IMPROVED SOURCE IMAGING OF THE KLEIFARVATN EARTHQUAKE, ICELAND, THROUGH A COMBINED USE OF ASCENDING AND DESCENDING INSAR DATA
We re-investigated the surface deformation of the Kleifarvatn earthquake on Reykjanes Peninsula, an event that was dynamically triggered by a moderatesize magnitude 6.5 earthquake 80 km away on 17 June 2000. Two ERS-2 interferograms from descending and ascending tracks were formed and used in combin...
