Applying InSAR to landslides and other stuff at the Geological Survey of Norway (NGU). Opinions here are my own, not necessarily my employer's.

Hus evakueres etter leirras like ved containerskip pΓ₯ Byneset i Trondheim Like ved stedet lasteskipet traff land har det gΓ₯tt et 100 meter bredt leirskred.

And in related weird news, a quick clay slide was triggered near Trondheim, Norway, when a container ship ran aground next to a house! www.nrk.no/trondelag/hu...

We processed radar images...
You won't believe how much the ground moved!

Silent satellites.
Unwrapped phase reveals secrets.
The land shifts unseen.

CONSPIRACY VOICE
Supposed "scientists" claim ground deformation,
based on "interferograms" from secret radar images.

A proper tiramisu always starts with making a zabaglioni, to get a nice thick texture. I think the pasteurization is a secondary effect.

More than 10,000 scientists living, working or educated in Germany have already signed this appeal by @de.scientists4future.org to the members of the newly elected parliament to step up efforts for climate protection. Click here www.bayceer.uni-bayreuth.de/s4f/de/top/o... if you'd like to join.

PSLV NISAR (NASA-ISRO Synthetic Aperture Radar) GSLV Mk II Rocket Launch The NASA-ISRO Synthetic Aperture Radar, or NISAR satellite, will use advanced radar imaging to map the elevation of Earth's land and ice masses 4 to 6 times a month at resolutions of 5 to 10 meters. I...

Finally a predicted launch date for #NISAR (May 20). It will be a relief to see this happen, given the current political and financial chaos. I just hope the ground segment funding remains in place. www.spacelaunchschedule.com/launch/gslv-...

I'm pretty sure that 1 of those 9 will be rescinded very soon ☹️.

This will just bring us back to where we were a couple of years ago, with new images every 6 days instead of 12. But we also need to get the 1D satellite up ASAP to be truly secure because 1A is on its least legs now.
