Ground motion from space (virtual)

Monitoring ground motion is critical to mitigate related hazards. How to measure it precisely for large scale? SAR interferometry (InSAR) allows measuring large scale land motion with unprecedented spatial resolution and accuracy from space.
The talk is about: (1) to understand of the capabilities of the InSAR for measuring the ground subsidence; (2) to demonstrate examples in Hanoi, HCMC and the Mekong; (3) to highlight the implication on a new Vietnam X-band SAR mission (JV-LOTUSat) (2023).
