SSA call for abstracts: New Possibilities for InSAR in Earthquake Science: the NISAR Mission and OPERA Displacement Maps

[Fielding, Eric J (US 329A)]

Dear Colleagues,

We request that you consider submitting an abstract to the SSA session call New Possibilities for InSAR in Earthquake Science: the NISAR Mission and OPERA Displacement Maps at the SSA Annual Meeting in Pasadena, California (April 14-18, 2026). Abstract submission is available at https://meetings.seismosoc.org/submit/ until the deadline of January 13th. We are excited to hear about new uses of the interferometric SAR observations now available from the OPERA Sentinel-1 Displacement data (DISP-S1) available for North America and from the NISAR mission that entered its science operations phase at the beginning of January 2026. First NISAR data, including systematic geocoded unwrapped interferograms,  will be released later this month.

Session details:

New Possibilities for InSAR in Earthquake Science: the NISAR Mission and OPERA Displacement Maps

In the past year we have seen two milestone advances in Interferometric Synthetic Aperture Radar (InSAR) measurements: the launch of the NASA-ISRO Synthetic Aperture Radar (NISAR) Mission and the release of the Observational Products for End-Users from Remote Sensing Analysis (OPERA) displacement maps over North America. NISAR launched successfully on July 30, 2025, and will begin distributing science data as early as mid-October 2025, ramping up to full science operations – collecting all land and ice-covered surfaces every 12 days from ascending and descending orbit vantage points - in early November 2025. These data will be freely and openly distributed from the NASA Alaska Satellite Facility (ASF) within days of acquisition. The OPERA project collects data from satellite radar and optical instruments to generate a variety of products, among them maps of line-of-sight (LOS) displacement over North America for existing InSAR missions, which will likewise be distributed by ASF. NISAR observations and OPERA displacement products are capable of addressing fundamental and applied research topics in earthquake science, including global tectonics, the impact of anthropogenic processes on active faults, and disaster response. This session invites contributions from those who plan to dive into these new data sets, showcasing early results.

Dear OPERA folks,

Katia and I are convening a special session called New Possibilities for InSAR in Earthquake Science: the NISAR Mission and OPERA Displacement Maps at the SSA Annual Meeting in Pasadena, California (April 14-18, 2026). We hope that some OPERA folks will consider submitting an abstract. Abstract submission is available at https://meetings.seismosoc.org/submit/ until the deadline of January 13th (tomorrow). We are excited to hear about new uses of the interferometric SAR observations available from the OPERA Sentinel-1 Displacement data (DISP-S1) available for North America now. We are also looking for science planned with data from the NISAR mission that entered its science operations phase at the beginning of January 2026.
