Krakatau, a small island group in the Sunda Strait between the islands of Sumatra and Java is one of the world's most famous volcanoes. It is a mostly submerged caldera with 3 outer islands belonging to the rim and a new cone, Anak Krakatau, that has been forming a new island since 1927 and remains highly active.
Krakatau exploded spectacularly in a devastating Plinian eruption 1883 that killed more than 30,000 people (mostly by the huge tsunamis triggered by the eruption). The eruption was one of the first global news events after telegraph lines had connected the different continents.

Moment of the explosion at Anak Krakatau last night (image: VSI webcam) The volcano remains active. While it has been mostly comparably most of the time, it is emitting lots of gas and steam, probably small explosions, and at night shows near constant glow. ...plusIn addition, a powerful explosion occurred from its crater last night, at 20:54 local time. The eruption lasted only a few minutes and was probably a vulcanian-type event. Glowing lava bombs landed on the outer slope of Anak Krakatau. Here's the event captured by the webcam still operating on the island:

Lava fountain at Anak Krakatau last night Last night's violent paroxysm at Anak Krakatau ended abruptly around 08:00 morning local time. Fortunately, the webcam on the island survived the eruption although it seems it was hit by a projectile at 02:33 local time, when it suddenly tilted. ...plusThe following timelapse video shows the eruption from beginning to end, allowing the chronology and reconstruction of the various phases of the paroxysm: After dark, at around 20:00 local time, increasingly larger plumes can be seen rising from the new crater of Anak Krakatau, probably emissions of steam and ash generated by the first explosions, likely phreatomagmatic in nature when rising magma pushed its way up to the still partially lake filled crater and leading to explosive interaction between magma and water (phreatomagmatic activity).

Lava fountains from Anak Krakatau this evening (image: MAGMA Indonesia webcam)
A large magmatic eruption is taking place at the volcano right now. Based on satellite imagery, VAAC Darwin spotted a high-level ash and SO2 plume reaching 47,000 ft (15 km) altitude moving WNW. ...plusA strong thermal hot spot is detected as well. Both the webcam on Anak Krakatau Island and from the coast (in 40 km distance) show strong lava fountaining from the volcano. This seems to be the strongest eruptive phase since the violent phreatomagmatic activity following the partial collapse of the volcano on 22 Dec 2018, which had triggered a deadly tsunami that killed hundreds of people on Java's west coast.

 Books about Volcanoes: A selection of great books about volcanoes and volcanism, grouped into sections of different reading level interest.  Mayon volcano photos: Mayon on Luzon Island, towering above Legazpi city is famous for being one of the most perfectly symmetrical stratovolcanoes in the world. It is also one of the most active and most dangerous volcanoes (not only) in the Philippines.  Batu Tara photos: A remote island in the Flores Sea of Indonesia formed by a single volcano that has been in strong strombolian eruption for years. We regularly lead expeditions to there where we camp several days to observe it.  Depuis 1997, Tom Pfeiffer et notre équipe proposent des voyages en petits groupes, des randonnées et du trekking, ainsi que des expéditions pour voir des volcans actuellement en activité, des voyages photographiques dans de nombreuses régions d’activité volcanique à travers le monde.
