Ship‐Based GNSS Tsunami Detection: Pilot Network Demonstration
Journal of Geophysical Research: Oceans, Volume 131, Issue 9, September 2026.Abstract We demonstrate the potential for ship‐based GNSS systems to contribute to tsunami warning. We built a pilot network of 10 ships—8 commercial and 2 research vessels—equipped with a tsunami detection package consisting of a geodetic‐grade GNSS antenna and receiver, and satellite internet communications.

Seismic Constraints of the 23 November 2025 Hayli Gubbi Eruption Sequence in Afar, Ethiopia
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract On 23 November 2025, the Hayli Gubbi volcano in Afar (Ethiopia) erupted in a massive explosion. We present the first seismic characterization using data from 13 regional seismological stations. Seismograms reveal signals consisting of a minute‐long precursor, a main eruptive phase, and secondary events hours later.
