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.

Very‐Long‐Period Seismic Signals During Lateral Dike Propagation at Piton de La Fournaise Volcano

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract We report a previously undocumented sequence of very long period (VLP) signals preceding the September 2022 eruption at Piton de la Fournaise. These events occurred during lateral magma propagation and exhibit quasi‐periodic sawtooth‐shaped displacement transients.

Economic loss estimation for earthquake hazard in Istanbul [PDF]

Natural hazards, especially earthquakes, cause disasters when they hit large settlements such as metropolitan areas. After the first shock, the damage is counted by deaths and injuries.
