Information provided below are generated automatically by computers and were not validated a posteriori by a scientific analysis. Results are issued from a complex and unsupervised processing. Consequently they may be inaccurate or even erroneous. In particular, solution computed for the most recent dates are potentially less robust.

NOTE: The processing automatically rejects the interferometric pairs affected by low coherence measured at Laguna del Maule region (LdM).
It results that several images may not contribute to time series, typically during the Austral Winter.
Linear ground deformation rate in Domuyo region
Amplitude image in Domuyo region
Time series "double differential displacement analysis"
Measurement of displacement between 2 points: The time series graphics are available for horizontal (East-West), vertical (Up-down) and line of sight (ascending and descending) displacement.
The pairs of points are located around the Laguna Del Maule and Domuyo volcanoes areas, other measurement are in the Others area.
The buttons above each maps allow to switch between different view: S1 for Sentinel 1 amplitude view,
Maps for reliefs view and Earth for satellite view.
Wrapped phase displayed on SAR amplitude image and masked by the coherence.
