In the Netherlands, local authorities are looking to satellite observations as a promising option for dike monitoring and to protect against dike failures. In a recently completed Terrafirma study, the IJsselmeer dikes were checked using radar data from ESA's Envisat satellite for the period 2003–10.
This year, satellites saw the extent of Arctic sea ice hit a record low since measurements began in the 1970s. ESA's SMOS and CryoSat satellites are now taking a deeper look by measuring the volume of the sea-ice cover.
Archived radar data from the Envisat mission are playing an important role in mapping landslides in Switzerland. The mission’s vast archives continue to prove useful for mapping ground deformation. Landslides are a natural
Over the past year and a half, parts of the Greek Santorini islands have risen by 14 cm. Scientists believe that new molten rock has been squeezing up beneath a volcano accumulating in a magma chamber at a depth of about 4 km. Satellitedata confirm that the islands have risen as much as 14 cm since January 2011.
