With so many active volcanoes on the planet, tourists are seeking out thrills on mountains from Japan to DR Congo.
Some of those have had eruptions in the recent past but still – or possibly because of that – are high up on the list of visitors.

“But with the reward comes a range of risks. They can include sulphur dioxide and other toxic volcanic gases, material from the volcano being thrown out, lava flows and possible resulting wildfires, landslides and, for coastal locations, tsunamis.”
So here’s an overview of several of the world’s most popular and recently active volcanoes.
