Applying InSAR to landslides and other stuff at the Geological Survey of Norway (NGU). Opinions here are my own, not necessarily my employer's.
Our thoughts about this are expanded in this paper, just released after the ISPRS meeting in Toronto. isprs-archives.copernicus.org/articles/XLI...
ISPRS-Archives - From InSAR Norway to a Global Ground Motion Service: Operational Monitoring for Disaster Risk Reduction

Just under two weeks left to submit abstracts to the 7th World Landslide Forum (WLF7), to be held in India in November 2026. I’d like to draw attention to a couple of #InSAR #DRR sessions that may be of interest: wlf7.org/themes-sessi...
Nice summary of our new #InSAR Svalbard service by the Norwegian Space Agency (in Norwegian). Still just five pilot areas but we are scaling up to the full territory over the next years. romdirektoratet.no/aktuelt/insa...

I have a joke about InSAR but it's only funny after unwrapping.

This is a big one, literally. New paper out in Geomorphology: we use multi-geometry Sentinel-1 InSAR to unravel the internal kinematic segmentation of a 55 km² deep-seated landslide in the NW Himalaya. www.sciencedirect.com/science/arti... #DRR #InSAR #Sentinel-1 #landslide
Hey #inuitart experts. I purchased this qiviut wall hanging in Yellowknife in 1993. It used to have a tag on it with the name of the artist, as well as the community she came from, but it is lost. I would very much like to know more about the artist. Does anyone recognise the signature or the style?

Full of leading scientific institutions, Trondheim could be a natural laboratory for world-class collective transport. But progress remains constrained by car-centric policies that support electried, privately-owned cars. The thinking: Green cars = Green economic growth. A cosmetic solution.
On this International Day for Disaster Risk Reduction, iddrr.undrr.org, I'd like to call attention once again to our idea of an InSAR-based global ground motion service, and our upcoming special session at ISPRS in Toronto. Abstract deadline is Nov 3. www.isprs2026toronto.com/special-sess...
International Day for Disaster Risk Reduction (IDDRR)
Financing is the single challenge that unites the disaster, climate, development, and humanitarian domains. The unique advantage of disaster risk reduction is that it can simultaneously strengthen all the other domains, because of its emphasis on reducing vulnerabilities and building resilience.

CLICKBAIT VOICE We processed radar images... You won't believe how much the ground moved! HAIKU VOICE Silent satellites. Unwrapped phase reveals secrets. The land shifts unseen. CONSPIRACY VOICE Supposed "scientists" claim ground deformation, based on "interferograms" from secret radar images.

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-...
