Researchers have examined satellite images of Anak Krakatau to calculate the amount of rock and ash that sheared off into the sea.
They say the volcano has lost more than two-thirds of its height and volume during the past week.
Much of this missing mass could have slid into the sea in one movement.
It would certainly explain the displacement of water and the generation of waves up to 5m high that then inundated the nearby coastlines of Java and Sumatra.

Did more than crack it’s toe.
And the remains of the Krakatoa island that are bracketing the new volcano channeled the wave?
Waves could have been higher. Something minimized them.
oops
Indonesian officials raised the danger level for the Anak Krakatau volcano on Thursday to the second-highest level, increasing the size of the no-go zone around the volcano from two to five kilometers.
Local citizens were also urged to back away from coastal regions as more tsunamis could occur.
Last weekend’s deadly tsunami was triggered by a landslide from the volcano that was not accompanied by major seismic tremors, baffling an Indonesian tsunami-warning system that relies on detecting earthquakes.
AFP reporters talked to Indonesians who needed little urging from the government to avoid beaches after the sudden horror of the last tsunami, which killed 426 people and injured over 7,000 at last count.
The Indonesian government has evacuated about half of the 3,000 people who live on the island closest to Anak Krakatau. Massive evacuations have been ordered along the coast of the Sunda Strait, raising the total number of evacuees to over 40,000.
An official at the Krakatoa observatory said the alert status of the volcano was raised on Thursday morning due to a “change in the eruption pattern,” which raised concerns of another landslide unleashing another tsunami.
Indonesian authorities issued a warning for “extreme weather and high waves” on Wednesday, warning the weather is another factor that could cause parts of the weakened volcanic crater to collapse in a landslide. Heavy rain and high seas are also hampering efforts to rescue victims of the tsunami.
Air traffic has been rerouted around the volcano due to volcanic ash filling the atmosphere, but no airports have been closed so far. The volcano is now said to be erupting nearly every minute, sending ash up to a mile in the sky with every pulse.
LOL! I know right. Then end of the year is rapidly approaching and we need to post as much stuff as we can right?
Watching ND v Clemson. Multi-tasking fail on my part.
Meanwhile Mt Agung on Bali had Live Feed of erupting lava overflowing the rim in the past couple days. 7.1 earthquake today in Philippines.
Interesting link....
Norte Dame. They were ranked #3? Didn’t play like it.
So, Global Warming?
Mama Nature adjusting her girdle. ;-)
Ended up switching over to Mythbusters until the Orange Bowl comes on.
Thanks!
You’re welcome! If my translator is working ok, looks like activity may have fallen off a bit. I’ll see if I can scare up an update....
It’s looks like that might be a live cam?
I think so. Meantime, two more links with some great pics, second link posted on line about 30 minutes ago...
From the photos (above) it does appear that the southwest quadrant of the volcano collapsed, yet the deadliest waves it Lampung to the north and Sumur to the southeast.
My grandchildren are on school holiday, and I had booked a bungalow at our usual beach digs in Anyer for Thursday 27/12. I thought we really dodged a bullet, but yesterday I rang them up and the lady at the resort told me they suffered minimal damage. The main problem is that the road to there is jammed up and damaged.
It may be assumed that Pulau Krakatau Kecil blocked the main wave from moving to the northeast with deadly force. Note further that Carita and Sumur were more badly damaged than was Tanjung Lesung, which had Pulau Krakatau between it and Anak Krakatau.
