Hi all.

Just thought I'd drop in here to add a couple of links to interesting articles regarding volcanoes in NZ and off the coast of Oregon/Washington in the U.S..

Rotorua Geyser erupts after 35 years of inactivity By Moana Tapaleao 2:59 PM Wednesday Sep 9, 2015

I remember filming the geyser just before it stopped being active...did I jinx it smile It is an interesting one to see and the bubbling mud pools are fascinating too.

You may remember I pointed out some of the under-sea volcanic mounds (I was drawn to) in this general location (U.S. and Canada) quite a while ago. See the following report about an eruption west off the coast of Washington/Oregon recently (April 2015)...

Axial Seamount eruption of April 2015 confirmed, US Posted by Elena Ugrin on September 11, 2015

To catch up with other current volcanic activity, have a look at the Volcano Discovery website

Cheers for now, Duck.

Hi logansi and all.

Here are some interesting articles;

World's longest continental volcano chai...tember 15, 2015

Mexico’s Colima and Popocatepetl volcano...tember 12, 2015

Notice how many volcanoes have been going off in recent times, and near some of the locations where there is quite concerted EQ activity (generally near plate edges)? Interesting to say the least.

Japan's volcano activity is not surprising. This is one of the regions with some solid plate activity. Watch the U.S. for sneaky volcanic behaviours (even if minor). Not only will known volcanoes (some of them in various spots around the planet) will show and are showing activity, some more volcanic behaviours may crop up in locations considered 'dormant' or 'extinct' in the future (globally).

Cheers, Duck.

Was watching a documentary on ABC some time ago (this year), about the mechanisms governing one of Africa’s Savanna Volcanoes. Apparently there is a huge plume of upwelling magma, on the continental scale, creating changes in the surface landscape of Africa. In due course (on the geological time scale) this plume is said to “sink” Africa, forming inland lakes and eventually seas in the far future.

I can’t find any specific references to this information, but there probably are some if one knew where to look [I’m not an expert in this field].

I think, judging by the documentary evidence, it's having an impact now -- some of the wilder beast herds are on a massive scale at a very specific area downwind of the Volcano in question, because whatever the volcano is emitting (however regular/irregular that may be) it's impacting the chemical composition of grasslands (and presumably soils) in that location making them very fertile and suitable for grazing.

Evacuations occurring for people in Indonesia as fears Mount Agung will erupt (tremors becoming bigger and more frequent - ABC News). Last eruption 1963.

Looks like it could be on ,Bali's Mount Agung. Still giving off lots of tremors and increasing activity.

Would love to be able to check out a live seismic graph for this volcano. Anyone know where to watch one?

Watched a documentary on Krakatoa last night. That was one hell of an eruption. Seems some volcanoes in Indonesia have a habit of extremely violent eruptions.

The last eruption at Agung in the 1960's was a VEI5. Whilst nowhere near as big as Pinatubo (a VEI6) was in 1991 it does show Agung can have massive eruptions.

I wonder if it'll actually blow or just be annoying. The art of vulcanology seems to still be akin to reading tea leaves.

Where are you getting the information from -- I got it off the ABC news last night.

Considering lives could be at risk if Agung really does erupt significantly...I'd like to know the information I come across is equally reasonable.

...it is on our news bulletins, and has been consistently for many days?

Ok smile , as I said I got it from the TV News for SA....Wasn't aware of other sources (for this particular topic). They reported it again tonight as a headline.

Apparently the volcanologist said an eruption was expected within hours to days, based on the pattern of tremors (1000s each day).

Still no real news about Mt Agung other than reports "animals had fled the mountain and national emergency declared".

I think the way they report stuff like on the ABC on line. Will say updated 1 hour ago .But will be the same information as 18 hrs ago . Yes Kino not a lot of info coming out .Searched for seismograph links without luck.
