Published in #GJI: "Resolving blind mid-crustal earthquake deformation with InSAR time-series: the 2021 Mw 6.4 San Juan earthquake and implications for a non-optimal fault reactivation in the Andean Fold and Thrust Belt, Argentina", León-Ibáñez & Delgado academic.oup.com/gji/article/...
Study area overlaid on SRTM topography (Farr et al. 2007). Focal mechanisms of major historical earthquakes are shown: 1944, 1952 (Alvarado & Beck 2006), 1977 (Ekström et al. 2012) and 2021 (marked as a star) (Ammirati et al. 2022). Framed areas indicate SAR data acquisition. Faults are simplified from Costa et al. (2020) and Styron & Pagani (2020). El Tigre dextral fault is highlighted in red. Yellow dots mark earthquakes with magnitudes > 4.5 since 1950 in the upper 60 km of the crust, red dots mark aftershocks within the first 2 weeks after the earthquake with a mb 5.3 maximum magnitude (United States Geological Survey 2024). Diamonds and corresponding labels mark the location of nearby permanent GNSS stations (Nevada Geodetic Laboratory 2024). White triangles represent the cities of San Juan (north) and Mendoza (south). Dashed line denotes the Chile-Argentina border.

JPL imaging tech (InSAR interferometry) could detect mm-scale strain transients. This will lead to an operational earthquake prediction system - seismology must shift to physics. https://www.cnn.com/2010/TECH/space/06/30/nasa.earthquakes/index.html

The source for my InSAR training if from the good folks at Alaska.edu and their ASF team.

Seeing how they are dismantling Nasa breaks my heart to smithereens.

I have a mad respect for that crew and I sure hope that every single person behind this dismantling gets to go to jail or worse.

ok, after a couple of days churning InSAR data from Minas Gerais, Brazil from Oct, 2015 through Jan, 2020 the findings will haunt me for some months now.
i had to double check all RMS values, Coherence error verification are all good. I did not perform atmospheric correction due an issue.

But it will come around.
InSAR allows you to measure soil displacement at the centimeter scale, works pretty well in flat lands and it has natural limitations in hilly areas.
SO in order to map what happened in Mariana, i made some mistakes till i got it right...

actually no, sorry i lied

I have clients in the region and it was devastating in ways that very few recovered from it.
So I started to study every piece of tech to help me measure and understand how these things come to be.
The hardest tool, and my latest learning project is InSAR.
And I can't differentiate it from magic yet

🚨 New paper Alert! 🌋🛰️

We report the first signs of unrest at #Taftan Volcano (Makran Arc). Using InSAR and Common-Mode Filtering method, we detected a spontaneous 10-month summit uplift—without any external trigger—suggesting possible internal magmatic processes.

🇮🇸 🌋 Reykjanes - Svartsengi 🟨

I've been here since November 10, 2024, and I've fully started posting about the 6th eruption ( November 20, 2024 ).

I was just thinking about the next eruption - and it occurred to me that I have many new, lovely followers ...

2023 Updated October 28 at: 1:30 PM The latest GPS data and InSAR satellite imagery from yesterday afternoon show clear signs of land uplift near Svartsengi. Land uplift appears to have started yesterday, October 27, and indicates increased pressure, most likely due to magma intrusion at depth. The center of the land uplift is about 1.5 km northwest of Þorbjörn, near the Blue Lagoon. In 2020 and 2022, land uplift was also measured in the same area. This is the fifth time since 2020 that land uplift has been measured there. The initial assessment of the current rate of land uplift is that it is faster than before. At present, there is no sign of magma moving closer to the surface, but conditions may change in a short time. Fracture movements due to trigger earthquakes near and east of Svartsengi could potentially allow magma to move shallower in the crust. The latest deformation data from the Reykjanes Peninsula show that a multifaceted process of magmatic movement is underway in the Earth's crust. These processes affect a large area, including Fagradalsfjall (where expansion continues - since August 2023), the area east of Festarfjall (where deformation appears to have stopped) and in the last 24 hours data show land rise near Svartsengi. Over 7000 earthquakes have been recorded in the earthquake swarm that began on October 25 north of Grindavík. The swarm is still ongoing, although the activity has slightly decreased. Despite this, there is still a possibility of earthquakes in the area. Model calculations will be performed today to try to estimate the depth and size of the intrusion northwest of Þorbjörn. New satellite data will be available tomorrow evening and interpreted early Monday (October 30). This data should provide additional insight into magma movements and deformation on the Reykjanes Peninsula. Deformation from 26 Oct 2023 at 05:21 UTC to 28 Oct 2023 at 05:21 UTC. Satellite data obtained in collaboration with ICEYE ( https://www.iceye.com/ ).

You are correct that the seismicity is not on the north-dipping fault that borders the south side of the valley. The InSAR shows that the mountains south of the valley subsided in the first earthquake. There is another fault that dips south that is another possible candidate.
