Another strong eruptive phase (paroxysm) is currently going on at the volcano.
Seismicity at Anak Krakatau has sharply increased during the past days and now shows continuous explosive/effusive activity. The observatory informed us that a lava flow is occurring from the summit vent, likely accompanied by lava fountaining, similar to what we observed in Sep and Nov during our latest expeditions to Krakatau.
This is what it probably looks like now:

Stop Russia's Agression - Support Ukraine
Significant parts of this website use brilliant open-source software developed by Ukrainians. Russia's unprovoked war has killed tens of thousands, displaced millions, and the beautiful country of Ukraine is being destroyed. We cannot be silent even if the topic of this website has nothing to do with politics.

Ukrainians recommend the Come Back Alive charity. For other options, see StandWithUkraine.
