Spectacular stratospheric eruption, volcanic ash to 19.2 km (63 000 feet) a.s.l. - Ulawun, P.N.G.

Satellite imagery obtained 08:30 UTC, June 26, 2019 indicate an ongoing volcanic ash eruption to approximately 19.2 km (63 000 feet) above sea level extending in all directions, the Darwin VAAC reported 08:34 UTC.

Volcanic ash to 13.4 km (44 000 feet) a.s.l. continues to drift S and is expected to dissipate within 6 hours.

"VA to 19.2 km (63 000 feet) a.s.l. which is stratospheric has become detached from the volcano and is moving eastwards," the center reported 11:30 UTC. "Volcanic ash to 16.7 km (55 000 feet) a.s.l. is extending rapidly outwards and bulging more in a southerly direction. The eruption appears to have ceased, with strong hotspot remaining."

Satellite imagery shows a large circular cloud over the volcano, indicating that this is most likely a full-scale subplinian eruption, the world's first since Calbuco, Chile in 2015, VolcanoDiscovery noted.
