On 22 December 2018, a tsunami that followed an eruption and partial collapse of the Anak Krakatau volcano in the Sunda Strait struck several coastal regions of Banten in Java and Lampung in Sumatra, Indonesia. The tsunami was caused by an undersea landslide that followed an eruption of Anak Krakatau, the “Child of Krakatoa”. On 23 December, it was found that much of the island of Anak Krakatau had collapsed into the sea.
The first tweet shows the changes in the volcano just over one one month.
The second shows the neighboring islands some of which have had the coastline scoured by the tidal wave.

Anak Krakatau now has a volume of 40 to 70 million cubic metres and lost 150 to 180 million cubic metres of volume since the Dec. 22 eruption and tsunami, according to Indonesia’s Centre for Volcanology and Geological Disaster Mitigation.
The analysis shows the scale of the island’s collapse, shedding light on the power of the tsunami that crashed into more than 300 kilometres of coastline in Sumatra and Java. More than 420 people died in the waves that were two metres or higher and 40,000 were displaced.
The centre said that the crater peak was 110 metres high as of Friday, compared with 338 metres in September
Anak Krakatau volcanic activity between 24.-26.Oct.2018. All explosions filmed in real time, even at night ! Note abundant volcanic lightning visible at night. Also lavabombs hitting into the sea and causing fires inside the forest. Daylight explosions with view into the crater from drone.
Interesting video about volcanoes and glaciers “starring” scientists from my alma mater.
I know the video is from the left-wing climate doom peddling CBC and it is quite shameful they use headlines implying climate change could “wake up” volcanoes.
I’ll concede that volcanoes can effect glaciers. But everything else is doom mongering.
A much better version of the story (from 3 months ago) is here.
“Researchers knew that fumaroles likely existed on the mountain — there had been reports of a sulphur-like smell near the mountain for years, not to mention hot springs in the area—but now, with the glaciers retreating, it seems they had emerged from beneath the snow and ice.”
