Aggravated by the effects of climate change, several extreme natural events have recently caused extensive damage to some UNESCO…
The recent eruption on La Palma, in the Canary Islands, has stimulated speculation that the volcano might collapse, creating a tsunami that would devastate the east coast of North and South America. But is such a scenario possible or likely?

Money is so short at the Goma Volcano Observatory (GVO) that staff members complained of sometimes lacking fuel for field trips, having computers that can’t process hefty data sets, and wearing faulty masks that don’t protect them from gases spewed out by Mount Nyiragongo.

The volcanologists have also faced health risks as a consequence o…
The morning after La Soufriere volcano carpeted St Vincent and the Grenadines with millions of tons of ash, disaster management expert La Fleur Quammie put on goggles and a mask to head through an eerie landscape to coordinate her team helping people in emergency shelters.
Months of awareness-raising and extensive TV, radio and social media messa…
Researchers have shown that human-caused climate change will have important consequences for how volcanic gases interact with the atmosphere.
The researchers, from the University of Cambridge and the UK Met Office, say that large-magnitude eruptions will have greater effects as the climate continues to warm. However, the cooling effects of small- and m…

But the long-running problem of poor policy coordination among government organizations charged with preparing for the n…
The use of multi-risk information systems is crucial in confronting the increasing risks posed by natural hazards. In some cases, risk is increasing due to inadequate land-use norms or regulations that allow for the construction of infrastructure in areas exposed to such natural hazards. In other cases, vulnerability increases due to lack of awareness o…

The eruption of Mount Nyiragongo, an active volcano in the Democratic Republic of the Congo (DRC), led to the deaths of at least 30 people. There could however be longer term health implications for residents of the area. Patrick DMC Katoto, who has studied the health effects of volcanoes in the DRC, provides insights into…
Scientists are working to understand how long it might take for people to move out of harm's way ahead of a future eruption of the Auckland Volcanic Field.
"The next eruption in the Auckland Volcanic Field could happen anywhere in the existing field, either on the land, or in the sea, so estimating how many people might be impacted carries a lot of unc…

The Covid-19 crisis has exposed the vulnerabilities of the economies of St. Vincent and the Grenadines, Barbados, Saint Lucia and other small, tourism-dependent Caribbean countries. These economies typically must contend with a limited availability of arable land, small and often scattered populations, fragile nat…

The readings, along with earthquake, temperature and gas data, are crucial to the region’s early warning system for the nearby city of Goma, to avoid a repeat of the 2002 eruption when 250 people died and 120,000 were made homeless.
Increased volcanic activity and other indicators have experts fretting…
The deadly eruption of Nevado del Ruiz in 1985 made Colombian volcanologists realize that studying natural phenomena was irrelevant if they could not share their knowledge to avoid predictable tragedies.
On 13 November 1985, the Nevado del Ruiz volcano erupted, killing more than 25,000 people in Armero—a town of 30,000 inhabitants—making it t…
The Mount Semeru crisis in Indonesia on Dec. 4 and 5 killed at least 43 people, with some 13 people are missing and at least 3,000 housing units damaged as of Dec. 9. Thousands of residents, especially the Lumajang Regency, East Jawa were displaced to the nearby villages.
The Governor of East Java, where the volcano is located, claimed the volcano earl…
The eruption of Mount Semeru in Indonesia on Saturday tragically claimed the lives of 22 people, with another 22 still missing and 56 injured. More than 5,000 people have been affected by the eruption, and more than 2,000 people have taken refuge at 19 evacuation points.
Saturday’s eruption produced an ash plume that reached 15km into the atmosphere, a…
Lara Mani was tired of hearing about the Yellowstone supervolcano. Every so often, another news story would appear, proclaiming that the Yellowstone caldera system could erupt with such ferocity that the impacts could cascade into a global catastrophe. “Yes, there’s plausibility in that,” said Mani, a research associate at the University of Cambridge’s…
