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

Aldo Zollo December 8, 2025

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]

If a Resilient City Had a Face: It Might Look Like Kagoshima

Hedieh Soltanpour August 4, 2025

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 …[Read More]

A look into the life of a volcanologist in Japan, one of the most hazardous countries for volcanoes

Shreya Arora December 7, 2020

In this interview, I talk with Chris Conway about his experience as a volcanologist in Japan, which is one of the countries with the highest volcanic threat in the world. You will read how studying crystals found within erupted lava flows can help hazard mitigation at active volcanoes and how volcanic hazard is managed in …[Read More]

DE BELLO VULCANICO 40-year scientific effort of ‘predicting the unpredictable’ since the 1980 eruption of Mount Saint Helens

Mattia Pistone July 6, 2020

Volcanoes arouse emotions in the soul of men: at the same time, they are fascinating and frighten the population that lives on their slopes when they erupt (Fig. 1). Volcanoes can strike without warning and wreak horrific destruction and death. As such, in the ancient time, volcanoes discharging explosive eruptions have been interpreted as the …[Read More]

The bad, the good and the unpredictable: living with volcanoes / part 1

Jazmin Scarlett October 28, 2019

Introduction Humans have existed and lived alongside volcanoes for as long as we have been on the planet. For some, this has been beneficial and often, in fact, we can see how indigenous knowledge finds a sustainable approach living with them. However, in some cases, societies cannot cope and are overwhelmed with volcanic eruptions. There …[Read More]
