Manam Volcano just Exploded to 50,000 feet (15.2 km)

Yet another high-impact eruption took place at Manam volcano, Papua New Guinea on Friday June 28 — following on from the previous day’s explosion to 12.2 km, and the general uptick which began last year.

A thick volcanic ash plume, rising to at least 50,000 feet (15.2 km) above sea level, was spotted by the Volcanic Ash Advisory Center (VAAC) Darwin at 06:59 UTC on June 28 using HIMAWARI-8 satellite imagery.

The eruption comes hot on the heels of yesterday’s ejection to 40,000 feet (12.2 km).

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


“The situation is still continuing … the ash is still falling,” local islander Bill Sauba told ABC.

“There is ashfall covering about 6 villages because of the wind direction,” Sauba continued.


Things have been rocking in Papa New Guinea of late.

This latest explosion at Manan comes just two days after the full-scale subplinian eruption at nearby Ulawun — the world’s first subplinian eruption since Calbuco, Chile in 2015.

Humanitarian resources are reportedly already strained following that Ulawun eruption, which wound-up displacing some 15,000 people.


BACKGROUND

Manam volcano, located 13 km off the northern coast of New Guinea near Bogia town, is one of Papua New Guinea’s most active volcanoes.

It has one of the longest records of historic eruptions in the SE Pacific region. The larger eruptions of Manam produce pyroclastic flows and sometimes lava flows. Both have repeatedly reached the coast and affected populated areas. 

The volcano’s current ongoing eruptive phase technically began back on June 29, 2014 and it has already registered as a 4 on the Volcanic Explosivity Index (VEI).

Manam’s eruptive history is peppered with VEI 2s and 3s, but it also has two previous confirmed VEI 4s, from 2004 and 1919 — see volcano.si.edu for more.

UPTICK

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.
