@baoningwu.bsky.social Baoning Wu and Jeena Yun attended the International Joint Workshop on Slow-to-Fast Earthquakes in Japan as recipients of the 2025 Paul Andrew Spudich Travel Grant. Learn more about their experiences and how you can apply in Feb 2026 www.seismosoc.org/news/paul-an... βοΈπ§ͺ

Could drought explain why the southern San Andreas fault has been quiet for more than 300 years? A new #SRL study explores this question, and more. βοΈ

Japanese GSI published the InSAR result of ALOS-2. It may be helpful for the interpretation.

Screen grab of a wrapped interferogram over southern Kamchatka
First Sentinel-1 interferogram from southern Kamchatka! Lots of what I am assuming are tropospheric signals (e.g. over the volcanoes), but I also see long-wavelength fringes that change in azimuth from the NE (~shore-perpendicular) to the SW (~shore-parallel). Optimistic it could be the earthquake!
Literature regarding the 1923 and 1952 #Kamchatka #earthquakes are available at these links:
1923-02-03: www.isc.ac.uk/cgi-bin/Form...
1952-11-04: www.isc.ac.uk/cgi-bin/Form...
Seems that the 2025 event re-ruptured the 1952 area (aftershocks + finite fault). The 2025 didn't rupture across the possible segment boundary; rather, it nucleated near the segment boundary (so did all the foreshocks).

Quickly plot the rough location of the 2025 Mw8.8 Kamchatka earthquake (USGS hypocenter) on Figure 1 in Pinegina et al. (2018). I wonder if the 2025 event re-rupture the northern rupture of the 1952 Mw9.0 event? Also, did the 2025 event rupture across the "segment boundary" at ~N53?

One of the best tsunami education I have seen video on YouTube. Very intuitive animation, especially the parts on wave shoaling and how waves breaks at the coast line.

Apparently surface rupture during the Myanmar 2025. I'm very surprised by the weak shaking along the rupture. I'm not sure if this is the main rupture (I would say no - nonetheless, VERY COOL). Author unknown, location Thazi (to be confirmed)
I am speechless...

I am glad that I open Bluesky 30 mins before the seminar. Seems like an interesting talk.
If you are near the @scrippsocean.bsky.social in La Jolla, come by to the Ritter Memorial Fellowship Lecture tomorrow at 3 pm, I will be talking about the emergence of the German Maritime Observatory (Deutsche #Seewarte).

The whole #MyanmarEarthquake rupture in one interferogram! This is three consecutive wide swath frames of ALOS-2 data, provided by JAXA through agreement with NASA. The line-of-sight (LOS) is ~perpendicular to fault strike, so most of what you see is vertical motion at bends and steps of the fault.

A historical seismicity map shows several #earthquakes of similar size to todayβs M7.7 in Myanmar occurred in the region in the early 20th century, but this section of the Sagaing fault probably hasnβt ruptured since 1839 π§ͺβοΈ

Since nobody asked, here is a map showing where polar bears have been found in Iceland after drifting over from Greenland on icebergs.

Super helpful app recommendation for Watchduty App to track wildfires. They even have large and small animal shelter locations called out on the maps of fire locations, which scores points in my book.
