Recommended Posts

Since the Volcanic thread is locked for some unknown reason I'll post it here.

A repeat has come out about the last eurption at St Helens.

I don't read the blogs on here very often, but the one I did (maybe last month) was posted by Shetland Coastie. He was originator of the volcano thread, and I think, laterly, some people were abusing the topic, so he asked the mods to either delete it or close it? cc_confused.gif

Coastie?

that's a shame if that's true, cause coastie put huge amounts of efforts into the those threads. I will hold my hand up and admit that yes I haven't read those threads as much lately. but when I did I really enjoyed reading them.

Due to some stupid idiots the threads have been closed I think its a disgrace. the forum will suffer in the long run with out the quality of posts that will no longer be posted.

I agree with you 100% Cookie. A huge loss to the forum, and its a shame that the minority ruined it for the majority. I don't blame Coastie one bit though for packing it in.

Back on topic, a good read, thanks Pit for the link.

personally i enjoyed learning from the thread, and to be honest, i think SC should resurrect the thread and not let the minority spoil it for the majority (but thats just my opinion)

Just as a point of interest - the team didn't receive a single report about posts within that thread in recent times, it's a community folks and we all need to take a little bit of responsibility for its smooth running.

It's been a bit of a dull Summer with regards to volcanic activity, a few huffs and puffs here and there but nothing really of note except that Chaiten continues to erupt at a phenomenal rate. Hopefully we'll see some more activity soon.

Well if I get the time I may post the odd snippet of information that may interest people and if I get information wrong feel free to tell me I won't get upset.

Now Chiaten. If the people monitoring that posted decent information that would be useful.

I enjoyed reading the posts Shetland Coastie put together in the Volcano thread.

It would be nice if you could start it up again.

The silent majority I bet would also agree.

Elsewhere it's looking that the Montserratt Eurption is dying down http://www.gov.ms/?p=994

Chaiten continues to chug away http://volcanism.wordpress.com/2009/09/06/chaiten-bulletin-no-104-21-august-2009/

The size of the dome previously impressive must be eye boggling by now and still no major collapse. If it does it make one hell of a bang.

Activity at Redoubt remains low although the Dome is unstable and could collapse producing pryoclastic flows, Mud flows and ash clouds that could cause a hazard to airlines.

Large eruption at Russian volcano Shiveluch

heres the link:

http://wattsupwiththat.com/2009/09/12/large-eruption-at-rusian-volcano-shiveluch/

It seems as though Shiveluch in Kamchatka erupted yesterday with a decent sized eruption. Ash plume up to 7km.

Some good information over at The Volcanism Blog.

sorry fozi i should of read through the thread mods you can remove my post.:rolleyes:

Some nice pics of Shiveluch showing earlier eruptions. http://www.kscnet.ru/ivs/kvert/current/shv/index.html

Heres the update from KVERT

Activity of the volcano continues: a new viscous lava flow effuses at the lava dome. Ash explosions > 10 km (> 32,800 ft) ASL could occur at any time. The activity of the volcano could affect international and low-flying aircraft.

Seismic activity of the volcano decreased: only three explosive events occurred from 02:15 till 15:46 UTC on September 11. According to an interpretation of seismic signals, ash plumes rose up to 4.5-6.5 km (14,800-21,300 ft) ASL. No visual data about this events - the volcano obscures by clouds. According to satellite data, a thermal anomaly over the lava dome was registering on September 10-11

Interesting news from yellowstone. The uplift may have stopped.

http://volcanoes.usgs.gov/yvo/activity/

If the uplift continued it could well be a question of when an eruption occurs. This could well be a pause or it could be sign that the caldera is going to subside in the coming years instead of rising.

Does anyone who looks at this, or other threads in the forum have any idea what effect the plume set off by Shiveluch have on the northern hemisphere weather?

I only asked because I saw this photo on Spaceweather.com. It's a sunrise, not a sunset and it looks mighty red to me. Suggests lots of aerosols have already spread to Nebraska, but the date of the photo suggests they are not Shiveluch's aerosols. I know there were other eruptions during the summer, I assume the aerosols are from those

Hi TP, Seems the best place to get info on Chaitan is the blog here, interesting that within the piece it shows that it's still Red Alert down there, with that fact that it's come active after 9,000 years tends to suggest that it could be quite a large eruption, mainly due to the speed of growth of the dome.
