Welcome to the IRIS Image Gallery - a diverse collection of photographs and visuals that encompass the range and breadth of seismology and the seismological community.
Please browse through our albums. These low and medium-resolution images can be freely used for personal and educational/academic purposes, but we request you recognize the image contributor by including in your product or presentation the credit displayed with each image.
The upgrade of the GSN is underway with the Next Generation systems (NGS) being deployed at all stations. This album shows photos from the upgrade work.
The upgrade uses a new GSN field system design developed jointly by the ASL and Project IDA based on the Quanterra Q330HR high-resolution data acquisition system. The NGS standardizes the stations of the GSN between the network operators, allowing more uniform installation, operation and maintenance techniques for the network. Rollout of the new systems across the entire GSN will take several years, but the design is now complete and the older obsolete, non-standard systems have a replacement.
