The European Union's Copernicus Sentinel-1 satellites, together with the COSMO-SkyMed constellation, provided important data related to the 2017 Ischia earthquake.

A magnitude 6.6 earthquake occurred in the Aegean Sea on 20 July 2017, affecting the Greek island of Kos and Bodrum in south-west Turkey. Images from the Copernicus Sentinel-1 mission were used to map the ground deformation, providing valuable data for analysis.

Satellite radar scans of last year's earthquake in New Zealand are changing the way we are thinking about earthquake hazards in regions where our planet's tectonic plates meet.

New information on the effects of the 30 October earthquake that struck central Italy continues to emerge as scientists analyse radar scans from satellites.

The Copernicus Sentinel-1 twin radar satellites combined with cloud computing are monitoring Europe's earthquake zones by searching for ground shifts as small as a millimetre.

As hundreds flee lava and ash spewed from Mexico's Colima volcano, its continuing eruption is being tracked not only by ground instruments but also from space. Starting last month, Colima is one of 22 active volcanoes worldwide being monitored by satellites.

On 24 August, an earthquake struck central Italy, claiming at least 290 lives and causing widespread damage. Satellite images are being used to help emergency aid organisations, while scientists have begun to analyse ground movement.

On 25 April, a 7.8-magnitude earthquake struck Nepal, claiming over 5000 lives and affecting millions of people. Satellite images are being used to support emergency aid organisations, while geo-scientists are using satellite measurements to analyse the effects of the earthquake on the land.

A Red Alert has been declared in southern Chile after the eruption of the Villarrica volcano early on 3 March. Thousands of residents in the area have been evacuated and the International Charter Space & Major Disasters has been activated by Chile's risk management authority ONEMI.

On 23 November 2014, an eruption started on Fogo Volcano (Cape Verde), almost 20 years from the previous one. 

Radar images from the Sentinel-1A satellite are helping to monitor ground movements of the recently erupted Fogo volcano.

Sentinel-1A has added yet another string to its bow. Radar images from this fledgling satellite have been used to map the rupture caused by the biggest earthquake that has shaken northern California in 25 years.

Imaging Earth's land with unprecedented speed and resolution has come another step closer as the next Sentinel satellite has been given its solar wing and started a strenuous six-month test campaign to make sure that it is fit for launch next April.

Calling all app developers: register today for the opportunity to spend a week at ESA developing new ideas and concepts for mobile apps using satellite Earth observation data.

From climate change monitoring to supporting humanitarian aid and crisis situations, early data applications from the month-old Sentinel-1A satellite show how the radar mission's critical observations can be used to keep us and our planet safe.

A large volcanic OClO and BrO plume could be tracked from ENVISAT SCIAMACHY jointly with EOS Aura MLS and OMI observations for 5 days after the June 2011 eruption of Puyehue-Cordón Caulle (PCC).

Sentinel-1A, Europe's first satellite for Copernicus, is almost ready for launch on 3 April. Meanwhile, ESA is showing how its advanced radar will map ice, monitor subsidence and much more.

In this study the scientists use Envisast ASAR data to investigate coseismic and post-seismic surface deformation associated with the 2008 Mw 6.3 Damxung earthquake on the Tibetan Plateau.

In this study the team combined time-dependent gravity and DinSAR ground deformation measurements demonstrating that are complementary to each other and their regular recording may disclose and clarify complex volcanic dynamics.

The Santorini caldera has been a source of numerous eruptions and tsunamis in the past with the most recent seismic sequence ending in 1950 .Since then, Santorini volcano was in a "quiet" phase, with insignificant deformation and limited seismic activity.
