The preliminary ash column height has been estimated to be upward of 9km by the Volcanic Ash Advisory Centre (FL320).

Strong sulphur smell has been reported - and the SO2 plume is now captured by OMI:

Here is the seismometer record... which broke at the time of the eruption (10.30 El Salvador 16.30 UTC)

in the eq thread, some time ago, i mentioned my feelings about more under-sea volcanic behaviours potentially occurring as a consequence of major plate activity.

see the link below for some articles regarding this happening. the latest to be reported on is one in/near the solomon islands.

volcanic eruptions - EP

volcano discovery is a great site.

volcano discovery - volcano webcams see drop down list top left of screen to choose a volcano location/country

for now, duck.

The Jakarta Globe is reporting an ash plume from the eruption of ~10 km with ash falling upwards of 50 km from the volcano. Apparently the sound of the explosion was heard 200km away...

SO2 emissions will be captured here on the next update

It's incredible isn't it Rorschach.

So many volcanoes going off, spectacular sights mixed with the problems some of them are causing for local communities.
For an explosion to be heard 200kms away, imagine the power behind that? wow
Mother Earth makes me feel like an ant sometimes.
All of the volcanic emissions must be having some sort of effect on the atmosphere.

Cheers, Duck.

This one is going to cause a few detours for flights to/from Singapore, Banglok etc. The ash plume is now apparently well over the top of usual flight levels at FL550 (55,000ft / 16.7km).

You can see how quickly the cloud is expanding... currently over the Indian ocean - so maybe the flights to SE Asia will not be troubled that much...

The ash and SO2 plume looks like it punched through into the stratosphere... This ones probably going to be eventually classified as a VEI4.
See below for lidar satellite data:

I know very little on the subject of volcano's, but some of you may find this link interesting.

http://home.iprimus.com.au/foo7/volcmap.html#6

Not sure if it is the real deal or scare mongering, but it is thought provoking.

It is real. Volcanos last erupted on the Australian mainland about 4-5,000 years ago. The local Aboriginal tribes in the areas around Mt Schank and Mt Eccles have stories of the eruption and how it changed the landscape.

I am aware of the Newer Volcanic Province and have climbed Mt Shank on a few occasions. What I am not sure about is the fact that hotspots stay in one place and the crust moves over the top of them creating a chain of volcano's such as the Hawaiian islands.
With the possible formation of a volcano in bass strait it seems impossible for the newer volcanic province hotspot to be creating this new vent. My reasons in saying this is the Eastern part of the field is the older part of the volcanic region and Mt Gambier and Mt Shank are the youngest formations and are located on the western side of the province. Either the tectonic plates have changed direction, the hotspot has moved or a new area is forming under the mantle. going from previous eruptions you would expect a new volcano to form somewhere west of Mt Gambier/Mt Shank, perhaps of the coast of the Coorong, Not in the middle of Bass strait.

Hi guys.

The following is my very, very generalized feeling regarding hotspots, plate movements and volcanoes.

I feel that hotspots have the potential to move and that some plate activity (causing EQ's and volcanic behaviour in some cases) is driven by the hotspots and upwellings.

There appears to be 'permanent' hotspots, like Hawaii, but there may be potential for others to develop if the energy conditions are right.

The volcanic activity, or general lack of at the moment, in Australia may be that there perhaps isn't enough of that driving energy affecting the Oz mainland, considering we are situated fairly central on the Australian Plate. But, this is not to say that some of the upwelling, plate and other activity causing some of the volcanic activity increase in other regions surrounding the Pacific Plate and Australian Plate may not 'splinter-off' in small ways into the edges of our plate - which may at some time cause some jitters in our volcanic plains here and there.
It could be a bit like the 'big-guy' stealthily poking at the arm (edge), sneaking a bit of that energy into our region, but not enough at the moment to cause concerns of a volcanic eruption on the Oz mainland.
I guess that if Mother Earth really got 'boiling' into overflow/overdrive with upwelling and plate movement, we may see some jitters in some volcanic regions in Oz. For this to happen, I am guessing that a larger event to the south or east of Oz may need to occur for there to be enough power to cause some of our volcanoes to react by degrees.

Just a thought,
Duck wink

Just as a matter of interest, I came across an old article, that I had forgotten about in my bookmarks, which discusses EQ's, volcanoes etc., in Australia.
I'll jot the link here, but it is also relevant to the earthquake thread;

"Land of earthquakes and volcanoes?" BY Kevin McCue | February 26, 2010
in the Australian Geographic.

Cheers, Duck.

Hi guys.

Here's a fascinating video of the African continent and how satellites are being used to determine volcanic locations' rises and falls, and gaging potential eruption.
Here's the article, in which the video below is from - A satellite view of volcanoes finds the link between ground deformation and eruption



For now, Duck.
