Data for: Satellite Geodesy Uncovers Fifteen Meters of Slip on a Detachment Fault Prior to the 2018 Collapse at Anak Krakatau, Indonesia

On December 22, 2018, a catastrophic collapse occurred in the Anak Krakatau volcano, triggering a deadly tsunami. To investigate surface displacements leading up to the collapse, we analyzed Interferometric Synthetic Aperture Radar (InSAR) satellite geodetic data from 2006 to 2018. We identified the line-of-sight displacements on the southwestern flank of the volcano throughout the entire study period. By analyzing data from different satellites (ALOS-1, COSMO-SkyMED, and Sentinel-1), we found that the detachment fault experienced approximately 15 meters of slip from 2006 to 2018 before the collapse. Specifically, the COSMO-SkyMED data revealed a rectangular dislocation with a cumulative slip of 12 meters from April 2012 to December 2018. The slip rates varied during different time periods, ranging from 1.2 to 3.1 meters per year based on the fault geometry. Additionally, ALOS-1 and Sentinel-1 data provided slip estimates of 0.88 meters per year and 1.1 meters per year, respectively.
