How can we check if a simulated heatwave is plausible?

A white thermometer with a red liquid column stands in tan sand. The background shows a bright sun in a blue sky with light clouds.

Extreme heatwaves of unprecedented magnitude are expected to become increasingly frequent in coming decades. These heatwaves come with severe consequences for human health, infrastructure planning, and economic prospects – particularly during events lasting multiple weeks [10]. In recent decades, Western Europe has become a hot-spot for record-breaking and long-lasting heatwaves [9], raising a critical question: …[Read More]

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]

Post-Last Glacial Maximum intensification of marine faulting: resolution-dependent hazard assessment

Post-Last Glacial Maximum intensification of marine faulting: resolution-dependent hazard assessment

Subsea pipelines and cables are vital to modern energy and communications, yet assessing the active geological faults they cross underwater is notoriously difficult. By examining marine fault slip rates at higher stratigraphic resolution than previously analyzed in this region, our new research shows that displacement rates accelerated tenfold after the Last Glacial Maximum (LGM). This …[Read More]

When multiple hazards interact and the data doesn’t: The multi-hazard modelling problem nobody wants to talk about

There is a quiet contradiction at the heart of natural hazard science. The regions most exposed to multi-hazard events are precisely the regions where we know the least. The Global South (comprising lower- and middle-income countries in Africa, Asia, Latin America and the Caribbean) is disproportionately affected by climate-related natural hazards, yet it is largely …[Read More]

Same hills, different rules: why urban and rural landslides should not be considered together?

Same hills, different rules: why urban and rural landslides should not be considered together?

Cities are expanding faster than ever, often onto steep and unstable terrain. As urban areas grow, landslides increasingly threaten homes, roads, and critical infrastructure. To manage this risk, scientists produce landslide susceptibility maps, which estimate where landslides are most likely to occur. These maps are widely used by planners and decision-makers. But there is a …[Read More]

Living with a restless giant: The challenge of multi-risk management and communication at Campi Flegrei Volcano

Living with a restless giant: The challenge of multi-risk management and communication at Campi Flegrei Volcano

Nestled within one of Europe’s most densely populated regions, the Campi Flegrei caldera is a volcanic system whose secular unrest shapes the daily life of its inhabitants. Here, during the last decade and still ongoing crisis, ground uplift, frequent earthquakes, and persistent gas emissions interact to create a complex, evolving multi-risk environment. These natural hazards …[Read More]
