Presentation Time: 11:30 AM Pacific

Description: 

Alaska Volcano Observatory (AVO) maintains a network of 194 seismometers deployed on active volcanoes across the state. Real-time data from these instruments are acquired at the AVO facility in Anchorage, Alaska and routinely processed to better understand current activity and hazards at volcanoes in Alaska.

While tools have been developed which enable Observatory staff to access data and remain productive when they're unable to work in their office, the seismic processing system itself has remained dependent on the AVO Anchorage facility. This dependence has been driven by factors including the difficulty of establishing redundant long-haul telemetry paths and the costs of maintaining a remote processing facility. Expanded networking options and the availability of low-cost cloud services present an opportunity to begin eliminating AVO's dependence on the Anchorage facility. This first step provides redundant Earthworm acquisition capability, giving network architects a second endpoint to use while planning alternate data paths from the field, and application developers a second source for seismic data. Individual stations are grouped by network configuration and acquired concurrently at both acquisition nodes when possible. Where concurrent acquisition is not possible due to available bandwidth or routing limitations, the acquiring node forwards the data to its partner node. Through this configuration, both nodes are able to receive and serve all available data. As field networks are expanded and upgraded to modern instrumentation and telemetry, individual imports can easily be modified to take advantage of those improvements, fully leveraging the available data.
