The Alaska Earthquake Center is expanding its real-time monitoring network of 150 stations by adding 43 stations first installed as part of the USArray project. Expansion regions were chosen to improve the speed and accuracy of earthquake reporting in southeast Alaska, and to lay a foundation for earthquake early warning in the state's populous and seismically hazardous south-central region. Within those regions, existing USArray stations were chosen based on location and accessibility, data quality, and telemetry method. We will present a summary of our operation and maintenance strategy as it relates to each of these categories and highlight challenges we have encountered that may be relevant to other network operators planning expansions.
