An Investigation of Volcanic Ground Deformation Using InSAR Observations at Tendürek Volcano (Turkey)

Applied Sciences, 2023
Although approximately one-tenth of the world’s population lives near volcanoes, most of the 1500 active volcanoes are not monitored by ground-based instruments because of the cost and difficulty of access.

GACO – A HYBRID ANT COLONY OPTIMIZATION METAHEURISTIC FOR THE DYNAMIC LOAD-BALANCED CLUSTERING PROBLEM IN AD HOC NETWORKS

Applied Artificial Intelligence, 2009
We present the design of a novel hybrid genetic ant colony optimization (GACO) metaheuristic. Genetic ant colony optimization is designed to address the dynamic load-balanced clustering problem formulated from ad hoc networks. The main algorithm in GACO is ACO.

Multi-sensor remote sensing analysis of coal fire induced land subsidence in Jharia Coalfields, Jharkhand, India

International Journal of Applied Earth Observations and Geoinformation, 2021
The subsidence in coal mines induced by surface and subsurface fires leading to roof collapse, infrastructure loss, and loss of lives is a prominent concern. In the study, satellite imagery from thermal and microwave remote sensing data is used to deduce

Independent Component Analysis (ICA) as a Superior Atmospheric Correction Method for InSAR Time Series

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 8, August 2026.
Abstract Satellites such as the European Space Agency's Sentinel‐1 constellation allow for the creation of unprecedented volumes of Interferometric Synthetic Aperture RaDAR data that contains both deformation and atmospheric signals. Correction methods have been developed to reduce these atmospheric signals, but they do not generally perform well on ...

Transient Creep on the Yarlung Zangbo Suture in Southern Tibet Triggered by the 2015 Gorkha (Nepal) Earthquake

Geophysical Research Letters, Volume 53, Issue 13, 16 July 2026.
Abstract Large earthquakes often elevate seismicity in surrounding regions, as seen on the Xainza‐Dinggyê rift in southern Tibet after the 2015 MW 7.8 Gorkha (Nepal) earthquake. In contrast, the EW‐trending Yarlung Zangbo suture (YZS), located directly north of this event, exhibits seismic quiescence.

Present-day land subsidence over Semarang revealed by time series InSAR new small baseline subset technique

International Journal of Applied Earth Observations and Geoinformation, 2023
Over the last two decades, Semarang, located in the central region of Java island, Indonesia, has been undergoing significant land subsidence. Mainly attributed to reservoir compaction and fluid extraction, this subsidence has pronounced effects in ...

Geodetic Constraints on Fault Kinematics and Dynamics of 2021 Maduo Earthquake: Implications for Fault Friction

Journal of Geophysical Research: Solid Earth, Volume 131, Issue 7, July 2026.
Abstract Postseismic afterslip has been inferred to occur on fault barriers surrounding coseismic asperities, which can be explained by velocity‐strengthening friction in barriers and velocity‐weakening friction in asperities. However, afterslip also exhibits spatial overlap with coseismic slip for some events.

Mitigation of tropospheric delay induced errors in TS-InSAR ground deformation monitoring

International Journal of Digital Earth
Interferometric Synthetic Aperture Radar (InSAR) is capable of detecting crust deformation. However, the accuracy is limited by spatiotemporal changes in the lower troposphere.

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 ...
