GO-EUREKA Second Workshop (WS2) Wraps Up in Rome

The second GO-EUREKA workshop (WS2) has successfully wrapped up in Rome, Italy, held at Sapienza University over 23–24 June 2026. The workshop followed the Cassini Programme Day that opened the Rome 2026 event on 22 June.

The network came together to take stock of recent earthquake and tsunami events, push forward on near real-time ionospheric monitoring, and confront the challenges of distinguishing genuine co-seismic signals from background disturbances.

Workshop Program

The workshop was organized around three thematic sessions:

Session 1 — Lessons Learned from Recent Earthquake and Tsunami Events (Chair: M. Ravanelli)

• How the 29 July 2025 Mw 8.8 Kamchatka Earthquake Shook the Ionosphere over Japan — R. K. Barad et al.
• The Kamchatka Tsunami: Perspectives for Near Real-Time Ionospheric Monitoring — C. Maréchal et al.
• Invited presentation Simulation of Oceanic and Atmospheric Gravity Waves — Usama Kadri

Session 2 — Toward Near Real-Time Monitoring of Earthquakes and Tsunamis Using Ionospheric Observations (Chair: E. Astafyeva)

• Real-Time GNSS Data Sharing: Current Status and Perspectives — L. Rolland
• Data Collection, Processing, and Visualization Framework — M. Ravanelli
• Demonstrator for Earthquake and Tsunami Ionospheric Monitoring: Toward Operational Implementation within FormaTerre — G. Guérin, L. Rolland
• Disturbance detection algorithms, benchmark objectives, and DeepTEC/AIDE — E. Astafyeva, I. Ouar
• Benchmark discussion on detection speed, reliability, event discrimination, and operational constraints

Session 3 — Background Ionospheric Disturbances and Monitoring Challenges (Chair: L. Rolland)

• Ionospheric Disturbances Prior to Severe Weather: A Case Study over Brazil — H. Honda
• Selected Aspects from the IONO-DIET Project — E. Kherani
• Discussion: estimating environmental characteristics relevant for tsunami early warning from ionospheric observations

Looking Ahead

WS2 closed with a clear sense of direction: expanding real-time GNSS station coverage, advancing detection algorithms against a common benchmark, and building toward operational ionospheric monitoring for earthquake and tsunami early warning.

Thank you to all participants, presenters, and hosts who made WS2 a productive step forward for the network. Stay tuned for more updates as this work continues.
