| Release Notes: | These continuous sites were built after the 2020 Simeonof earthquake, to study postseismic deformation from that event (and any potential future nearby events). Three sites were installed in August 2021 and recorded on site until June 2022, and were then upgraded to have Iridium telemetry so that daily data could be available. The other three sites were installed in June 2022. Graduate students at MSU and UAF are working on these data for their dissertation research. The sites are expected to operate until summer 2025, when permit conditions will require their removal. We thank the Alaska Maritime National Wildlife Refuge for allowing the installation of these sites. All sites are located adjacent to campaign markers with a long (1993-2021) measurement history, and the last campaign occupation was made at the time of installation of the continuous sites: ANDC – AND2 KUPR – no campaign site LKON – LITT BKON – INSU NGNE – WEDG NGSW – MOUN References for the campaign site velocities are: Li and Freymueller (2018) Elliott and Freymueller (2020) Drooff and Freymueller (2021) References for coseismic displacements and rupture model: Xiao et al.
