The dam upstream: why flood warnings fail the White Volta Basin and what we can do about it

Map of Ghana and Burkina Faso showing the White Volta Basin in light blue, a green validation domain, and the locations of a dam and a gauge. An inset map shows the region's location in West Africa.

On 25 August 2025, SONABEL – Burkina Faso’s national utility – began releasing water from the Bagre Dam two days ahead of schedule. The reservoir had reached 90% of its capacity, just 0.73 metres below its maximum retention limit [9]. The Water Resources Commission and the National Disaster Management Organization (NADMO) in Ghana issued immediate …[Read More]

From Seismic Signals to Safer Trains: Italy’s First Earthquake Early Warning System for High-Speed Railways

Earthquakes remain among the most disruptive natural hazards worldwide, capable of causing sudden loss of life, severe economic damage, and long-lasting societal impacts. One of the most effective tools developed in recent decades to mitigate these effects is Earthquake Early Warning (EEW), a real-time monitoring strategy that exploits a fundamental physical property of earthquakes: seismic …[Read More]

Advances in earthquakes forecasting pass through machine learning

Advances in earthquakes forecasting pass through machine learning

In today’s interview, we meet Dr Fabio Corbi, a researcher at IGAG-CNR, the Institute of Environmental Geology and Geoengineering of the Italian National Research Council. Fabio has experience in analogue modelling of megathrust earthquakes and he is currently exploring the potentiality of machine learning in this research field. Hi Fabio, would you briefly tell us …[Read More]

The earthquake traffic light

The earthquake traffic light

Dr. Laura Gulia is a senior post-doc at the University of Bologna, Department of Physics and Astronomy. She has a strong experience in statistical seismology, seismicity analysis as well as seismic hazard and risk assessment. Recently, she investigated the spatio-temporal evolution of the earthquake size distribution throughout a seismic sequence focusing on the b-value, a …[Read More]

Faults and earthquakes as friends and not foes

Faults and earthquakes as friends and not foes

The earthquakes’ occurrence on the planet Earth is largely considered synonymous with disasters and people generally perceive geological faults as a threat to life and belongings. However, there are exceptions since a small community of earthquake researchers relate the occurrence of earthquakes with the lithospheric plate interactions where movement on faults causes earthquakes. Therefore, my …[Read More]
