Ulawun’s Activity revised-up to a Full-Scale Subplinian Eruption — Ash Fired to 63,000 feet (19.2 km)

Ulawun’s earlier eruption to 50,000 feet (15.2km) today, June 26, has just been revised to that of a full-scale subplinian eruption, the world’s first since Calbuco, Chile in 2015, which ranked as a VEI 4.

The Volcanic Ash Advisory Center (VAAC) Darwin is warning of a colossal ash column rising to at least 63,000 feet (19.2 km) a.s.l., and comfortably into the stratosphere.

Particulates ejected to altitudes above 32,800 feet (10 km) have a direct cooling effect on the planet.

This latest eruptive activity looks set to be at least as big as 2000’s eruption, which ranked as a VEI 4.

Satellite imagery shows a large circular cloud over the volcano:

The volcano, located on the remote Bismarck Archipelago, is listed as one of 16 “Decade Volcanoes” targeted for research because they pose a significant risk of large, violent eruptions. 

Stay tuned for updates.


Ulawun, also known locally as the “Father” is a symmetrical large stratovolcano on New Britain Island.

It is one Papua New Guinea’s most active and most dangerous volcanoes. And rising to 2334 m, it’s also the highest of the 1000 km long chain of the Bismarck volcanic arc which stretches from Rabaul volcano in the East to Wewak in the west and contains no less than 21 active volcanoes. 

The “Father” has a busy eruptive history, peppered with VEI 2s and 3s — it’s largest confirmed explosion began on Sept 28, 2000 and last for around a month, eventually registering as a 4 on the Volcanic Explosivity Index, according to www.volcano.si.edu.

This latest eruptive activity looks set to be at least as big as that.

Seismic and Volcanic activity has been correlated to changes in our sun.

The recent global uptick in earthquakes and volcanic eruptions is likely attributed to the drop-off in solar activity, coronal holes, a waning magnetosphere, and the influx of Cosmic Rays penetrating silica-rich magma.
