3D geologic framework matters!!!.
Traditionally, we model global navigation satellite system (GNSS) measurements of how the Earth deforms during earthquakes with a 1D Earth structure. What if we didn't assume a 1D structure? Fadugba et al. show us that 3D matters more than we think:.

USGS joins forces with UW to document geologic evidence for shallow megathrist slip offshore WA and northern OR! Modelers enjoy🙌.
Ledeczi et al. find a ~30km band of active splay faults at the deformation front of the Cascadia subduction zone, while faults landward are covered in sediments. Such active faults are likely to slip coseismically during megathrust events. Read more:

My colleagues are rad!.
The @USGS is providing support for an innovative project between @USACESPN, @ca_coastal, and @redwoodcityport to increase marsh #resilience to #sealevelrise in #SanFranciscoBay:

Have you ever wondered what we do with those cores back in the lab?!? Check this out👇.
By collecting information about the past found within core samples, #geologists contribute towards a better understanding of how conditions may change in the future. Ready for a virtual tour of the @USGS Sediment Core Lab? We thought you'd never ask!

Fascinating👇.
A very nice upside to naturally-occurring geothermal systems is that they can thermally destress faults, meaning they can reduce seismic hazards. The Ridgecrest M7.1 really demonstrated that when it couldn't rupture thru the Coso geothermal field.

This is why we need systematic bathymetry along all offshore active faults👇.

Check out this new work by John Desanto and others!👇.
Check out some recent work adding in seafloor geodetic observations for the Mw 7.8 2020 Simeonof, Alaska earthquake. The addition of this data confirms that the shallow megathrust did not rupture during the event.

Welcome!!🙌.
A new pack of gray wolves has been confirmed in the Sequoia National Forest region of Tulare County, a remarkable 200 miles by air from the nearest other California packs via @lisamkrieger.
