Temporal Change in Resistivity Structure Before and After the 2018 Small Phreatic Eruption Iwo‐Yama Volcano, Kirishima Volcanic Complex, Japan

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract A small phreatic eruption occurred on April 2018 Iwo‐yama, Kirishima volcanic complex, Japan. We estimated the change in the subsurface resistivity structure before and after the phreatic eruption by repeated magnetotelluric (MT) measurements. A substantial decrease in resistivity was determined in the zone from the surface down to a depth of ...

Interseismic, Coseismic, and Early Postseismic Slip Associated With the 2025 Mw 8.8 Kamchatka Earthquake

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract Unraveling the surface deformation and fault kinematics during the seismic cycle is crucial for understanding earthquake physics. Herein, we use geodetic and seismic observations to quantify the interseismic coupling, coseismic rupture, and postseismic afterslip associated with the 2025 Mw 8.8 Kamchatka earthquake.

Monitoring Alpine Glaciers with ALOS SAR and Optical data [PDF]

, 2007
International audienceThe monitoring of temperate glacier activity is one of the applications which require the combined use of optical and SAR data. It should become feasible thanks to the ALOS PRISM and PALSAR sensors.

Multi‐Stage Shallow Rupture and Pre‐Event Shallow Deformation During the 2025 Mw 5.9 Asadabad Earthquake (Afghanistan)

Geophysical Research Letters, Volume 53, Issue 9, 16 May 2026.
Abstract The 31 August 2025 Mw 5.9 Asadabad earthquake in eastern Afghanistan caused severe damage despite its moderate magnitude, raising questions about rupture processes and seismic hazard in the southern Hindu Kush. Using Sentinel‐1 InSAR and teleseismic waveform modeling, we reveal a complex, multi‐stage shallow (4–5 km) rupture involving the ...

ESTIMATION OF ATMOSPHERIC EFFECTS OF RADARSAT-2 D-InSAR PRODUCT USING GROUNDBASEDAND SPACEBORNE METEROLOGICAL DATA [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences, 2015
Differential Interferometric synthetic aperture RADAR (D-InSAR) has emerged as one of the influential tools for the measurement of Earth’s topography deformation. The temporal variability of atmosphere plays a contaminative role in degrading the accuracy

Advanced D-InSAR techniques applied to a time series of airborne SAR data [PDF]

2007 IEEE International Geoscience and Remote Sensing Symposium, 2007
This paper presents airborne differential SAR results using a stack of 14 images, which were acquired by the experimental SAR (E-SAR) system of the German Aerospace Center during a time span of only two and a half hours. An advanced differential technique is used to retrieve the error in the digital elevation model and the temporal evolution of the ...

First TerraSAR-X interferometry evaluation [PDF]

, 2007
The German radar satellite TerraSAR-X was launched in June 2007 [1] and is currently ending its commissioning phase. We anticipate quite different interferometric application scenarios compared to ERS- 1/2 and ASAR due to the X-band frequency, the ...

Geomorphological mapping of the Becca d'Aver deep‐seated gravitational slope deformation (Aosta Valley, Italy) based on multi‐scale and multi‐sensor analysis

Earth Surface Processes and Landforms, Volume 51, Issue 5, May 2026.
Geomorphological characterization of the DsGSD enables us to identify the sources of sediment that could be mobilized as debris flows. In the area, pseudo‐badlands morphotype has been defined and mapped, representing the main sources of risk beside abandoned quarry deposits.

Estimation of the fault geometry of the Median Tectonic Line (MTL) in Eastern Shikoku, Southwestern Japan, via GNSS and InSAR time series analysis

Earth, Planets and Space
The Median Tectonic Line (MTL) is one of the largest active fault systems in Japan. Whether the active MTL fault is north-dipping or near-vertical is still under debate.
