A new study proposes that a major earthquake along one of the US's most dangerous faults-the Cascadia Subduction Zone-might influence the seismic activity of San Andreas Fault. While the phenomenon of one earthquake triggering another isn't unheard of, some scientists say more evidence is needed.
How ‘the big one’ near Seattle could trigger an earthquake in San Francisco
Are two of the deadliest earthquake zones in North America linked? It's possible—but controversial.

Me: I simply cannot understand how people get so worked up over sports teams. Why do you care so much?
Also me: Cascadia is the BEST SUBDUCTION ZONE EVER and anyone who thinks otherwise is a LOSER, 🏆💯🔥 CASCADIA 4 LIFE BITCHES 🔥💯🏆

Hmm. I know they're not directly connected, but the New Yorker article on the Cascadia Subduction Zone still haunts my dreams.

Japan was formed by subduction of continental plates… it is not a volcano-formed landmass like Hawaii or Iceland.

🗺️ This Fig. shows location of Taftan in the Makran subduction arc.
Taftan is the only one with persistent fumarolic activity.

Je l'ai expliqué à des étudiants de Master MEEF il y a quelques années mais ce n'est pas la démarche que j'emprunte le plus souvent avec des collégiens... En revanche, la démarche par subduction (de copies en retard), je connais.

For the first time, scientists have seen a subduction zone actively breaking apart beneath the Pacific Northwest. Seismic data show the oceanic plate tearing into fragments, forming microplates in a slow, step-by-step collapse.

Le fond de l'océan Pacifique se déchire: le phénomène a été observé pour la première fois
Sur Terre, la subduction survient lorsqu'une plaque tectonique plonge sous une autre. Ce mouvement n'est toutefois pas éternel : prend-il fin dans un terrible fracas, ou alors (plus ou moins) en douceur ? Des scientifiques américains pensent avoir trouvé la réponse.

Yeah, no.
People publishing review papers on using plate tectonics explanations of things like forearc basins by 1978 and in my field region are inventing flat slab subduction by 1976 after having established continues subduction of lithosphere to 600+ km by 1973.

Man... Melissa is a beast. The eyewall shows it best, but the satellite pics... wow.
Mother nature's raw, terrible beauty.
We aren't ready for her full wrath.
The Cascadia Subduction event will startle millions, and even that won't be the worst.

"Magnetometers helped detect expansion zones, seismography helped with subduction zones. What clinched it was Satellite Laser Ranging, a product of the space race.
This allowed for near real time precise measurement of plate movements."
My dude, you can't even get the basic terms right.

Expanding Earth was a very brief thing that was a legit hypothesis between the discovery of sea floor spreading and definitive evidence that earthquakes at subduction zones were dominated by thrust mechanisms at the trench.

The *vast* majority of both would have ended up subducted whenever subduction actually started or delaminating during the formation of the greenstone belt granites.

Once these form the cores of the continents (called cratons or shields or platforms depending on a few things), everybody's more or less in agreement that something resembling modern subduction begins sometime in late Archean or early Proterozoic (say 2.5 to 3 billion years ago or so).

There's ongoing, long-standing arguments for and against some kind of subduction-like tectonics during the formation of the greenstone belts and for and against more overturn and delamination (lava lamp-like) behavior.

New modeling indicates that most shear wave splitting in subduction zones may originate within the downgoing slab itself, challenging previous assumptions about mantle dynamics and rock deformation. doi.org/g977nt
New earthquake model goes against the grain
When a slab slides beneath an overriding plate in a subduction zone, the slab takes on a property called anisotropy, meaning its strength is not the same in all directions.
