Description: 

Monitoring of volcanoes in real-time has increased over the past decade as data transmission and cyberinfrastructure capabilities evolve. Since 2016, the multinational GNSS network TZVOLCANO was initiated to (1) improve our understanding of volcano-tectonic interactions during continental rift initiation at a range of temporal scales and (2) provide volcano deformation monitoring capabilities for local constituents. The TZVOLCANO network consists of 5 continuous GNSS stations with 3 streaming 1 second 4 cm precision positions and 1 co-located compact broadband seismometer. Here, we describe our implementation of the EarthCube cyberinfrastructure CHORDS (Cloud-Hosted Real-Time Data Services for the Geosciences) that we use to evaluate real-time streaming positioning data available through UNAVCO real-time data services, send email alerts for vertical velocities exceeding thresholds, and provide information about GNSS station health. In conclusion, we make available the simple brokering code that connects UNAVCO real-time services with CHORDS such that additional users of real-time GNSS can easily stream data into a CHORDS portal and build their own additional capabilities via its simplified interface.
