Chaiten’s volcano still erupting and provocated more destruction in Chaiten’s town. The flood of Blanco river has left only destruction on many houses olmost 40% of town is under flood. This is product of intensive rain over erosion slope provocated by forest loss take it bay “lahar” after the Chaiten’s eruption.

In personal way I’ve been there on january 2005 in a hostel called “la iquiqueña” . A very Quite Town without violence and corruption olmost a paradise in the middle of a beauty landscape.

I believe the eruption helps to create the conditions to a climate change in long terms like any eruption that remains for a long time.

Chaiten is ever so slowly ramping up:

Gary, not only the 6th Century. The end of the warm period in the 13th Century may also be attributed to Krakatau. There were some Vulconologists from the U.S. as well as some representatives form the Indonesian Volcanological Institute. (V.S.I.) who were poking around Tanjung karang and Lampung (at the bottom of Sumatera) looking for evidence of this many years ago. These guys had a film documentary team with them so I don’t know if there was a doco made. I haven’t been able to find any documents related to this search.
Apparently they found some sedimentary and tree ring evidence regarding the sixth and the 13th century eruptions and tree rings.

Terry, these plinian ash column eruptions (the ones that have the potential to affect the climate) occur about 8 times a century. Two at the same time would be a once in several thousand years event.

As Terry has asserted, It is way to early to make any long term judgements about the effects that Chaiten may have.
In 1883,Krakatau’s initial large eruptions took place in May. It was August when the great eruption and collapse occurred.

Sabreman. These electrical effects are normal. One of the hazards getting stuck in the wrong place during a volcanic eruption is being struck by lightning.

A very good source of info is on John Seach’s site. (As has been pointed out earlier.) – http://www.volcanolive.com/index.html

Phillip_B, at any given time there are 10 volcanoes or more in eruption. I follow them at this site: http://www.volcano.si.edu/reports/usgs/

You can also look at large historical eruptions at this link: http://www.volcano.si.edu/world/largeeruptions.cfm try to link them up with down spikes in the global temperature anomaly. There are quite a few that did not have any effects on the global temperature anomaly at all.

It is waaaaaaaaay too early to tell to make assumptions about Chaiten and any other volcano that might be in eruption right now.

Any comments on the intense electrical activity ??

A Kamchatka volcano has started to erupt after a moderate quake.

A Northern and Southern hemisphere double-whammy would not be good news for the Earth’s climate.

Saturday 10th May 2008
Chaitén Volcano, Chile
Eruptions continue at Chaitén volcano in Chile. Small pyroclastic flows have been observed at the volcano descending eastwards into Raya river. Yesterday, the eruption column reached an altitude of 14 km at 2pm, which drifted northeast. A new crater has opened up at the western base of the dome. Seismic monitoring equipment has been moved from the town of Chaitén to a safer location on Talcán island. The number of volcano-tectonic earthquakes remains constant at 35 events per day, concentrated on the outer regions of the volcano. Two large explosions occurred on 6th and 7th May (23:35 hr). A shallow reservoir of magma at 5 km depth has been ascending towards the surface. Breaking of rock in the conduit due to magma ascent has been responsible for the large explosions. An ongoing hazard at the volcano is the collapse of eruption columns, or dome collapse, creating pyroclastic flows which descend radially from the volcano into adjacent valleys. Helicopter overflights will continue to visually monitor the volcano as well as retrieve seismic data. The alert level remains at the highest rating, RED.

Info on Volcanic cooling effects here
http://volcano.und.edu/vwdocs/Gases/climate.html

According to NASA monitoring the SO2 content has so far not been large compared to the total of ejecta. However this could change as the eruption continues.
The ash fall surrounding the volcano will cause some problems particularly in the farming areas.
There has been a report that another crater has emerged on the western side of the dome.
