Today, the elected officials behind 2025’s failed public lands sell-off attempts introduced a joint resolution to undo the National Monument's Management Plan.
This assault on a national monument marks a significant escalation in Congress’ use of the CRA. Read more: suwa.org/senator-lee-...
Oh no! That sounds not fun!
Quick displacement assessment using the DIC tool of Bickel et al. github.com/bickelmps/DI... with Planet imagery. Very large and well resolved displacements.
Nice idea! I have a similar result using Bickel et al. DIC

HIGHWAY 229 LANDSLIDE UPDATE – 03
The landslide is still settling and has destabilized the terrain in the affected area. The impacted area remains in a LEVEL THREE – GO NOW evacuation order.
An aerial photo from the Oregon Department of Transportation shows the top of the hill above the Siletz River where Friday morning’s landside began before hitting residential properties below and ending up in the river.
Massive landslide Friday closes Highway 229 between Siletz and Kernville, damaging homes and sending debris into river:

This is what a vibrating saguaro sounds like (sped up ambient vibration with coeval ambient audio): geohazards.earth.utah.edu/images/Sagua...
Saguaro cacti on a mountain side.
Resonance frequencies are in the range of 0.5-4 Hz, with damping ratios of 1-2%. Results describe material properties needed for hydrodynamic or other stability analyses, and come from purely nondestructive ambient seismic data.
Model simulation showing different bending modes of a saguaro stem.
Saguaros vibrate much like a cantilever, but with some interesting differences. Stiffness varies between cacti (taller stems are stiffer), and for a single stem (taller stems have softer tops).

This was an interesting study for me, something new:

Nice to be out measuring vibration of arches again

Millions of acres of our public lands could be available for sale under the Senate's version of the budget reconciliation bill.

240 m runup gives a minimum velocity estimate of 69 m/s!
Unfortunately no, it's an older photo :)
Still over here measuring vibration of stuff
Western voters overwhelmingly support keeping national monument protections in place, and ensuring Tribal Nations help lead the care of their sacred places.
→ 88% support monument protections
→ 83% of Republicans, 87% of Independents, 97% of Democrats
→ Even 4 in 5 MAGA voters agree

National monuments are hugely popular with Utah voters, yet here we go again with attacks on OUR public lands:

Nice!
Looks lovely!
I like it, and have another for you in the same spirit: Harvard Glacier in PWS AK, an oddball advancing glacier mowing down the forest on the fjord walls (larger background glacier obv!)
Whoa, fantastic super-elevation indiactors! When did it happen, known?

A helicopter for sure, and specifically a three-blade helicopter! The infrasound frequency is simply the number of blades times the revolution rate of the main rotor, and is typically around 20 Hz for three blade helicopters. Doppler shifted thereafter
