Now That IS interesting and new iformation! That even back then Munch sensed an ".. infinite scream passing through nature"...Wow. Sums up a lot of what seems to be happening with the earth these days. I've wondered about how the globe must be feeling but could never be as eloquent as Munch in either words or paint! Nature kicking off reminds us that we have never been in control. Makes you feel pretty humble, eh?
Not to go too off topic, but with the severing of one of earths major arteries in the gulf ,spewing her life blood for months on end, playing with the weather and dark matter, genetically modifying crops, (the list, of course goes on and on... ) it would be no wonder if there folllowed what we mere mortals consider unprecedented natural 'disasters'. If I was being abused the way we abuse earth I would quake, bleed and explode too!

Just to confirm: Anak Krakatau has not "just erupted". It's been having eruptions for years and the only matter of note is that its latest series of eruptions are more frequent than in some previous years.

A couple of details from John Seach, a volcanologist (Note: "Seach", not "Search" as it's frequently but wrongly spelled.):

Here is some data from Mr Seach on eruptions of Krakatau/Anak Krakatau since the "big one" in 1883:

Krakatau Volcano Eruptions

2007-10, 2001, 2000, 1999, 1997, 1996, 1994-95, 1992-93, 1988, 1981, 1980, 1979, 1978, 1975, 1972-73, 1969?, 1965?, 1959-63, 1958-59, 1955, 1953, 1952, 1950, 1949, 1946-47, 1946, 1945, 1944, 1943, 1942, 1941, 1938-40, 1937, 1936, 1935, 1932-34, 1931-32, 1927-30, 1883

Here's a short statement from Mr Seach about this volcano:

Krakatau (Krakatoa) Volcano lies in Sunda Strait between Sumatra and Java Islands. It belongs to Lampung Province. Krakatau Volcanic Complex consists of Rakata, Sertung, Panjang and Anak Krakatau Islands. Anak Krakatau is the currently active centre at the volcano and emerged from the sea in 1930.

and

2010 Eruptions
On 29th October 2010 there were 136 eruptions at the volcano, compared to a recent average of 10 per day. Krakatau volcano was raised to level 2 alert.

The source page for this information is here.

According to this highly respected scientist, there's no problem with using either Krakatau or Anak Krakatau. As he says, the volcano is Krakatau, and Anak Krakatau is the active part within its center. So, take your pick -- but don't be too picky over the name. We all know which volcano we're talking about.

Also, if you check the Smithsonian/USGS weekly volcanic activity report for last week, Krakatau doesn't even rate a mention. Yes, it was active and erupting last week, but not at a rate that concerned officials enough to advise USGS.

Obviously -- as Krakatau wasn't listed -- not all active volcanoes make that list. Just the ones that are of significant interest and/or concern to scientists. We can expect that Krakatau will make the list this week.

So, while it's true that Indonesian authorities are keeping a watch on (Anak) Krakatau, they've been doing so for years. It's not true that this volcano just started erupting; their concern and raised alert level is based on the fact that its number of eruptions has increased well beyond the average, and so it could be a problem if things continue to worsen there. It has had significant increases in activity before, several times, without any catastrophic eruption resulting from it (since 1883, I mean).

But right now, the authorities are probably more concerned about Merapi, because its current eruptions are different in character from most of those in the past century or so (which were "quieter") and more like those in centuries prior, so they fear it might have a major, "explosive" eruption with significant ejecta.

The mass media are often poor sources for good information about volcanic activity and seismic events. (Yeah, okay, and about a lot of other stuff, too. ) In cases like this, they rarely give much historical detail beyond the spectacular or most disastrous, and this can lead people to assume that every time a volcano like Krakatau erupts, it's going to be a major catastrophe. Sure, it sells newspapers and advertising space, but does little to inform the public of the real situation.

I'm not saying that things are not serious in Indonesia. Far from it: right now, the situation is pretty worrying, with eight volcanoes being raised to alert level II status in recent days. But Krakatau is nowhere near as big a concern as Merapi. For now, anyway.

Best regards,

Mike

Karkatau hasn't erupted. The RSOE EDIS website has updated it as such. All it says is:

The Anak Krakatau volcano located along the Sunda Strait produced 117 small eruptions on Thursday. The sound of the eruptions was audible to the Serang district in Banten, which is 40 kilometers away. “Anak Krakatau's activities has been escalating since Oct. 27,” said Sikin, a staff member at the Anak Krakatau monitoring post in Cinangka, Serang, as quoted by SCTV on Friday. According to Sikin, the volcano's status was increased to “be alert,” or two levels before a big eruption, since September. However, the situation is still considered safe for fishermen. “Fishermen must be cautious and try not to get too close to the mountain and maintain a minimum 4-kilometer distance,” Sikin said. Increased activity is also building up at the Galunggung volcano in Tasikmalaya, West Java. Heri Supartono, head of the Galunggung monitoring post, said that the volcano had triggered 34 earthquakes this month. “In September, there were only four volcanic earthquakes, but Galunggung's status is still normal because the water temperature around is still normal,” Heri said. “We monitor it every day and report the result to the Tasikmalaya municipal government,” he added. The 2,167-meter high volcano has erupted three times between 1822 and 1983. Another volcano, Dempo, at Pagaralam, South Sumatra, also showed signs of increased activity. “There have been tens of volcanic or tectonic earthquakes, but the magnitudes are relatively small so they don't affect the normal status of Demo volcano,” Slamet, the head of Dempo monitoring post, told state news agency Antara on Friday.

Shes stirring but she ain't gone boom..............yet!

Peace.
ALS

just found this one




what are the main signs of imminent explosion?

how much time in advance would scientists be warned?

just to start learning, if someone could help out i will appreciate
