First snowfall at lower altitudes! It’s officially winter.

To illustrate this complexity, here is a figure from Nishikawa et al. (2023) with the recent M6.8 earthquake added as a yellow star. This event is located just North of the Tohoku-Oki rupture and possibly within the 1992 ultraslow Sabrina-Oki earthquake. ⚒️🧪

I generated a quick map for the current earthquake sequence near Japan, in a complex area of the subduction zone (or maybe it’s only considered complex because it is so well instrumented…) ⚒️

I realize this is turning into a fall colors account, but I’m still pretty excited about experiencing real seasons, so here is one more! 🍁🍂

Peak fall colors in some of the valleys now. No filters needed, just nature! 🍂🍁

Perfect hiking weather and fall colors near peak in the Alps!

We went to Arco over the weekend for the fall foliage and the Rockmaster climbing and bouldering festival. Both were very enjoyable!
(And no, those are not 🍁 pics.)

Still exploring the Swiss Alps, fall is probably my favorite season there.

For comparison, I have attached a tectonic map of this tectonically complicated region from Schellart et al. (2023) with the recent earthquake shown as a small purple star.

Catching up on a few earthquakes this evening. The M7.6 Drake passage earthquake yesterday appears to have been an intraplate strike slip faulting #earthquake , unlike the M7.4 earthquake a few months ago in the greater area, which was subduction related. ⚒️🧪

Nice day for a hike today. Lots of #mushrooms in the woods confirm that fall has arrived!

M4.3 shallow #earthquake near Berkeley, CA a few hours ago, strike slip mechanism, possibly on the Hayward Fault Zone. ⚒️🧪

We have now entered the “this looks scary” part of the house renovation project.
(Yes, there is now a large hole in the roof.)

Nobody here cares about F1, but even less about #motoGP ! But sometimes when the world is going crazy, you want to watch motorcycles go very fast. And Misano is a good place to do that.

Today’s M7.4 aftershock of the Kamchatka #earthquake was located in the Northern section of the mainshock rupture, where most aftershocks (in pink/purple) and foreshocks occurred. This event was also an interface thrust earthquake, but slip was concentrated at a greater depth. ⚒️🧪
