The surviving house in Pacific Palisades became one of the most discussed images from the 2025 California wildfires (Fig. 1). What makes it scientifically interesting, though, is not that it survived. It is that many of the features associated with the house’s survival – a more fire-resistant exterior, stronger windows, and details that reduce ember entry – are already well known. This case points ...[Read More]
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 quiet assumption buil ...[Read More]
As natural hazard scientists, we often emphasise the concept of exposure – how much people, infrastructure, and ecosystems are in harm’s way when close to natural hazard sources (e.g., floodplains, volcanoes, or fault lines). The closer you are, the higher the risk. Therefore, one of the main goals in natural risk assessment is to reduce exposure whenever possible. We advocate for informed plannin ...[Read More]
Coastal regions have always been at risk from natural hazards, but now, there’s an added layer of complexity. Earthquakes, which cause the land to move up or down, can significantly affect sea levels, especially in regions already experiencing the effects of climate change. Earthquakes can alter coastlines in ways that we’re still trying to understand, and it’s clear that tectonically active areas ...[Read More]
In the morning of May 28, 2025, the picturesque Swiss alpine village of Blatten sat quiet and serene in the Lötschen Valley. Exceptionally quiet, in fact, as the village was evacuated on May 19th after a local Natural Hazards expert spotted a worrisome change in a local mountain looming about the village, the Kleines Nesthorn: it was collapsing faster. The Kleines Nesthorn is a 3,341-meter peak wi ...[Read More]
This week I think back on my time in the United States of America, where I was able to spend the holiday season. In North America, “fall” marks the beginning of this holiday season, and symbolises a time filled with traditions of togetherness that transcends regions. In New England, particularly in the state of Massachusetts, the season is synonymous with crisp air, vibrant foliage, and the celebr ...[Read More]

The EGU 2025 General Assembly, scheduled from 27 April to 2 May 2025 in Vienna, Austria, is one of the most anticipated events in the geosciences field. This year’s assembly is expected to gather thousands of scientists from across the globe, offering an unparalleled opportunity to engage with the latest research, innovations, and trends in Earth, planetary, and space sciences. Whether you’re a st ...[Read More]
Multi-hazards are “a selection of major hazards that a country faces, and specific contexts where hazards occur simultaneously, cascadingly, and accumulatively considering the interrelationships among them”, based on the UNSDRR definition [7]. Yet, this definition raises two key questions: Where are these specific contexts located, and what characteristics make them susceptible to intersecting haz ...[Read More]
When another year comes to an end, it is time for reflection. In the context of natural hazards, it is essential to consider the challenges posed to societies, what went well, what could have been done better, and how we could create a more resilient world. Just before Big Ben strikes 12 times, marking the moment of a new day and year, and the fireworks are set to begin, our blog editors share th ...[Read More]
