Slow Slip in the Cascadia Subduction Zone: Thinking Outside the Plane

Large episodic slow slip events in Cascadia can be modeled as stick-slip at the interface between a viscoelastic layer above an elastic layer The model is motivated by (a) slip in an event < plat...

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. ⚒️

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

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!

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)

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 today’s M7.7 in Myanmar occurred in the region in the early 20th century, but this section of the Sagaing fault probably hasn’t ruptured since 1839 🧪⚒️

The JMA panel acted quickly, deciding less than 3 hours after the earthquake not to issue an advisory. www.japantimes.co.jp/news/2025/01...

Miyazaki quake falls short of triggering Nankai Trough megaquake advisory

Though Monday's temblor struck a similar area to one in August that sparked the first advisory, no such alert was issued.

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.
