[SCG68-P03] The EarthScope Plate Boundary Observatory and allied networks as a platform for seismo-geodetic integration to support Earthquake and Tsunami Early Warning Systems across the Americas

While progress has been made toward more open and free data access across national borders and toward more cooperation among cognizant government sanctioned “early warning” agencies, some impediments remain making a truly operational system a work in progress. Combining existing data sets and user communities, for example seismic and tide gauge observations with GNSS and meteorological data products, has proven complicated because of issues related to metadata, appropriate data formats, data quality assessment in real-time and other issues related to using these products operational forecasting.
UNAVCO has embarked on significant improvements to the original infrastructure and scope of our networks. We anticipate that the Plate Boundary Observatory (PBO) and related networks will form a backbone for these efforts with high quality, low latency raw and processed GNSS data as well as providing a platform for integration with other sensors, including broadband and strong motion seismometers. Low-cost MEMS accelerometers already have been deployed at 22 PBO stations in two clusters in California. Other additional and substantial upgrades are required across these networks, however, starting with upgrading the GNSS receiver, through robust data collection, archiving and open distribution mechanisms, to efficient data-processing strategies. UNAVCO is currently in a partnership with the stakeholders to define, develop, and deploy all segments of this improved geodetic network. We present the overarching goals together with current and planned future state of this international resource.
