Satellites Scan Glaciers for Mudslide Risks

Commercial satellites are providing critical oversight of glaciers upstream from Gyirong Port in China's Xizang autonomous region. Following a significant mudslide on August 26, Spacety's Synthetic Aperture Radar (SAR) satellites are now focused on monitoring ice surfaces for cracks and shifts that could indicate further hazards. This advanced monitoring system aids ongoing rescue operations by providing timely data.

The SAR technology's ability to penetrate clouds and operate at night, akin to 'CT scanners for the Earth,' is particularly advantageous in Gyirong's rugged mountainous environment. Interferometric SAR (InSAR) is also being utilized to detect ground deformation with millimeter-level precision, covering large areas efficiently without ground equipment. This integration of space and ground-based information creates a multi-layered monitoring network.

Spacety deployed its satellites rapidly after the mudslide, adjusting imaging plans within 20 minutes of a request. Initial SAR images captured on August 27 and 28 helped identify two barrier lakes, assessing downstream flood risks. Additionally, the satellites have documented damage to National Highway G216, aiding road clearing efforts. With multiple satellites offering varied perspectives, a comprehensive view of the evolving situation is maintained for rescue teams.
