In 2017, Mount Agung in the Democratic Republic of Congo erupted.
It had been dormant since the 1950s, when a small group of settlers discovered the nearby Agung volcano.
They called it “The Big One.”
The eruption left a crater of more than 30,000 cubic metres, covering an area of about 300 square kilometres.
The eruption killed at least 7,000 people and left hundreds of thousands homeless.
Scientists say the eruption is responsible for the current mass mortality epidemic.
The scientists say the volcano was active when it erupted, and has since been dormant.
The world’s second-largest volcano, Mount Polungla in Nepal, erupted in 2014 and left more than 200,000 dead.
The death toll from the eruption has not been reported, but the scientists who conducted the first large-scale analysis of Polunglas activity say it is “likely” that it is responsible.
“Polungla has been active for more than half a century, and probably for decades,” says co-author Andrew Hodge of the University of Tasmania in Tasmania, Australia.
Polunglas is about 60 kilometres west of Kathmandu, and its eruption is believed to have triggered the current outbreak of pandemic-related deaths.
The scientists believe the volcano is dormant now, and that the recent increase in death tolls might have been caused by people trying to escape the pandemic.
