the epicenter, so didn't feel a thing. And I'd forgotten I'd installed the app. But, it seems to work.
