A.
Optical Imaging
B.
Synthetic Aperture Radar (SAR) Interferometry
AnswerC.
Thermal Imaging
D.
Multispectral Imaging
Answer: Option B
Solution
Answer: Option B
Solution:
SAR Interferometry (InSAR) measures ground deformation by comparing radar images over time.It is highly effective for landslide monitoring and earthquake displacement.
