NEW: After today's magnitude 7.7 quake off the Pacific coast of Japan, the country has issued a 'megaquake advisory', suggesting there's a 10x greater risk of a magnitude 8.0+ quake in the coming days.
I break down what this means for @sciam.bsky.social www.scientificamerican.com/article/risk...
I'm glad that the 1906 earthquake still makes you think of me, haha!
Most of the ones I was about to mention are in that same issue!
(I also saw a talk at the @seismosocam.bsky.social meeting this week looking at whether faults other than the San Andreas were involved in the northern part of the rupture, but the paper isn't out yet.)
Ohh! Til hamingju með afmælið!
I know of a lot of papers looking at the source physics and ground motion distribution for 1906, but I'm not aware of a consolidated retrospective/review-style paper. Are you still interested in those?
Volvo the cat seems to also be a regular.
Wow. It’s the 120th anniversary of the Great San Francisco Earthquake and the Chronicle has a pretty good write-up on Northern San Andreas earthquake mean recurrence intervals.

Some of these listings are testing my resolve not to buy yarn that isn't for a specific project.
My CADFW biologist friend was so excited to tell me about this “bear” incident when it happened.
@valah.bsky.social Ertu hér á SSA?!
Using Precariously Balanced Rocks as constraints on earthquake ground motion isn't unusual for the tectonically-active west coast of North America, but it's very cool to see people extending PBR research into areas that aren't a plate boundary anymore!
There are so many sounds around here in general, I can't tell if any of them was the Artemis reentry boom? Or just an airplane? Or someone's souped-up bass in their car?
I assume clipping one of the giant letters will lead to a larger shockwave!
Allergy vaccine???!!! That isn't a weekly shot or a daily pill?! HYPED!
This is a great chance to do citizen science, and to help track the behavior and effects of the shockwave as it propagates away from the reentry site!
This helps not only with understanding this mission, but also possible effects of other falling space debris or meteors.
⚒️🧪 Got an @earthscope.org email saying that the #ArtemisII re-entry shockwave may be audible in coastal southern California between 17:00 and 17:15 PDT or so today!
If you're in this area, fill out a USGS felt report with details of what you do (or don't) hear! earthquake.usgs.gov/earthquakes/...
The latest eruption at Kilauea appears to be starting! We should see large lava fountains soon. Tune in live here: www.youtube.com/watch?v=gXKu...
Always a good approach!
The aftershock sequence of the 2019 Ridgecrest, California earthquakes has lasted longer than the Confederacy!
I love the wordplay aspect of it so much!
There is a canyon in the hinterlands of North Iceland, Nautagil, which translates perfectly simply to Bulls, Canyon.
Except no, the "naut" does not come from Icelandic naut, but from astro-naut.
Named after they trained there
On the Artemis II livestream the other day, they mentioned that this crew trained in Iceland as well!

Katla also enjoyed The Terror!
I know this isn't the main point at all, but I'm very distracted/frustrated by them plotting two placenames on top of each other on that map.
Imagine having the most incredible day of your life crashed by having to talk with that guy...
The sense of awe and sense of humor of this crew is just making everything even more incredible!
I love how they said they're gonna need to come up with some new adjectives to cover this. Come up with them, Integrity! We'll use them!
Very rude of my schedule to require that I go teach a class instead of watching more Artemis II stream.
George was vital and ageless, generous and cheerful, and so not full of himself. I think he knew how lucky he was to be at the right spot back in 1964, yet modest about the work it took to interpret the Anchorage earthquake boldly and correctly.
Aw nooooo!
97 is such a good run, but from the times I met him during my postdoc, he seemed like one of those people who would be around forever and would always have more stories and insights.
