Radar interferogram from Sentinel-1 descending track 87, Apr 23 - May 5, 2018. Colors indicate line of sight displacements, positive toward the satellite. Apparent displacements associated with Mauna Loa and Mauna Kea, as well as near-coast areas at the NW and SW tips of the island are due to atmospheric artifacts. Blue star denotes the earthquake epicenter.
