It looks like northern Japan coastal ports have seen tsunami waves arriving already, but so far just 30-70 cm high. Later-arriving peaks could be higher, but that is good news that the ultimate size will be moderate. I hope so! Damage reports sketchy so far, but also some reason for optimism.

Y'all the latest episode of the #Kilauea #eruption just went CRAZY. It looks like pressure built up enough to explode out the ground around the two existing vents (first few seconds), leading to a massive surge in lava fountaining.🌋🤯

Vulkanen maken bij het uitbarsten geluid, zelfs als wij het niet kunnen horen. Zo was de uitbarsting van de Nyiragongo-vulkaan in de Democratische Republiek Congo op 22 mei 2021 in detail te volgen door onhoorbare geluidsgolven te analyseren.

Pre- and post-eruption visible imagery of #HayliGubbi from #Sentinel-2, showing tephra deposits and 2 new craters. The latter could be eruption vents and/or formed by post-eruptive subsidence. Looks like the pre-existing crater was enlarged by the eruption. @esa.int

The weeks prior to the eruption, there is something filling the lake on and off... what the hell is that? liquid or gas?

An explosive #eruption of Hayli Gubbi #volcano, located SE of Erta'Ale in the Afar Rift (Ethiopia), began at ~08:30 UTC on Nov 23. Eruption onset was fortuitously captured by a @planet.com overpass at 08:31 UTC. Hayli Gubbi has no record of Holocene eruptions. Toulouse VAAC reporting ash to ~15 km.
