Not the most powerful volcanoes in the world, I'm afraid. Krakatoa (the first) was certainly powerful, but by no means the most powerful in the 19th
Century, which would be Mount Tambora's 1815 eruption, which caused the so called "Year Without a Summer". The most powerful volcanoes are of
course those capable of a Super Eruption. As far as anyone knows, these ones can't do that.
Tuesday 11th January 2011 Krakatau Volcano, Indonesia
...Visual observations showed ash emissions reaching a height of 600 m and drifting east. Ashfall has affected the operation of seismometers on the
volcano. Fisherman and tourists are advised to stay at least 2 km from the volcano.
A rather small eruption, to have an exclusion zone of only 2km and ash plume to 600m. Probably just Strombolian activity, given these details.
Wednesday 5th January 2011 Merapi Volcano, Indonesia
Lahars from Merapi volcano have destroyed several bridges including Gempol bridge on the Putih River. A lahar overflowed from the Putih River in
Jumaya village, Salam subdistrict, on Monday night, cutting off the Magelang-Yogyakarta highway at Kilometer 23 for almost 18 hours until about 1 p.m.
on Tuesday. More than 500 meters of the highway were submerged under meter-deep lahar. This was the most damage cause by merapi volcano since the
alert level was downgraded at end of December 2010.
This does not indicate any current volcanic activity, as far as this description is concerned. A lahar is just ash washed down by rainfall at it's
simplest, and one occuring is not without precedent for that area. Unless the alert level is upgraded, not much is happening there.
Wednesday 5th January 2011 Volcanoes of Colombia
Some activity to have concern over, perhaps, but impossible to say for sure. To compare, St Helens had a lot of quakes for a while a few years back,
and very little actually happened.
Saturday 8th January 2011 Kizimen Volcano, Kamchatka
On 1st January an ash plume extended 500 km SSW of the volcano and ashfall was recorded at Petropavlovsk-Kamchatsky, Yelizovo, Paratunka, Nalychevo
and all Southern Kamchatka. On 5th January ash emissions extended over 500 km ENE of the volcano and ashfall was recorded in the Komandorsky Islands.
On 5th December 2010 ash emissions reached a distance of 838 km NE of the volcano.
This one is a reasonable eruption, but really not much of a big problem, and unless activity intensifies not too worrying. It's about equal to the
Icelandic Eruption last April, from this description.
All in all, nothing too worrying here really. All of these are in the Pacific Ring of Fire, where such activity is expected and monitored all the
time, which is why we know about it. To suggest it is a sign of impending disaster is quite erroneous, really. Two of them are Decade Volcanoes,
Merapi and Galeras, but other than that these aren't that powerful.
