The climate on our home planet is changing, and the effects of this change affect all of us at different levels starting from an enhancement of extreme weather events, a severe natural hazard. Climate change has several drivers, which in turn have complex interactions. Thus, it should not surprise us if climate science is a complex and interdisciplinary discipline with numerous players and great p ...[Read More]
Natural hazards that impact industrial sites and result in technological accidents, causing the release of hazardous substances, are referred to as Natech events. In the popular imagination, Natech accidents are triggered by major natural hazard events. However, experience tells us that low magnitude natural events, such as lightning or heavy rains, are sufficient to cause enormous adverse effects ...[Read More]
The frequency and intensity of drought periods have increased since the 1950s over most land areas [1]. In fact, between 1998 and 2017, drought was the sixth natural hazard associated with disasters (4.8% of the total number of disasters) but the second in terms of the total number of affected people (33% of the total number of affected people), causing more than 21,000 deaths [2]. For example, in ...[Read More]
With the Natural Hazards 101 series, we mean to bring our readers closer to the terminology often used in the field of natural hazards, but that may not be so familiar. In the first episode of the series, we focused on the definition of hazard and natural hazard. We moved then to the concept of risk, which brought us to define exposure and vulnerability. Later on, we digested the disaster terminol ...[Read More]
Even though significant epidemics and pandemics have been recorded many times throughout human history, the Covid-19 pandemic demonstrated how vulnerable our societies still are. While the consequences of the pandemic are still ongoing, the global response so far can potentially offer some insights to support climate change response. Undoubtedly, the world is already experiencing a wide range of c ...[Read More]
For today’s interview, it gives me great pleasure to host Dr Manfred Stähli, who will tell us about a new initiative in the field of Landslide Early Warning Systems (LEWS), which is attracting the attention and participation of researchers from many countries. This initiative is called LandAware. Manfred is a senior scientist in mountain hydrology, slope stability and early warning systems a ...[Read More]
In summer 2020, extreme rainfall events dumped up to 320 mm of rain in a single day in the Baixada Santista metropolitan region, São Paulo state, breaking Brazil’s record for the biggest rainfall in a single event and demonstrating one of the greatest threats of climate change. The damage caused by the associated landslides led to dozens of fatalities and hundreds of homeless people, as well ...[Read More]
In the afternoon of August 29, 2020, an intense supercell, which is a thunderstorm characterized by the presence of a deep, persistently rotating updraft, affected the province of Verona in the north of Italy (Figure 1). It was not the first event of this kind; several other events, including tornado episodes, had already occurred during summer 2020. Here the video of the downburst recorded during ...[Read More]
When you read about climate extremes, what is the first thing that comes to your mind? Probably not airport systems. However, you might have been affected at least once by delays, longer flights, or even flight cancellations due to low visibility, strong winds, convective activity which can lead to thunderstorms. Especially, if you reside in or have flown to or from the United Kingdom, the Netherl ...[Read More]
