Penerapan Metode Permanent Scatterers Interferometry Synthetic Aperture Radar (PS-InSAR) untuk Analisis Deformasi Gunungapi (Studi Kasus : Gunungapi Sinabung)

Jurnal Teknik ITS, 2020
Di Indonesia terdapat 129 gunungapi yang masih aktif, salah satunya adalah Gunungapi Sinabung. Sepanjang tahun 2017 tercatat Gunungapi Sinabung mengalami erupsi-erupsi kecil akibat aktivitas magma. Pada gunungapi yang sedang aktif akan terjadi perubahan bentuk permukaan tanah yang disebut sebagai deformasi permukaan.

Damage Detection and Analysis of Urban Bridges Using Terrestrial Laser Scanning (TLS), Ground-Based Microwave Interferometry, and Permanent Scatterer Interferometry Synthetic Aperture Radar (PS-InSAR) [PDF]

Remote Sensing, 2019
This paper presents a practical framework for urban bridge damage detection and analysis by using three key techniques: terrestrial laser scanning (TLS), ground-based microwave interferometry, and permanent scatterer interferometry synthetic aperture radar (PS-InSAR). The proposed framework was tested on the Beishatan Bridge in Beijing, China. Firstly,

Pre- and post-failure dynamics of landslides in the Northern Apennines revealed by space-borne synthetic aperture radar interferometry (InSAR)

Geomorphology, 2020
Abstract Landslides are common landscape features in the Northern Apennine mountain chain and cause frequent damages to human structures and infrastructure. Most landslides in the area can be classified as earthflows, where the clay-shales form the substrate, whereas complex landslides with flow and sliding components are common on the slopes where ...
