Ulawun volcano, one of the most dangerous in the world, erupted Thursday morning in northeastern Papua New Guinea. Ash was spewed into the air for about 15 minutes, but the volcano then calmed down with no injuries.

The eruption produced plumes of smoke reaching up to 3,000 meters above sea level, sending a warning to air traffic.

Ulawun is on the list of the 16 “Volcanoes of the Decade” selected by the International Society of Volcanology as relevant for further study due to their history of violent eruptions and location in populated areas.

At 2,334 meters, Ulawun is the highest mountain in the remote Bismarck Archipelago. Several thousand people live in the area around the volcano. They were forced to flee their homes in 2019 as a result of a series of eruptions.
