Operational monitoring of our hazardous planet with Sentinel-1 Open
The European Commissions Sentinel-1 constellation, operated by ESA, has been a game changer for operational monitoring of our hazardous planet. When fully operational, the Sentinel-1 mission is a two-satellite constellation; currently cons…
LiCSAR: An Automatic InSAR Tool for Measuring and Monitoring Tectonic and Volcanic Activity Open
Space-borne Synthetic Aperture Radar (SAR) Interferometry (InSAR) is now a key geophysical tool for surface deformation studies. The European Commission’s Sentinel-1 Constellation began acquiring data systematically in late 2014. The data,…
High‐Resolution Surface Velocities and Strain for Anatolia From Sentinel‐1 InSAR and GNSS Data Open
Measurements of present‐day surface deformation are essential for the assessment of long‐term seismic hazard. The European Space Agency's Sentinel‐1 satellites enable global, high‐resolution observation of crustal motion from Interferometr…
Explosive Eruptions With Little Warning: Experimental Petrology and Volcano Monitoring Observations From the 2014 Eruption of Kelud, Indonesia Open
Explosive eruptions that occur with little or no precursory unrest (less than a month) pose the greatest hazards from volcanoes to nearby populations. Here we focus on the preeruptive conditions for these explosive events, their triggers a…
A New Method for Large-Scale Landslide Classification from Satellite Radar Open
Following a large continental earthquake, information on the spatial distribution of triggered landslides is required as quickly as possible for use in emergency response coordination. Synthetic Aperture Radar (SAR) methods have the potent…
Integration of SAR Data Into Monitoring of the 2014–2015 Holuhraun Eruption, Iceland: Contribution of the Icelandic Volcanoes Supersite and the FutureVolc Projects Open
We report how data from satellite and aerial synthetic aperture radar (SAR) observations were integrated into monitoring of the 2014–2015 Holuhraun eruption in the Bárðarbunga volcanic system, the largest effusive eruption in Iceland since…
Insights Into the Stress Field Around Bárarbunga Volcano From the 2014/2015 Holuhraun Rifting Event Open
The two weeklong rifting event at Bárðarbunga volcano in 2014 led to the Holuhraun eruption, which produced 1.5 km 3 of lava and was the largest in Iceland in over 200 years. Predicting when and where an intrusion will lead to eruption req…

Gradual caldera collapse at Bárdarbunga volcano, Iceland, regulated by lateral magma outflow Open
Driven to collapse Volcanic eruptions occur frequently, but only rarely are they large enough to cause the top of the mountain to collapse and form a caldera. Gudmundsson et al. used a variety of geophysical tools to monitor the caldera fo…
InSAR processing for volcano monitoring and other near‐real time applications Open
Radar interferometry (InSAR, interferometric synthetic aperture radar) is routinely used to measure surface deformation prior to, during, and after volcanic events, although not in a monitoring capacity. The improved data availability of s…
Concept of an Effective Sentinel-1 Satellite SAR Interferometry System Open
This brief study introduces a partially working concept being developed at IT4Innovations supercomputer (HPC) facility. This concept consists of several modules that form a whole body of an efficient system for observation of terrain or ob…
