Monitoring the soil after seismic activity is fundamental to understand the small but significant modifications on the soil. Thanks to the merge of satellite imagery and computing is possible to do it automatically nowadays. The Copernicus Sentinel-1 twin radar satellite takes consecutive pictures of the same place and the imagery is then combined with cloud computing to unveil millimeter variations.
This well-known practice was developed in the 80’s using GPS centimeter measurements.
The EDO pages contain drought-relevant information such as maps of indicators derived from different data sources (e.g., precipitation measurements, satellite measurements, modelled soil moisture content).
