Service Description: Satellite synthetic aperture radar interferometry (InSAR) shows dike opening in the far eastern ERZ. The interferogram observations capture the total displacement between May 8, 2018 and May 22, 2018. Other observations: seismicity, and InSAR and GPS geodetic data, suggests that most of this motion is related to the ongoing fissure eruption that started on May 3, 2018. Each color cycle is approximately 12 cm and is the projection of surface displacements into the radar line-of sight. Included in this interferogram are noise signals due to tropospheric and ionospheric atmosphere residuals. Also, a ramp in the along-track direction was removed from this interferogram. The interferogram was produced by the ARIA project which is a joint effort of NASA's Jet Propulsion Laboratory and the California Institute of Technology using synthetic aperture radar (SAR) data from the Japanese Aerospace Exploration Agency's (JAXA) PALSAR-2 L-band radar on the ALOS-2 satellite. ALOS-2 SLC data provided through RA6 AO project number P3024002. ALOS-2 processing used ISCE software processing components. Part of this research was carried out at the Jet Propulsion Laboratory, California Institute of Technology, under a contract with the National Aeronautics and Space Administration.
