Vikings Volcanic Activity Thread

[Guest Viking141]

Flegrei and Ischia seem to be recording the most activity at the moment.

Did you get an answer back form the email you sent???????

Not yet but I would imagine they have been rather busy lately!

[Guest Viking141]

Hi all.

Still quite a lot of seismic activitiy in the Stromboli/Vesuvius/Bay of Naples area. Quite a lot showing up on the Baia station on the Campi Flegrei at the moment and a couple of recent big jolts at the Matese station. Still worth keeping an eye on this area.

The Italian volcanoes are indeed still rumbling away, Vesuvius recorded a large seismic tremmor between 4 and 8 this morning, and all the volcanoes seem to be recording constant activity at the moment.

Vulcano is still letting off gas by the way.

[summer blizzard]

Some activity occuring, but nothing major.

[Guest Viking141]

Still a fair bit of seismic activity in the Bay of Naples area this morning, the Puzzuoli station in particular showing a lot of tremors this morning. Stromboli itself, however, seems to have quietened down a lot.

Kliuchevskoy

Our old friend Kliuchevksoy in the Russian Far East (Kamchatka) continues to grumble away. According to latest reports activity has continued at above background levels over the past couple of weeks. Tokyo VAAC reports an eruption plume rising to an altitude of 20,000ft on 22/23 Feb and a local news report says there was ash fall in the village of Klyuchi, some 40km N of the volcano on 26 Feb.

Wow! Major tremor on the Matese seismograph!! Also ongoing activity at Stromboli, Ischia and Puzzuoli. This area is still highly active.

[Guest Viking141]

Some pictures of the recent Stromboli eruption on the Beeb website:

Still major seismic activity being picked up by the Matese seismograph, also some louder grumblings on the Ischia seismograph as well.

Good grief. Is there any way of telling the magnitude of the tremors from those seismographs?

Tunguruhua

Latest news from IG-EPN states that Tungurahua is again showing heightened levels of activity. The volcano continues to emit large amounts of gas and steam,accompanied by loud roaring noises and an incandescant glow from the main crater. During the night of 1/2 March, an explosive event, which was heard in the nearby area of Guadeloupe and described by locals as like a loud cannon shot, was accompanied by a steam, ash and gas column which reached a height of some 5kms. Slight ash-fall was reported to the SW of the Volcano in the villages of Manzano and Chogluntas. This explosive event was considered to be of moderate intensity.

Nevado Del Huila

INGEOMNIAS reports that activity at this volcano,which last erupted some 400 years ago,remains at an elevated level with plumes of steam and gas rising to altitudes of 18,700ft and continued fumarolic activity. Seismic events continue to be registered including one of Mag 2.7 on 27 Feb, which indicates the fracturing of rock within the volcano caused by magma rising towards the surface. The Colombian army base in the nearby town of Toribio reported some ash-fall on the town. This volcano is definitely one worth watching over the coming days and weeks.

Galeras

INGEOMINAS also reports a major seismic event connected with Volcan Galeras. This occurred at 0218 local time yesterday morning andwas located 2km NNE of the main crater of the volcano. It measured Mag 3.5 on the Richter scale and is again indicative of the likelihood of an eruption "within days to weeks."

hi viking, seems to be a lot of volcanic activity around the world at this moment in time, is this about normal or is it above average

cheers

[Guest Viking141]

The USGS insist it is quite normal and they have produced some graphs and charts to show that is the case, however that assessment was done several years ago. Since you are not the first person to have asked this question Im going to get in touch with one or two people in the know and see what they reckon, hopefully I can get back in a few days with more information.

could be quite interesting, keep up the good work on this fascinating subject

I have just had a look at the data for today, and while the Maltese activity was not on the same scale as that of Vesuvius on tuesday, it did last much longer.

What is the history of Maltese?????

Matese mountains are an offshoot of the Appenines which basically form the spine of Italy. If I remember correctly they form the western edge of the Campi Flegrei (Phlegrean Fields). The Campi Flegrei itself is a huge volcanic caldera, most of which lies underwater in the Bay of Naples. It is believed that this area was formed by two major volcanic events.The first, approx 40,000 years ago and then about 12,000 years ago a second major event (called the Neopolitan Yellow Tuff by vulcanoligists) formed a smaller caldera inside the first one, which is centred on the modern town of Pozzuoli (where one of the seismographs is located). In 1538, an 8 day eruption deposited so much material that it created a new new hill, appropriately called Monte Nuovo. Matese is also a National Park and a major tourist attraction.

Im rather staggered to realise that this thread,which I started just a little way back in late October last year, has been viewed over 5,000 times! Wow! I hope everyone has enjoyed reading it as much as I have writing it.

[Guest Viking141]

Holy c**p!! Check out this activity from the Matese seismograph.

[Red Raven]

Matese seems to have calmed down a little but it did show very rapid and abrupt seismic movement a little while ago. Seems the region is still on the move.

Are the cameras in the area showing activity.

Intense, but it had nothing on Vesuvius or Stromboli.

Have you recieved an email back to your questions?????

That should of course read "eastern" edge LOL! Well I was tired!

No not yet. I'll chase them up later today.

Incidentally the seismograph at Matese is still going wild!!

I wonder if last nights lunar eclipse highlights that the sun and moon's gravitational influence are quite opposed at the moment (pulling from opposite sides of the globe) leading to 're-adjustments' of any small amounts of tied up movement along global fault planes (and pulling apart spreading centres)?

Maltese is still recording strong seismic tremors and in my opinion, they are becoming more severe.

This map shows the location of all the volcanoes in Itlay..

[Guest Viking141]

They certainly are! Seems to be pretty intense at the moment. Seems to be a lot of pressure building up.

[robl1200]

A big shake at 21.53 on the Matese graph, intresting to note about the believed to be extinct Roccamonfina volcano, although according to the link it has a history of mostly seismic activity rather than volcanic.

How is there not an eruption at the moment..

[Guest Viking141]

Hi all. Not heard anything back from our Italian friends yet about the ongoing seismic action. I have, however, got an answer to the question about whether volcanic activity has been increasing. According to vulcanologists at the Smithsonian Institute and the USGS the answer is a definitive no. They will shortly be making available data which includes all volcanic activity up to 2006 to back up this assertion and I will post a link to it when they do.
