| Hanford has been storing nuclear waste in the ground for the past several decades and that is unlikely to change in the near future. From previous studies we know that ground deformation from seismicity can be detected using InSAR, however because of limited data availability I was unable to determine if deformation has continued since then. Historically seismic swarms have been a regular occurrence at various locations on the Hanford Site. Continued monitoring of seismic activity and ground deformation at the site is necessary to avoid hazardous waste leakage into the local aquifer within the Columbia River basalt layers. InSAR is a powerful tool that is finding more and more uses in scientific research. It has only been five years since the first geodetic measurements were made of a Hanford earthquake swarm. In the future, perhaps more data will become available for this region and a source of increased seismic activity and ground deformation can be determined. | Hanford has been storing nuclear waste in the ground for the past several decades and that is unlikely to change in the near future.
